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 analysis with 77 pairs of patients and a median follow up of 53 months, their results indicate that subvalvular-sparing mitral valve replacement leads to reduced hospitalization for heart failure and improved ventricular remodeling, with no differences in mortality. This study encourages scientific debate on this topic as an optimal treatment in patients with ischemic MR, which is far from being established.
