Moderate ischemic mitral regurgitation in ischemic heart disease: to operate or not? A meta-analysis.

Introduction: Deciding whether to perform coronary artery bypass grafting (CABG) alone or in combination with mitral valve repair is a common dilemma encountered by surgeons when treating patients with ischemic mitral regurgitation, a common condition related to coronary artery disease. Although ischemic mitral regurgitation after CABG has been linked to unfavorable results, the benefits of including mitral valve repair are still unknown. This discrepancy led us to undertake a systematic review and meta-analysis to determine whether combining CABG with mitral valve surgery leads to better clinical results than CABG alone.
