229 patients aged 70 or over with aortic stenosis (AS) underwent surgery between January 1972 and July 1983 (21.8% of 814 cases of AS operated on during the same period). The Björk Shiley prosthesis was used at the beginning of the series (115 cases, 50.2%), until bioprostheses became the treatment of choice in this age group. Overall operative mortality in the series was 10.9% (25/229). Analysis shows a very marked reduction in recent years: from 15.6% between 1972 and 1977, to 5.8% in 1982-3. Improvement can be attributed in part to the technical progress in myocardial protection. Patient age is a very significant factor in the prognosis. Progress in surgery, together with that in anaesthetics and intensive care, justifies operation in these elderly and incapacitated patients whose general and neurological condition is well preserved.
1972年1月至1983年7月期间，229例70岁及以上的主动脉瓣狭窄（AS）患者接受了手术（占同期814例AS手术病例的21.8%）。该系列研究开始时使用的是比约克·希利人工瓣膜（115例，占50.2%），直到生物瓣膜成为该年龄组的首选治疗方式。该系列研究的总体手术死亡率为10.9%（25/229）。分析表明，近年来手术死亡率显著下降：从1972年至1977年的15.6%降至1982 - 1983年的5.8%。这种改善部分归因于心肌保护技术的进步。患者年龄是预后的一个非常重要的因素。外科手术的进展，以及麻醉和重症监护方面的进展，使得对这些一般状况和神经状况良好的老年体弱患者进行手术成为合理选择。
