A comparison of outcomes of mitral valve repair for degenerative disease with posterior, anterior, and bileaflet prolapse

摘要: Objective We sought to compare the clinical and echocardiographic outcomes of mitral valve repair for regurgitation in patients with degenerative disease posterior, anterior, or bileaflet prolapse. Methods Patients underwent operations from 1981 through 2001: 359 had posterior (mean age, 60.4 years), 92 anterior 53.3 250 (means 56.4 years) prolapse were younger (P = .04) more associated aortic .02), particularly bicuspid Results The overall survival at 12 years was 75% ± 5%, no difference among groups .3). freedom reoperation 96% 2% 88% 4% 94% .019). Anterior only independent predictor reoperation. moderate severe 80% 65% 8% 67% 6% .001). prolapse, ejection fraction less than 40%, predictors recurrent regurgitation. Conclusions pathophysiology affects durability disease, results are better those This study indicates that rates underscore failure repair.
