What is Mitral valve repair: Results and the decision-making process in reconstruction about?

patients underwent mitral valve repair for mitral regurgitation, pure (148 patients) or associated with mitral stenosis (127 patients). Patients with pure mitral stenosis were excluded from this study. The cause of mitral regurgitation was rheumatic in 180 patients (aged 28.6 ± 1.2 years, mean ± standard error of the mean) and degenerative in 84 patients (aged 54.7 ± 1.5 years). Fifty-nine percent of the patients were in New York Heart Association classes ill and IV before the operation. Intraoperative assessment of the mitral valve led us to identify four major mechanisms of mitral regurgitation: (1) restriction of leaflet motion by fibrosis (group I, 63 patients); (2) enhancement of leaflet motion by leaflet and chordal extension and prolapse (group II, 139 patients), (3) combination of both (group ill, 64 patients); and (4) isolated dilatation of the anulus (group IV, 10 patients). One hundred sixty-one patients had isolated mitral disease and 114 had associated aortic or tricuspid valve disease, or both. The hospital mortality rate was 4.0 %. FoUow-up was 96 % complete and totaled 1247.47 patient-years. At 13 years' foUow-up, the survival rate was 93.0% ± 6.8% in group I, 90.0
