Between July 1970 and June 1977, 151 patients underwent isolated mitral valve replacement with the Björk-Shiley valve. The follow-up period extended over 8 years to June 1978. Hospital mortality was 5.2% (8/151), late mortality 8.4% (12/143). Actuarial survival analysis predicts 84 (+/- 4) % of patients to be alive at 5 years and 80 (+/- 6) % at 8 years. Thirteen patients sustained 15 episodes of thromboembolic complications; actuarially 88 (+/- 4) % of patients were free from this complication at 5 years and 81 (+/- 8) % at 8 years. Other valve-related complications included paravalvular leak (7), prosthetion showed an improvement of at least one class in 84% of patients.
1970年7月至1977年6月期间，151例患者接受了使用Björk-Shiley瓣膜的单纯二尖瓣置换术。随访期延长至8年，至1978年6月。医院死亡率为5.2%（8/151），晚期死亡率为8.4%（12/143）。精算生存分析预测，5年时84（±4）%的患者存活，8年时80（±6）%的患者存活。13例患者发生了15次血栓栓塞并发症；精算显示，5年时88（±4）%的患者无此并发症，8年时81（±8）%的患者无此并发症。其他与瓣膜相关的并发症包括瓣周漏（7例），84%的患者心功能至少改善了一级。
