Abstract: Introduction: The long-term results after surgical repair of rheumatic mitral valve remain controversial in literature. Our aim was to determine the predictive factors which impact the long-term results after isolated rheumatic mitral valve repair and to evaluate the effect of those factors on reoperation and late mortality. Methods: One hundred and four patients with rheumatic valve disease who had undergone mitral valve repair with or without tricuspid valve annuloplasty were included. All patients with associated procedures were excluded. The predictive variables for reoperation were assessed with Cox regression and Kaplan Meier survival curves. Results: The mean follow-up time was 63 ± 39 months (CI 95% 36 to 74 months). The functional class III and IV was observed in 65.4% of all patients. The posterior ring annuloplasty was performed in 33 cases, comissutoromy in21 cases, and comissurotomy with posterior ring annuloplasty in 50 patients. There was no operative mortality. The late mortality was 2.8% (three patients). The late reoperation was associated with residual mitral valve regurgitation after surgery (P<0.001), pulmonary hypertension at the preoperative time (P<0.001), age (P<0.04) and functional class at the post-operative time (P<0.001). We observed freedom from reoperation rates at 5 and 10 years of 91.2 ± 3.4% and 71.1 ± 9.2%, respectively. Conclusion: Repair of mitral valve in rheumatic valve disease is feasible with good long-term outcomes. Preoperative pulmonary hypertension, residual mitral valve regurgitation after surgery, age and functional class are predictors of late reoperation.
