Mitral Valve Replacement Is a Viable Alternative to Mitral Valve Repair for Ischemic Mitral Regurgitation: A Case-Matched Study

Mitral valve replacement remains a viable option for the treatment of IMR. Although mitral valve repair effectively protects against persistent or recurrent moderate-to-severe MR, mitral valve replacement provides better freedom from mild-to-moderate MR in this population, with a low incidence of valve-related complications. Notably, there was no significant difference in left ventricular function between the valve-repair and valve-replacement groups at follow-up.
