Mitral-Valve Repair versus Replacement for Severe Ischemic Mitral Regurgitation

Abstract

We observed no significant difference in left ventricular reverse remodeling or survival at 12 months between patients who underwent mitral-valve repair and those who underwent mitral-valve replacement. Replacement provided a more durable correction of mitral regurgitation, but there was no significant between-group difference in clinical outcomes.
