Does mitral valve repair with an undersized, flexible annuloplasty ring improve survival and symptoms in patients with cardiomyopathy and severe mitral regurgitation?
Mitral valve repair with an undersized annuloplasty ring is a safe and effective strategy that promotes reverse remodeling and improves symptoms in patients with end-stage cardiomyopathy and severe mitral regurgitation.
Badhwar et al. (2002) conducted a cohort in Cardiomyopathy and severe mitral regurgitation (n=150). Mitral valve repair with an undersized, flexible annuloplasty ring was evaluated on 5-year actuarial survival rate. Mitral valve repair with an undersized, flexible annuloplasty ring in patients with cardiomyopathy and severe MR achieved 1-, 2-, and 5-year survival rates of 82%, 71%, and 57%, respectively.
