Emerging evidence indicates that etiology plays an essential role in the results of mitral valve repair. In this study we examined the long-term performance of this procedure in 66 consecutive patients with pure rheumatic mitral insufficiency. Patient ages ranged from 4 to 76 years (mean: 52.7 ± 15). Preoperatively, 94.6% of the patients were in NYHA class II or III. There was no hospital mortality. By actuarial methods 95,5% of the patients were alive 8 years postoperatively, and 84,1% were reoperation free. Freedom from reoperation was significantly higher in patients who received a prosthetic ring than in those who had other types of anuloplasty (96.7% vs 59.3%; p = 0.001). In our series, in contrast with the literature, there was no relationship between valve failure and age at the time of the operation. There were only two cases of thromboembolism and one case of infective endocarditis. This study confirms that mitral valve reconstruction in rheumatic valve insufficiency is feasible with satisfactory long-term clinical results, which are suboptimal compared with those obtained in patients with degenerative disease. The favourable results depend on a routine use of a prosthetic ring and on an adequate patient selection. Attention should be directed toward improved detection and suppression of rheumatic activity at the time of operation.
