Between May 1964 and November 1986, 70 patients underwent aortic valve replacement with (20%) or without (80%) additional surgical procedures. Most of the prosthetic devices were Starr-Edwards models and Björk-Shiley and Sorin tilting disks. Long-term follow-up (305 patient years) was assessed in 65 patients who survived the operation. Actuarial survival was 85 +/- 2% at 5 years and 72 +/- 6% at 20 years. The linearized rate of deaths occurring greater than 30 days postoperatively was 3.6% per patient year; sudden death was the most frequent cause of death. Preoperative functional capacity class significantly influenced the immediate outcome of surgery. Although the incidence of prosthetic valve-related complications was higher than in previous studies, survival rates were comparable.
1964年5月至1986年11月期间，70例患者接受了主动脉瓣置换术，其中20%（即14例）同时接受了其他外科手术，80%（即56例）未接受其他外科手术。大多数人工瓣膜为斯塔尔-爱德华兹型号以及比约克-希利和索林倾斜碟瓣。对65例术后存活的患者进行了长期随访（共305患者年）。5年时的精算生存率为85±2%，20年时为72±6%。术后30天以上发生死亡的线性化发生率为每年3.6%；猝死是最常见的死亡原因。术前功能能力分级对手术的近期结果有显著影响。虽然人工瓣膜相关并发症的发生率高于以往研究，但生存率相当。
