Comparisons between the outcome of mitral repair versus replacement in patients with ischemic heart disease with severe ischemic mitral regurgitation and undergoing coronary artery bypass grafting (CABG) surgery: Review article

Abstract

Ischemic mitral regurgitation (IMR) is a complication that frequently happens following myocardial infarction (MI). Around fifty percent of cases develop IMR following MI, and more than ten percent of them have moderate or severe IMR. A poor prognosis is predicted by the presence of IMR. Previous research has demonstrated a higher severity of IMR related to a shorter long-term survival. The mortality rate of cases with even mild IMR is 17% higher than that of those without it. The most effective operation for moderate ischemic mitral regurgitation with concomitant coronary Artery Disease (CAD) is also a topic of controversy. In retrospective research, we investigated the real-world operational results of cases having CAD and ischemic mitral regurgitation who underwent mitral valve surgeries and concomitant coronary artery bypass grafting. An elevated surgical mortality rate and poor long-standing survival are related to the ischemic mitral regurgitation operational management.
