Aortic Valve Selection in the Elderly Patient

摘要: Abstract To determine the influence of valve selection on valve-related morbidity and mortality patient survival, comparative long-term performance characteristics mechanical (N = 68) bioprosthetic 73) heart valves were analyzed for 141 patients more than 70 years old who underwent isolated aortic replacement between 1970 1985. Cumulative follow-up was 491 patient-years (average, 4.3 per patient). Hospital 18% 19% with valves, respectively. Survival at 5 61 ± 7% (± standard error) 67 10% recipients Male sex ( p 0.014) urgency operation 0.006) independent risk factors hospital mortality. Atrial fibrillation increased 0.01). No required reoperation or experienced structural failure. While anticoagulant-related hemorrhage in (9.2 2.1%/patient-year) compared (2.3 1.1%/patient-year), it did not result a death lead to permanent disability. There no difference freedom from any complication years. However, when all morbid events are considered, fewer complications receiving (10.7 2.3%/patient-year versus 17.6 2.5%/patient-year, respectively;
