Moderate to severe ischemic mitral regurgitation: More data to guide the choice. Why not consider the use of subvalvular repair?

摘要

In a recent issue of Cardiology Journal, Li et al. [1]described long-term outcomes of mitral valve surgery in patients with ischemic mitral regurgitation(MR). Using a propensity-score matched analysiswith 77 pairs of patients and a median follow up of53 months, their results indicate that subvalvularsparing mitral valve replacement leads to reducedhospitalization for heart failure and improvedventricular remodeling, with no differences in mortality. This study encourages scientific debate onthis topic as an optimal treatment in patients withischemic MR, which is far from being established.
