Surgical treatment of mitral valve insufficiency by valve repair

OBJECTIVE: To analyze the short term results of mitral valve repair in a consecutive series of mitral insufficiency patients from different ethiologies. METHODS: A retrospective study was made of 86 patients with mitral insufficiency operated on between May 1992 and May 2001 for mitral valve repair. Mitral insufficiency was severe in 77 patients and moderate in 9. The functional class of the patients was I in 4, II in 48, III in 29 and IV in 5 patients. The etiology was rheumatic in 47 (54.6%) cases. RESULTS: Mitral valve repair was performed by only one procedure on the mitral valve in 6 patients, two procedures in 29, and three or more procedures in 51 (59.3%) patients. Mitral annuloplasty was performedin 81 patients, with the Braile posterior pericardial ring being the mostcommonly used (87.2%). Hospital mortality was 3.5%. There was improvement in the funcional class in 79 (91.8%) patients. Mitral valve function was normal in 80 (93%) patients and moderate mitral insufficiency occurred in 6 patients. CONCLUSION: Mitral valve repair can be performed with low mortality (3.5%) and high probability of valve function recovery (93%). It should be the procedure of choice in patients with mitral insufficiency.
