Durability of Mitral Valve Repair for Degenerative Mitral Regurgitation

A large, single-center, contemporary long-term follow-up of degenerative mitral valve disease patients undergoing mitral valve repair surgery has shown that 30-day post-operative mortality is < 1% and a median almost nine-year follow-up survival is 90%. Somewhat worse outcomes were observed in those with preoperative symptoms, reduced left ventricular function, atrial fibrillation, and isolated anterior leaflet disease.
