Introduction: Mitral valve Replacement and repair are competitive therapeutic modalities in treatment of severe MR. Based on background clinical literature we hypothesized that mitral valve repair will have survival benefit in short and long term follow up. We are comparing the long term results of mitral valve replacement or repair combined with tricuspid valve repair.
Patients: Between 1994 and 2013, 312 patients underwent concomitant mitral and tricuspid procedures in our institution. Of these 199 (64%) underwent mitral valve replacement and 113 (36%) underwent mitral valve repair.
Results: The groups were similar with respect to age, presence of CHF, left ventricular function and co-morbid conditions. More patients in the replacement group were in atrial fibrillation (64% vs. 45%, p=0.001). All patients in the repair group had mitral regurgitation of moderate or greater degree vs. 91% in the replacement group (p=0.0004). 19% and 35% underwent concomitant coronary bypass in the replacement and repair groups respectively (p=0.002). Logistic EuroSCORE was 12±14 and similar between groups. The operative mortality was 12% (n=38) and similar between groups. Survival at 1,3, and 5 years was also similar between groups.
Conclusions: There was no long time survival benefit in mitral valve repair as oppose to replacement, when it is combined with tricuspid valve repair.
