    Patients' attitude and knowledge about oral anticoagulation therapy: results of a self-assessment survey in patients with atrial fibrillation conducted by the European Heart Rhythm Association.2016In: Europace, ISSN 1099-5129, E-ISSN 1532-2092, Vol. 18, no 1, p. 151-155Article in journal (Refereed)
    Abstract [en]

    The purpose of this European Heart Rhythm Association survey was to assess the attitude, level of education, and knowledge concerning oral anticoagulants (OACs) among patients with atrial fibrillation (AF) taking vitamin K antagonists (VKAs), non-VKA oral anticoagulants (NOACs) or antiplatelets. A total of 1147 patients with AF [mean age 66 ± 13 years, 529 (45%) women] from 8 selected European countries responded to this survey. The overall use of OACs and antiplatelets was 77 and 15.3%, respectively. Of the patients taking OACs, 67% were on VKAs, 33% on NOACs, and 17.9% on a combination of OACs and antiplatelets. Among patients on VKAs, 91% correctly stated the target international normalized ratio (INR) level. The proportion of patients on VKA medication who were aware that monthly INR monitoring was required for this treatment and the proportion of patients on NOAC who knew that renal function monitoring at least annually was mandatory for NOACs was 76 and 21%, respectively. An indirect estimation of compliance indicated that 14.5% of patients temporarily discontinued the treatment, and 26.5% of patients reported having missed at least one dose. The survey shows that there is room for improvement regarding education and adherence of patients taking OACs, particularly regarding monitoring requirements for NOACs.

    EHRA research network surveys: 6 years of EP wires activity2015In: Europace, ISSN 1099-5129, E-ISSN 1532-2092, Vol. 17, no 11Article in journal (Refereed)
    Abstract [en]

    Clinical practice should follow guidelines and recommendations mainly based on the results of controlled trials, which are often conducted in selected populations and special conditions, whereas clinical practice may be influenced by factors different from controlled scientific studies. Hence, the real-world setting is better assessed by the observational registries enrolling patients for longer periods of time. However, this may be difficult, expensive, and time-consuming. In 2009, the Scientific Initiatives Committee of the European Heart Rhythm Association (EHRA) has instigated a series of surveys covering the controversial issues in clinical electrophysiology (EP). With this in mind, an EHRA EP research network has been created, which included EP centres in Europe among which the surveys on 'hot topic' were circulated. This review summarizes the overall experience conducting EP wires over the past 6 years, categorizing and assessing the topics regarding clinical EP, and evaluating the acceptance and feedback from the responding centres, in order to improve participation in the surveys and better address the research needs and aspirations of the European EP community.

    Catheter ablation for atrial fibrillation: results from the first European Snapshot Survey on Procedural Routines for Atrial Fibrillation Ablation (ESS-PRAFA) Part II2015In: Europace, ISSN 1099-5129, E-ISSN 1532-2092, Vol. 17, no 11, p. 1727-1732Article in journal (Refereed)
    Abstract [en]

    The European Snapshot Survey on Procedural Routines in Atrial Fibrillation Ablation (ESS-PRAFA) is a prospective, multicentre snapshot survey collecting patient-based data on current clinical practices during atrial fibrillation (AF) ablation. The participating centres were asked to prospectively enrol consecutive patients during a 6-week period (from September to October 2014). A web-based case report form was employed to collect information of patients and data of procedures. A total of 455 eligible consecutive patients from 13 countries were enrolled (mean age 59 ± 10.8 years, 28.8% women). Distinct strategies and endpoints were collected for AF ablation procedures. Pulmonary vein isolation (PVI) was performed in 96.7% and served as the endpoint in 91.3% of procedures. A total of 52 (11.5%) patients underwent ablation as first-line therapy. The cryoballoon technique was employed in 31.4% of procedures. Procedure, ablation, and fluoroscopy times differed among various types of AF ablation. Divergences in patient selection and complications were observed among low-, medium-, and high-volume centres. Adverse events were observed in 4.6% of AF ablation procedures. In conclusion, PVI was still the main strategy for AF ablation. Procedure-related complications seemed not to have declined. The centre volume played an important role in patient selection, strategy choice, and had impact on the rate of periprocedural complication.

    Clinical management of arrhythmias in elderly patients: results of the European Heart Rhythm Association survey2015In: Europace, ISSN 1099-5129, E-ISSN 1532-2092, Vol. 17, no 2, p. 314-317Article in journal (Refereed)
    Abstract [en]

    The purpose of this survey was to assess clinical practice in management of cardiac arrhythmias in elderly patients (age ≥75 years) in the European countries. The data are based on an electronic questionnaire sent to the European Heart Rhythm Association Research Network members. Responses were received from 50 centres in 20 countries. The results of the survey have shown that management of cardiac arrhythmias is generally in accordance with the guidelines and consensus recommendations on management of cardiac arrhythmias, although there are some areas of variation, especially on age limit and exclusion of elderly patients for anticoagulation, ablation, and device therapy.

    Management of patients with ventricular tachycardia in Europe: results of the European Heart Rhythm Association survey2015In: Europace, ISSN 1099-5129, E-ISSN 1532-2092, Vol. 17, no 8, p. 1294-1299Article in journal (Refereed)
    Abstract [en]

    The purpose of this European Heart Rhythm Association (EHRA) survey was to assess clinical practice in the management of ventricular tachycardia (VT). The data are based on an electronic questionnaire sent to the members of the EHRA Research Network. Responses were received from 31 centres in 16 countries. The results of the survey show that the management of VT is in general in accordance with guidelines. Antiarrhythmic drugs are still frequently used for VT treatment. In patients at high risk of sudden cardiac death, an implantable cardioverter-defibrillator is routinely recommended, while the treatment options vary for patients with moderate or low risk. A discreet attitude is adopted for catheter ablation in high-risk patients as demonstrated by a relatively low rate of catheter ablation.

    Perioperative management of antithrombotic treatment during implantation or revision of cardiac implantable electronic devices: the European Snapshot Survey on Procedural Routines for Electronic Device Implantation (ESS-PREDI)2016In: Europace, ISSN 1099-5129, E-ISSN 1532-2092, Vol. 18, no 5, p. 778-784Article in journal (Refereed)
    Abstract [en]

    The European Snapshot Survey on Procedural Routines for Electronic Device Implantation (ESS-PREDI) was a prospective European survey of consecutive adults who had undergone implantation/surgical revision of a cardiac implantable electronic device (CIED) on chronic antithrombotic therapy (enrolment March-June 2015). The aim of the survey was to investigate perioperative treatment with oral anticoagulants and antiplatelets in CIED implantation or surgical revision and to determine the incidence of complications, including clinically significant pocket haematomas. Information on antithrombotic therapy before and after surgery and bleeding and thromboembolic complications occurring after the intervention was collected at first follow-up. The study population comprised 723 patients (66.7% men, 76.9% aged a parts per thousand yen66 years). Antithrombotic treatment was continued during surgery in 489 (67.6%) patients; 6 (0.8%) had their treatment definitively stopped; 46 (6.4%) were switched to another antithrombotic therapy. Heparin bridging was used in 55 out of 154 (35.8%) patients when interrupting vitamin K antagonist (VKA) treatment. Non-vitamin K oral anticoagulant (NOAC) treatment was interrupted in 88.7% of patients, with heparin bridging in 25.6%, but accounted for only 25.3% of the oral anticoagulants used. A total of 108 complications were observed in 98 patients. No intracranial haemorrhage or embolic events were observed. Chronic NOAC treatment before surgery was associated with lower rates of minor pocket haematoma (1.4%; P= 0.042) vs. dual antiplatelet therapy (13.0%), VKA (11.4%), VKA + antiplatelet (9.2%), or NOAC + antiplatelet (7.7%). Similar results were observed for bleeding complications (P= 0.028). Perioperative management of patients undergoing CIED implantation/surgical revision while on chronic antithrombotic therapy varies, with evidence of a disparity between guideline recommendations and practice patterns in Europe. Haemorrhagic complications were significantly less frequent in patients treated with NOACs. Despite this, the incidence of severe pocket haematomas was low.

    European Heart Rhythm Association (EHRA) position paper on arrhythmia management and device therapies in endocrine disorders, endorsed by Asia Pacific Heart Rhythm Society (APHRS) and Latin American Heart Rhythm Society (LAHRS)2018In: Europace, ISSN 1099-5129, E-ISSN 1532-2092, Vol. 20, no 6, p. 895-+Article in journal (Refereed)
    Abstract [en]

    Endocrine disorders are associated with various tachyarrhythmias, including atrial fibrillation (AF), ventricular tachycardia (VT), ventricular fibrillation (VF), and bradyarrhythmias. Along with underlying arrhythmia substrate, electrolyte disturbances, glucose, and hormone levels, accompanying endocrine disorders contribute to development of arrhythmia. Arrhythmias may be life-threatening, facilitate cardiogenic shock development and increase mortality. The knowledge on the incidence of tachy-and bradyarrhythmias, clinical and prognostic significance as well as their management is limited; it is represented in observational studies and mostly in case reports on management of challenging cases. It should be also emphasized, that the topic is not covered in detail in current guidelines. Therefore, cardiologists and multidisciplinary teams participating in care of such patients do need the evidence-based, or in case of limited evidence expert-opinion based recommendations, how to treat arrhythmias using contemporary approaches, prevent their complications and recurrence in patients with endocrine disorders. In recognizing this close relationship between endocrine disorders and arrhythmias, the European Heart Rhythm Association (EHRA) convened a Task Force, with representation from Asia-Pacific Heart Rhythm Society (APHRS) and Sociedad Latinoamericana de Estimulacion Cardiaca y Electrofisiologia (SOLAECE), with the remit of comprehensively reviewing the available evidence and publishing a joint consensus document on endocrine disorders and cardiac arrhythmias, and providing up-to-date consensus recommendations for use in clinical practice.

    Implantable cardioverter defibrillator use for primary prevention in ischaemic and non-ischaemic heart disease-indications in the post-DANISH trial era: results of the European Heart Rhythm Association survey2017In: Europace, ISSN 1099-5129, E-ISSN 1532-2092, Vol. 19, no 4, p. 660-664Article in journal (Refereed)
    Abstract [en]

    Implantable cardioverter-defibrillator (ICD) is the standard of care for prevention of sudden cardiac death (SCD) in high-risk patients. For primary prevention of SCD, in patients with ischaemic heart disease, there is more robust data on the effect of ICD therapy compared with patients with non-ischaemic heart disease, but current real-life practice may differ substantially. The aim of this European Heart Rhythm Association survey was to evaluate the clinical practice regarding implantation of ICD for primary prevention among European countries in patients with non-ischaemic and ischaemic heart disease. Furthermore, we wanted to investigate the impact of the results of the recently published DANISH trial on clinical practice among European countries. In total, 48 centres from 17 different countries responded to the questionnaire. The majority did not implant ICD for primary prevention on a regular basis in patients with non-ischaemic heart disease despite current guidelines. Also, centres have changed their indications after the recent report on the efficacy of ICD in these patients. In patients with ischaemic heart disease, the guidelines for primary prevention ICD were followed on a regular basis, and no relevant change in indications were reported.

    Patients' knowledge and attitudes regarding living with implantable electronic devices: results of a multicentre, multinational patient survey conducted by the European Heart Rhythm Association2018In: Europace, ISSN 1099-5129, E-ISSN 1532-2092, Vol. 20, no 2, p. 386-391Article in journal (Refereed)
    Abstract [en]

    The purpose of this patient survey was to analyse the knowledge, experiences, and attitudes regarding cardiac implantable electronic devices (CIED) in patients with pacemakers, implantable cardioverter-defibrillators (ICDs), or cardiac resynchronization devices. Of the 1644 patients with CIEDs from seven European countries, 88% were over 50 years of age. Most patients (90%) knew what device they were implanted with and felt sufficiently informed about the indications for therapy. As many as 42% of patients needed additional information on the battery replacement and limitations in physical activity. The self-reported incidence of complications was 9%, and among these, a quarter of the respondents felt insufficiently informed about the possibility of complications and their management. The majority of patients (83%) were followed by face-to-face visits, which was the most commonly preferred follow-up strategy by the patients. Nearly 75% of the patients reported improved quality of life after device implantation, but about 40% had worries about their device. Less than 20% had discussed with their physician or thought about device handling in the end-of-life circumstances or end-stage disease. Notably, almost 20% of the ICD patients did not wish to answer the question regarding what they wanted to be done with their ICD in case of end-stage disease, indicating the challenges in approaching these issues.

    Atrial fibrillation burden, episode duration and frequency in relation to quality of life in patients with implantable cardiac monitor2021In: IJC Heart & Vasculature, E-ISSN 2352-9067, Vol. 34, article id 100791Article in journal (Refereed)
    Abstract [en]

    Aims: To assess the relation between atrial fibrillation (AF) characteristics and health-related quality of life (QoL), and which AF characteristic had the greatest impact.

    Method: The AF characteristics burden (percentage of time in AF), duration and number of AF episodes/month were obtained from implantable cardiac monitors during the 2-month run-in period in 150 patients included in the randomized CAPTAF trial comparing early ablation and antiarrhythmic drug therapy. The QoL was measured by the General Health and Vitality dimensions of the 36-Item Short-Form Health Survey. AF characteristics were analysed continuously and in quartiles (Q1-Q4).

    Results: Greater AF burden (p = 0.003) and longer AF episodes (p = 0.013) were associated with impaired QoL (Vitality score only) in simple linear regression analyses. Greater AF burden was, however, the only AF characteristic associated with lower QoL, when adjusted for sex, type of AF, hypertension, heart rate above 110 beats per minute during AF, and beta-blocker use in multiple linear regression analyses. For every 10% increase in AF burden there was a 1.34-point decrease of Vitality score (95% confidence interval (CI) -2.67 to -0.02, p = 0.047). The Vitality score was 12 points lower (95% CI -22.73 to -1.27, p = 0.03) in patients with an AF burden > 33% (Q4) versus those with < 0.45% (Q1), but only in unadjusted analysis.

    Conclusion: AF burden had a greater impact on QoL (Vitality), than the duration and number of AF episodes, corroborating that AF burden may be the preferred outcome measure of rhythm control in trials including relatively healthy AF populations.

    The results of health-related quality of life assessment depend on the prevailing rhythm at the assessment: Experience from the CAPTAF trial (Catheter Ablation Compared with Pharmacological Therapy for Atrial Fibrillation)2021In: Cardiovascular Electrophysiology, ISSN 1045-3873, E-ISSN 1540-8167, Vol. 32, no 8, p. 2159-2164Article in journal (Refereed)
    Abstract [en]

    AIMS: To assess whether the prevailing rhythm at the time of replying to symptom and health-related quality of life (HR-QoL) questionnaires impacts the findings.

    METHOD: A total of 150 patients from the randomized Catheter Ablation Compared with Pharmacological Therapy for Atrial Fibrillation-trial, comparing atrial fibrillation (AF) ablation versus drugs, were included. The effect of the prevailing rhythm on the outcome results of the HR-QoL 36-Item Short-Form Health Survey, the symptom severity questionnaire (SSQ), and the European Heart Rhythm Association (EHRA) score for classification of AF-related symptoms was assessed.

    RESULTS: AF as the prevailing rhythm was independently associated with a significantly lower Vitality score; 18.4 points lower (95% confidence interval -32.7 to -4.1, p = .01) compared with sinus rhythm when adjusted for AF burden, median duration of episode, number of episodes, beta-blocker use, type of AF, and sex. The presence of AF did not affect the General Health score compared with sinus rhythm, nor did it influence symptoms assessed by the SSQ or EHRA score.

    CONCLUSION: The observation that the presence of AF versus sinus rhythm when conducting HR-QoL tests had a negative impact on its outcome, leaving symptom-related questionnaires unaffected, implies that the prevailing rhythm should be taken into account when results of HR-QoL questionnaires are interpreted.

    QRS dispersion detected in ARVC patients and healthy gene carriers using 252-leads body surface mapping: an explorative study of a potential diagnostic tool for arrhythmogenic right ventricular cardiomyopathy2021In: Pacing and Clinical Electrophysiology, ISSN 0147-8389, E-ISSN 1540-8159, Vol. 44, no 8, p. 1355-1364Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: The diagnosis of ARVC remains complex requiring both imaging and electrocardiographic (ECG) techniques. The purpose was therefore to investigate whether QRS dispersion assessed by body surface mapping (BSM) could be used to detect early signs of ARVC, particularly in gene carriers.

    METHODS: ARVC patients, gene carriers without a history of arrhythmias or structural cardiac changes and healthy controls underwent 12-lead resting ECG, signal-averaged ECG, echocardiographic examination, 24-hours Holter monitoring, and BSM with electrocardiographic imaging. All 252-leads BSM recordings and 12-leads ECG recordings were manually analyzed for QRS durations and QRS dispersion.

    RESULTS: Eight controls, 12 ARVC patients with definite ARVC and 20 healthy gene carriers were included. The ECG-QRS dispersion was significantly greater in ARVC patients (42 vs. 25 ms, p < .05), but failed to fully differentiate them from controls. The BSM-derived QRS dispersion was also significantly greater in ARVC patients versus controls (65 vs. 29 ms, p < .05) and distinguished 11/12 cases from controls using the cut-off 40msec. The BSM derived QRS dispersion was abnormal (> 40 ms) in 4/20 healthy gene carriers without signs of ARVC, which may indicate early depolarization changes.

    CONCLUSIONS: QRS dispersion, when assessed by BSM versus 12-lead ECG, seem to better distinguish ARVC patients from controls, and could potentially be used to detect early ARVC in gene carriers. Further studies are required to confirm the value of BSM-QRS dispersion in this respect.

    Epicardial conduction abnormalities in patients with Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) and mutation positive healthy family members – a study using electrocardiographic imaging2023In: PLOS ONE, E-ISSN 1932-6203, Vol. 18, no 1, article id e0280111Article in journal (Refereed)
    Abstract [en]

    Background: The diagnosis of arrhythmogenic right ventricular cardiomyopathy (ARVC) in early stages is challenging. The aim was therefore to study whether electrocardiographic imaging (ECGI) can detect epicardial depolarization changes in ARVC patients and healthy mutation-carriers (M-carriers).

    Method: Twelve ARVC patients, 20 M-carriers and 8 controls underwent 12-lead ECG, signal-averaged ECG, 2-dimensional echocardiography, 24-hours Holter monitoring and ECGI (body surface mapping and computer tomography with offline analysis of reconstructed epicardial signals). Total and Right Ventricular Activation Time (tVAT and RVAT respectively), area of Ventricular Activation during the terminal 20 milliseconds (aVAte20) and the activation patterns were compared between groups.

    Results: In ARVC patients the locations of aVAte20 were scattered or limited to smaller RV parts versus in controls, in whom aVAte20 was confined to RVOT and LV base (+/- RV base). ARVC patients had smaller aVAte20 (35cm2 vs 87cm2, p<0.05), longer tVAT (99msec vs 58msec, p<0.05) and longer RVAT (66msec vs 43msec, p<0.05) versus controls. In 50% of M-carriers, the locations of aVAte20 were also eccentric. This sub-group presented smaller aVAte20 (53cm2 vs 87cm2, p= 0.009), longer RVAT (55msec vs 48msec, p=0.043), but similar tVAT (65msec vs 60msec, p=0.529) compared with the M-carriers with normal activation pattern.

    Conclusions: The observation of localized delayed epicardial conduction in the RV in M-carriers suggests an early stage of ARVC and may be a useful diagnostic marker enhancing an early detection of the disease.

    Repolarisation abnormalities unmasked with a 252-lead BSM system in patients with ARVC and healthy Gene Carriers2022In: Pacing and Clinical Electrophysiology, ISSN 0147-8389, E-ISSN 1540-8159, Vol. 45, no 4, p. 509-518Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Diagnosing Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) at an early stage can be challenging even after ECG recording and a combination of several imaging techniques. The purpose of this study was to explore if a Body Surface Mapping (BSM) system with 252-leads could identify repolarization abnormalities and thereby diagnose early stages of ARVC.

    METHODS: ARVC patients, gene carriers without signs of ARVC and controls underwent a 12 lead resting ECG, signal-averaged ECG, echocardiography, 24-hours Holter monitoring and BSM with electrocardiographic imaging (ECGI). All 252-leads, divided into four quadrants of the vest, were analyzed regarding concordances between T wave polarity and QRS main vector.

    RESULTS: Of 40 patients included there were 12 ARVC patients, 20 gene carriers and 8 controls. The ARVC patients had two different repolarization patterns, one with more pronounced negative T waves at the lower left panel and another with mixed changes that clearly differed from the controls, all of whom had a normal 12 lead ECGs and consistent repolarization patterns on their BSM recordings. The patterns observed in ARVC patients were also present in 5/20 (25%) gene carriers, three of whom had normal resting ECG. A novel repolarization index successfully detected all ARVC patients and 88% of gene carriers with pathologic repolarization pattern.

    CONCLUSIONS: The finding that abnormal repolarization patterns could be unmasked by BSM in 25% of healthy gene carriers, suggests that it may potentially be a useful tool for identifying early manifestations of ARVC. Further and larger studies are warranted to assess its diagnostic accuracy.

    Preference for oral anticoagulation therapy for patients with atrial fibrillation in Europe in different clinical situations: results of the European Heart Rhythm Association Survey2015In: Europace, ISSN 1099-5129, E-ISSN 1532-2092, Vol. 17, no 5, p. 819-824Article in journal (Refereed)
    Abstract [en]

    The purpose of this European Heart Rhythm Association Survey was to assess the clinical practice in relation to the use of oral anticoagulation therapy for patients with atrial fibrillation (AF) in Europe. Of special interest were patients undergoing percutaneous coronary intervention (PCI), cardioversion procedures, catheter ablation, surgery, and those suffering from anticoagulation-related bleeding. Of 38 responding centres, non-vitamin K antagonist oral anticoagulants (NOACs) were used for stroke prophylaxis and were preferred (33.3%) or considered equal (48.5%) to vitamin K antagonists (VKAs). Only 3% did not use NOACs at all. There were some practice differences regarding the use of NOACs in combination with dual antiplatelet therapy in AF patients undergoing PCI, and only 12% preferred using NOACs in this setting. Bare metal stents were preferred rather than drug-eluting stents in AF patients at high bleeding risk. There were clear practice differences between centres regarding the use of triple therapy. Most of the major bleeding events would be handled using symptomatic and supportive measures (e.g. mechanical compression, fluid replacement, blood transfusion, prothrombin complex concentrate, or recombinant Factor VIIa). More than 80% of the centres offer either VKA or NOAC for at least 3 weeks before and after cardioversion and 70% offer either VKA or NOAC before and after AF catheter ablation. Patients treated with an NOAC were routinely re-assed in most centres.

    The use of wearable cardioverter-defibrillators in Europe: results of the European Heart Rhythm Association survey2016In: Europace, ISSN 1099-5129, E-ISSN 1532-2092, Vol. 18, no 1, p. 146-150Article in journal (Refereed)
    Abstract [en]

    The aim of this European Heart Rhythm Association (EHRA) survey was to collect data on the use of wearable cardioverter-defibrillators (WCDs) among members of the EHRA electrophysiology research network. Of the 50 responding centres, 23 (47%) reported WCD use. Devices were fully reimbursed in 17 (43.6%) of 39 respondents, and partially reimbursed in 3 centres (7.7%). Eleven out of 20 centres (55%) reported acceptable patients' compliance (WCD worn for > 90% of time). The most common indications for WCD (8 out of 10 centres; 80%) were covering the period until re-implantation of ICD explanted due to infection, in patients with left ventricular impairment due to myocarditis or recent myocardial infarction and those awaiting heart transplantation. Patient life expectancy of < 12 months and poor compliance were the most commonly reported contraindications for WCD (24 of 46 centres, 52.2%). The major problems encountered by physicians managing patients with WCD were costs (8 of 18 centres, 44.4%), non-compliance, and incorrect use of WCD. Four of 17 centres (23.5%) reported inappropriate WCD activations in < 5% of patients. The first shock success rate in terminating ventricular arrhythmias was 95-100% in 6 of 15 centres (40%), 85-95% in 4 (26.7%), 75-85% in 2 (13.3%), and < 75% in 3 centres (20%). The survey has shown that the use of WCD in Europe is still restricted and depends on reimbursement. Patients' compliance remains low. Heterogeneity of indications for WCD among centres underscores the need for further research and a better definition of indications for WCD in specific patient groups.

    Cardiac resynchronization therapy pacemaker or cardiac resynchronization therapy defibrillator: what determines the choice?-findings from the ESC CRT Survey II2019In: Europace, ISSN 1099-5129, E-ISSN 1532-2092, Vol. 21, no 6, p. 918-927Article in journal (Refereed)
    Abstract [en]

    AIMS: The decision to implant a cardiac resynchronization therapy pacemaker (CRT-P) or a cardiac resynchronization therapy defibrillator (CRT-D) may be challenging. There are no clear guideline recommendations as no randomized study of cardiac resynchronization therapy (CRT) has been designed to compare the effects of CRT-P with those of CRT-D on patients' outcomes. In the CRT Survey II, we studied patient and implantation centre characteristics associated with the choice of CRT-P vs. CRT-D.

    METHODS AND RESULTS: Clinical practice data from 10 692 patients undergoing CRT implantation of whom 7467 (70%) patients received a CRT-D and 3225 (30%) received a CRT-P across 42 ESC countries were collected and analysed between October 2015 and January 2017. Factors favouring the selection of CRT-P implantation included age >75 years, female gender, non-ischaemic heart failure (HF) aetiology, New York Heart Association functional Class III/IV symptoms, left ventricular ejection fraction >25%, atrial fibrillation, atrioventricular (AV) block II/III, and implantation in a university hospital.

    CONCLUSION: In a large cohort from the CRT Survey II, we found that patients allocated to receive CRT-P exhibited particular phenotypes with more symptomatic HF, more frequent comorbidities, advanced age, female gender, non-ischaemic HF aetiology, atrial fibrillation, and evidence of AV block. There were substantial differences in the proportion of patients allocated to receive CRT-P vs. CRT-D between countries.

    A short P-wave duration is associated with incident heart failure in the elderly: a 15 years follow-up cohort study2022In: Journal of Geriatric Cardiology, ISSN 1671-5411, Vol. 19, no 9, p. 643-650Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Early identification of patients at risk of congestive heart failure (HF) may alter their poor prognosis. The aim was therefore to test whether simple electrocardiographic variables, the P-wave and PR-interval, could predict incident HF.

    METHODS: The PIVUS (Prospective Investigation of the Vasculature in Uppsala Seniors) study (1016 individuals all aged 70 years, 50% women) was used to identify predictors of HF. Subjects with prevalent HF, QRS duration z >= 130 ms, atrial tachyarrhythmias, implanted pacemaker/defibrillator, second- and third-degree atrioventricular block or delta waves at baseline were excluded. Cox proportional hazard analysis was used to relate the PR interval, P-wave duration (Pdur) and amplitude (Pamp), measured in lead V1, to incident HF. Adjustment was performed for gender, RR-interval, beta-blocking agents, systolic blood pressure, body mass index and smoking.

    RESULTS: Out of 836 subjects at risk, 107 subjects were diagnosed with HF during a follow-up of 15 years. In the multivariate analysis, there was a strong U-shaped correlation between Pdur in lead V1 and incident HF (P= 0.0001) which was significant for a Pdur < 60 ms [HR = 2.75; 95% CI: 1.87-4.06, at Pdur 40 ms] but not for prolonged Pdur. There was no significant relationship between incident HF and the PR-interval or the Pamp. A Pdur < 60 ms improved discrimination by 3.7% when added to the traditional risk factors including sex, RR-interval, beta-blocking agents, systolic blood pressure, BMI and smoking (P= 0.048).

    CONCLUSIONS: A short Pdur, an easily measured parameter on the ECG, may potentially be a useful marker of future HF, enabling its early detection and prevention, thus improving outcomes.

    Short P-Wave Duration Is Associated with Incident Atrial Fibrillation: A Registry-Based Cohort Study2022In: International Heart Journal, ISSN 1349-2365, E-ISSN 1349-3299, Vol. 63, no 4, p. 700-707Article in journal (Refereed)
    Abstract [en]

    Atrial fibrillation (AF) is common and increases the risk for stroke and heart failure (HF). The early identification of patients at risk may prevent the development of AF and improve prognosis. This study, therefore, aimed to test the effect of the association between P-wave and PR-interval on the ECG and incident AF. The PIVUS (Prospective Investigation of the Vasculature in Uppsala Seniors) study (1016 individuals all aged 70 years; 50% women) was used to identify whether the ECG variables P-wave duration (Pdur) and PR-duration in lead V1 were related to new-onset AF. Exclusion criteria were prevalent AF, QRS-duration >= 130 milliseconds (msec), atrial tachyarrhythmias and implanted pacemaker/defibrillator. Cox proportional-hazards models were used for analyses. Adjustments were made for gender, RR-interval, beta-blocking agents, systolic blood pressure, body mass index, and smoking. Of 877 subjects at risk, 189 individuals developed AF during a 15-year follow-up. There was a U-shaped relationship between the Pdur and incident AF (P = 0.017) following multiple adjustment. Values below 60 msec were significantly associated with incident AF, with a hazard ratio of 1.55 (95% confidence interval 1.15-2.09) for a Pdur <= 42 msec. There was no significant relationship between incident AF and the PR-interval. A short Pdur derived from the ECG in V1 may be a useful marker for new-onset AF, enabling the early identification of at-risk patients.

    How are European patients at risk of malignant arrhythmias or sudden cardiac death identified and informed about their risk profile: results of the European Heart Rhythm Association survey2015In: Europace, ISSN 1099-5129, E-ISSN 1532-2092, Vol. 17, no 6, p. 994-998Article in journal (Refereed)
    Abstract [en]

    The purpose of this EP wire is to examine clinical practice in the field of screening of patients of risk of ventricular arrhythmias and/or sudden cardiac death (SCD) in European countries. A systematic screening programme existed in the majority of centres and was organized by a multidisciplinary dedicated team or by an activity programme of implantable cardioverter-defibrillator (ICD) or heart failure clinics. In particular, high-risk subgroups of patients with ischaemic and non-ischaemic cardiomyopathy ICD implantation are considered strongly indicated within 90 days of myocardial revascularization or initial diagnosis. Cardiac magnetic resonance imaging appears as an important tool to better characterize the left ventricular arrhythmogenic substrate in patients at risk of SCD.

    Current implantable cardioverter-defibrillator programming in Europe: the results of the European Heart Rhythm Association survey.2014In: Europace, ISSN 1099-5129, E-ISSN 1532-2092, Vol. 16, no 6, p. 935-938Article in journal (Refereed)
    Abstract [en]

    The purpose of this European Heart Rhythm Association (EHRA) survey was to examine the current practice on the choice of implantable cardioverter-defibrillator (ICD) type, use of defibrillation testing, and ICD programming for detection and therapy of ventricular arrhythmias. In accordance with recent guidelines and the results of observational studies, the majority of EHRA research network centres reported a high utilization rate of dual-chamber ICDs in the presence of symptomatic and asymptomatic sinus node dysfunction, biventricular ICD in high-degree atrioventricular block and QRS duration <120 ms, and a limited use of defibrillation testing either in primary and secondary prevention settings. Activation of the long ventricular tachycardia (VT) detection window, slow VT zone, antitachycardia pacing before shock for slow and fast VT, and atrial tachyarrhythmia discrimination were considered useful in ICD programming for the majority of patients.

    Cardiac Resynchronization Therapy Optimization: Comparison and Evaluation of Non-invasive Methods2012Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The general purpose of this thesis was to investigate new cardiac resynchronization therapy (CRT) optimization techniques and to assess their reliability when compared to invasive measurements of left ventricular contractility (LV dP/dtmax).We first assessed whether cardiac output (CO) measured by trans-thoracic impedance cardiography could correctly identify the optimal interventricular (VV) pacing interval while using invasive measurements of LV dP/dtmax as reference. We did not find any significant statistical correlation between the two optimizing methods when their corresponding optimal VV intervals were compared.

    We also tested the hypothesis that measurements of right ventricular contractility (RV dP/dtmax) could be used to guide VV delay optimization in CRT. The comparison of optimal VV intervals obtained from the left and right ventricular dP/dtmax did not show a statistically significant correlation; however, a positive correlation was found when broader VV intervals were evaluated and we concluded that this finding deserves further investigation.

    An interesting alternative for CRT optimization is the use of device integrated algorithms or sensors capable to adapt the CRT settings to the current needs of the individual patient. In this respect we investigated the use of cardiogenic impedance (CI) measurements obtained through the CRT-D device as a method for CRT optimization with invasive measurements of LV dP/dtmax as a reference. Our results showed that CI could be measured through the device after implantation and that a patient-specific impedance-based prediction model was capable to accurately predict the optimal AV and VV delays. To follow up on these positive results we re-evaluated the patient-specific impedance-based prediction models 24 hours post implantation and investigated the possibility of calibrating them using parameters derived from non-invasive measurements of arterial pressure obtained by finger pelthysmography at implantation.The results showed that the patient-specific impedance-based prediction models did not perform as well on the follow-up data as they did on the data from implantation day and that they correlated poorly with plethysmographic parameters.

    Our studies suggest that novel methods for CRT optimization should be thoroughly evaluated and compared to established measures of left ventricular function prior to introduction into clinical practice.

    Abstract [en]

    The present study aimed to assess whether impedance cardiography (IC) can correctly identify the optimal interventricular (VV) pacing interval in cardiac resynchronization therapy (CRT). Twenty four patients received a biventricular pacemaker and underwent IC for cardiac output (CO) measurements to identify the optimal VV interval. Invasive measurements of left ventricular (LV) dP/dt(max) were used as a reference. During optimization the VV interval was changed with 20 ms steps from +80 (LV pre-excitation) to-80 ms (RV pre-excitation). The optimal VV interval was defined as the one that resulted in the highest LV dP/dt(max) value and the highest CO obtained by IC, respectively. During simultaneous biventricular pacing both LV dP/dt(max) and CO increased (mean 16.6% and 16.2%, respectively) as compared to baseline. Biventricular pacing with optimized VV intervals resulted in a further absolute increase of LV dP/dt (max) and CO (5.6% and 41.3%, respectively). The average decrease in LV dP/dt(max) was 79.6 +/- 51.6 mmHg/s when the optimal VV interval was programmed according to the IC measurements. Cross spectral analysis showed no correlation between the optimal VV intervals identified by the two methods (p > 0.05) and identical optimal VV intervals were identified in only six of the 24 patients. When broader VV time intervals were compared the correlation between the two methods was statistically significant (p = 0,0166). In conclusion, the use of IC for VV interval optimization is questionable since these optimized time intervals do not seem to correlate well with those obtained by measuring LV dP/dt.

    Abstract [en]

    AIMS: The aim of the present study was to assess whether right ventricular (RV) contractility can be used for optimization of the interventricular (VV) interval and to study the acute hemodynamic effect of different VV intervals on right and left ventricular (LV) contractility in patients referred for cardiac resynchronization therapy (CRT). METHODS AND RESULTS: Intracardiac LV and RV dP/dt were measured with a 0.014-in. sensor-tipped pressure guidewire during pacing at nine different VV intervals ranging from +80 ms (LV pre-excitation) to -80 ms (RV pre-excitation) in 26 patients who received a biventricular pacemaker. No correlation was found between the optimal VV intervals identified by maximum LV dP/dt and RV dP/dt, which were identical in only seven cases (27%). Only when testing slightly broader intervals (+/-20 ms) was there a statistically significant correlation (P= 0.037) between the optimized VV intervals. In the majority of patients (58%) either LV or RV pre-excitation was superior to simultaneous pacing according to LV dP/dt(max) measurements. CONCLUSION: RV dP/dt(max) failed to identify the optimal VV interval when compared with LV dP/dt(max) and can therefore not be recommended for VV optimization in CRT patients.

    Abstract [en]

    Aims Cardiac resynchronization therapy (CRT) has dramatically improved the symptoms and prognosis of patients with heart failure in large randomized clinical trials. Optimization of device settings may maximize benefit on an individual basis, although the best method for this is not yet established. We evaluated the use of cardiogenic impedance measurements (derived from intracardiac impedance signals) in CRT device optimization, using invasive left ventricular (LV) dP/dt(max) as the reference. Methods and results Seventeen patients underwent invasive haemodynamic assessment using a pressure wire placed in the LV cavity at the time of CRT device implantation. Intracardiac impedance measurements were made at different atrioventricular (AV) and interventricular (VV) delays and compared with LV dP/dt(max). We assessed the performance of patient-specific and generic impedance-based models in predicting acute haemodynamic response to CRT. In two patients, LV catheterization with the pressure wire was unsuccessful and in two patients LV lead delivery was unsuccessful; therefore, data were acquired for 13 out of 17 patients. Left ventricular dP/dt(max) was 919 +/- 182 mmHg/s at baseline and this increased acutely (by 24%) to 1121 +/- 226 mmHg/s as a result of CRT. The patient-specific impedance-based model correctly predicted the optimal haemodynamic response (to within 5% points) for AV and VV delays in 90 and 92% of patients, respectively. Conclusion Cardiogenic impedance measurements are capable of correctly identifying the maximum achievable LV dP/dt(max) as measured by invasive haemodynamic assessment. This study suggests that cardiogenic impedance can potentially be used for CRT optimization and may have a role in ambulatory assessment of haemodynamics.

    Aims

    Encouraging data have been reported on the use of cardiogenic impedance (CI) in cardiac reshynchronization therapy (CRT) optimization. The purpose of this study was to: evaluate the stability of certain CI vectors 24 hours post implantation, study the correlation between these CI signals and selected echocardiographic parameters, examine the possibility of non-invasive calibration of patient-specific impedance-based prediction models.

    Methods and results

    Thirteen patients received a CRT-D device with monitor capability of the dynamic impedance between several electrodes. At implantations patient-specific impedance-based prediction models were created for identification of optimal atrioventricular (AV) and interventricular (VV) delays and calibrated on invasive measurements of left ventricular contractility (LV dP/dtmax). Simultaneously non-invasive measurements of LV dP/dtmax and stroke volume (SV) were obtained using a finger plethysmograph. Patients were re-evaluated with echocardiography and new CI measurements the day after implantation.The haemodynamic benefit achieved by optimal VV setting according to the patient-specific impedance-based prediction models at follow-up was not as large as the one obtained at implantation. In a multivariate partial least square regression analysis a correlation was found between aortic VTI and a generic linear combination of CI features (P<0,005). No correlation was found between the patient-specific impedance-based prediction models and the non-invasive measurements of LV dP/dtmax and SV.

    Conclusions

    Cardiogenic impedance signals can be used to optimize CRT settings but seems less feasible as an ambulatory tool since calibration is required. The positive correlation between aortic-VTI and CI measurements seems promising; although a larger cohort is required to create an echocardiography-based patient-specific model.

    Use of event recorders and loop recorders in clinical practice: results of the European Heart Rhythm Association Survey2014In: Europace, ISSN 1099-5129, E-ISSN 1532-2092, Vol. 16, no 9, p. 1384-1386Article in journal (Refereed)
    Abstract [en]

    Several kinds of electrocardiogram monitoring systems are now available in the clinical practice. The aim of this European Heart Rhythm Association (EHRA) survey was to assess the use of different monitoring techniques in the evaluation of patients with unexplained syncope, palpitations, and in those with established diagnosis of atrial fibrillation. Forty-five centres in Europe answered the questionnaire and the majority (78%) were university hospitals. The answers showed a discrepancy between the recommended use of implantable loop recorders (ILRs) in patients with unexplained syncope and the use of this device in clinical practice. In most of the cases only a minority of patients (<20%) seemed to actually receive an ILR as a part of the diagnostic process in accordance to the current guidelines. Holter monitoring systems and external loop recorders seemed to be the preferred monitoring techniques both in patients with recurrent palpitations and in those with established diagnosis of atrial fibrillation.

    Do cardiologists follow the European guidelines for cardiac pacing and resynchronization therapy?: Results of the European Heart Rhythm Association survey2015In: Europace, ISSN 1099-5129, E-ISSN 1532-2092, Vol. 17, no 1, p. 148-151Article in journal (Refereed)
    Abstract [en]

    The purpose of this European Heart Rhythm Association (EHRA) EP wire survey was to evaluate the implementation of the current guidelines for cardiac pacing and cardiac resynchronization therapy (CRT) in Europe. A total of 48 centres replied to the survey, 34 of them (71%) were university hospitals. All responding centres implement CRT in patients with classical indications, i.e. sinus rhythm, New York Heart Association (NYHA) functional class II, III, or ambulatory IV, left ventricular ejection fraction (LVEF) 35%, and left bundle-branch block (LBBB) with QRS duration >150 ms, while 31 centres (67%) would implant a CRT device in patients with the same characteristics but with a non-LBBB pattern. Forty-one centres (89%) would also implant CRT in patients with sinus rhythm, NYHA Class II, III, or ambulatory IV, LVEF <35%, and LBBB with QRS duration between 120 and 150 ms, while only eight centres (17%) would implant the device in patients with the same characteristics but with a non-LBBB pattern. In patients with LVEF <35% and QRS duration below 120 ms, the majority of the centres (80%) would implant a single- or dual-chamber implantable cardioverter-defibrillator, but in nine cases (20%) no device was considered to be indicated. The results of this survey showed a good adherence to some of the current recommendations. Still some reluctance exists when offering the device therapy to patients with QRS duration in the lower range.

    Contemporary practice of CRT implantation in Scandinavia compared to Europe2019In: Scandinavian Cardiovascular Journal, ISSN 1401-7431, E-ISSN 1651-2006, Vol. 53, no 1, p. 9-13Article in journal (Refereed)
    Abstract [en]

    Objectives: To compare the contemporary practice of CRT implantation in Scandinavia and Europe.

    Design: We used data from The European CRT Survey II to highlight similarities and differences in the practice of CRT implantation between Europe (EUR) and Scandinavia (SCAND) and between the Scandinavian countries Denmark, Norway and Sweden. Implant data from the national pacemaker registries were used to calculate coverage.

    Results: The coverage was 24% in SCAND and 11% in EUR. SCAND patients were more often referred from another centre and follow-up was less often to be performed at the operating centre. Telemonitoring was more commonly used. More patients had AV-block or pacemaker dependency/expected high RV pacing percentage as indication for CRT. A CRT-P was more commonly used, and ischaemic aetiology was slightly less common. Echocardiography was more often used to determine LVEF, as well as occlusive venography and placing the RV lead first. In DK implanters tended to choose a septal RV position. Quadripolar leads were more often and a test shock less often used. The paced QRS duration was slightly longer and the narrowing of QRS with CRT more limited. Procedure times and preoperative LVEF were similar.

    Conclusions: In Scandinavia AV-conduction disturbance and/or a ventricular pacing indication was a more common indication for CRT, suggesting adaptation of the most recent guidelines ahead of their publication. A test shock was almost never performed, in agreement with recent scientific evidence. CRT-P was more often used, the procedures seem more centralized and quadripolar leads were preferred.

    Abstract [en]

    Cardiac device implantation is the most common of all invasive cardiac electrophysiological procedures. Over 250 000 devices are implanted each year in Europe. The purpose of this European Heart Rhythm Association (EHRA) survey was to assess the facilities, personnel, and protocols of members of the EHRA electrophysiology (EP) research network involved in device implantation. There were 68 responses to the questionnaire. The survey responses were mainly (84%) from medium- to high-volume device implanting centres, performing >200 implants per year, with over 50% performing >400 implants per year. Most consultants are male (85%), half of all centres had no female consultants, and only one in six had more than one female consultant. There is trend towards specialization in device implantation. The combination of device implantation and EP is still common (76% of all centres) but only 34% of centres have consultants performing device implantation and coronary intervention. Moreover, 23% of centres have all device implantation performed by consultants who do not perform any other types of procedure. Cardiac device implantation as a day case is the planned admission for routine elective device implantation in 30% of hospitals, 47% of hospitals have a single night stay, and 23% of hospitals have admission durations of two or more nights. Device implantation is available as a 24 h service, 365 days a year in 38% of hospitals. The commonest other model was as a daytime service on weekdays in 45% of hospitals.
