Surgical and late follow-up results were compared between 40 elderly patients over 70-years-old (group I) and 43 patients aged from 65 to 69-years-old (group II) with acquired valvular heart disease. There was one hospital death in group I, and two hospital deaths in group II. There was no difference between group I and group II in the rate of hospital mortality of the occurrence of the surgical complications. Postoperative respiratory failure did not occur even in the elderly patients with preoperatively impaired vital capacity (%VC below 60%). Postoperative cardiac function after aortic valve replacement for aortic stenosis in elderly patients more significantly improved in comparison with preoperative function. Survival rate was 62% in group I and 78% in group II from actual survival curve at 9 year after surgery by Kaplan-Meier method. Late survival rate and cardiac event free rate were not significantly different between group I and II. Surgical results in elderly patients with valvular heart disease were satisfactory.
对40例70岁以上的老年患者（I组）和43例65至69岁的患者（II组）的后天性心脏瓣膜病手术及后期随访结果进行了比较。I组有1例医院死亡，II组有2例医院死亡。I组和II组在手术并发症发生率的医院死亡率方面没有差异。即使是术前肺活量受损（%VC低于60%）的老年患者也未发生术后呼吸衰竭。老年患者主动脉瓣狭窄行主动脉瓣置换术后的心功能较术前有更显著改善。采用Kaplan-Meier法，术后9年实际生存曲线显示I组生存率为62%，II组为78%。I组和II组的晚期生存率和无心脏事件发生率无显著差异。老年心脏瓣膜病患者的手术结果令人满意。
