title: [Aortic valve replacement in persons over 75. 128 operated patients].
abstract: Aortic valve replacements are performed in ever older subjects. In the surgical cardiovascular clinic of Rennes, 128 patients aged 75 or over (up to 85 years) and presenting with solitary or predominant (126 cases) aortic stenosis underwent aortic valve replacement between 1976 and 1985 inclusive. Pre-operative evaluation consisted, on principle, of non-invasive explorations. Myocardial protection was ensured by hypothermic cardioplegia. We used a mechanical (Björk-Shiley) prosthesis in the 19 patients operated upon before 1980, and a bioprosthesis (Carpentier-Edwards porcine, supra-annular type since 1983), in the 109 patients operated upon since 1980. The operative mortality rate was 8.6% (11 deaths). The survival curve was similar to that of a control population of the same age-group (survivors 75% at 4 years, operative mortality included). The quality of survival was remarkable since 96% of survivors were in NYHA stages I or II, the poor results being due to early or late cerebral vascular accidents. Advances in surgery (notably myocardial protection), anaesthesia and intensive care make it possible reasonably to operate upon very old patients, provided they have remained in good general and cerebral vascular condition. Non-surgical alternatives, such as percutaneous valvuloplasty, now used in elderly patients can only be reliable if results of similar quality and durability can be expected from them.
