Factors affecting mitral valve reoperation in 317 survivors after mitral valve reconstruction

摘要: Abstract From a very heterogeneous group of 340 patients undergoing mitral valve reconstruction from 1969 through 1988, 313 hospital survivors were analyzed for factors affecting the occurrence reoperative procedures related to native dysfunction. Follow-up was 100% and extended 1 year 20 years (mean follow-up, 7.2 years). Sixty-three (18.5% 340) required reoperation at mean postoperative interval 6 (range, 15 Incremental risk event late failure included age, sex, preoperative New York Heart Association class, cause valvular disease, pathophysiology valve, previous operation, pathology, estimation function operation after repair.
