Aortic valvular replacement in octogenarians. Short-term and mid-term results in 140 patients

Aortic valvular replacements were performed between 1986 and 1995 at Rouen University Hospital on 140 octogenarians (52 male and 88 female). Pure or predominant aortic stenosis was present in 115 patients, 25 had associated aortic stenosis and insufficiency or predominant aortic insufficiency. Significant coronary lesions were present in 42% of patients. An isolated aortic valvular replacement was performed in 74% of patients, associated with a bypass in 23% and a bioprosthesis was used in 90%. Valvular lesions were mainly caused by Monckeberg disease. Thirteen operative deaths occurred (9.3%). Functional recovery was satisfactory in 78%, mean hospital stay was 12 days. All well-known risk factors for aortic valvular replacement: age, coronary lesions, cardiac insufficiency, impaired ejection fraction and aortic insufficiency, led to an increase in operative mortality but were not statistically significant. Late mortality occurred in 28 patients, 99 patients are still alive at 4-91 months after surgery, The actuarial survival curve shows a 56.5% probability of surviving 5 years. Eighty per cent of survivors are able to live independently at home. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.
