One hundred and twenty two patients with mitral regurgitation grade 3-4 underwent surgery for mitral valve repair with annuloplasty ring. Patient age was 65+/-10 and 89 (73%) were male. Eighty-six (70%) were in NYHA class III-IV, 77 (63%) had reduced LV function, and mean MR grade (+/-SD) was 3,8+/-0,4. One hundred and thirteen operative survivors were followed for 33 months in average. Overall MR grade improved and was 1,6+/-1. Twenty-eight patients (25%) remained with MR grade 3-4. Survival was 70% at 5 years. Predictors for late mortality were LV function, NYHA class IV, and older age. Residual MR did not emerge as a predictor for late mortality.
