Abstract [en]

Objectives. To compare valve-related morbidity among patients aged = 70 years, receiving either a mechanical or a biological prosthesis in a population-based setting. Design. In total, 3279 patients (21 644 patient-years) were followed up through the Swedish National In-Patients Register, which registers all hospital admissions. Death, thromboembolism, bleeding, endocarditis, valve thrombosis and reoperations were all captured. Results. Survival was lower among patients aged 5 years). Event-free survival was higher in younger patients with a mechanical prosthesis compared to bioprosthesis recipients (p < 0.001), but equal among older patients. Conclusions. Survival was comparable in older patients irrespective of prosthesis type. Bleeding was increased with a mechanical prosthesis, especially in the elderly. The risk of thromboembolism was higher in patients with a bioprosthesis.
