Mitral valve repair following heart attack may offer patients little to no benefit: Routinely adding mitral valve repair to coronary artery bypass graft surgery for heart attack patients may not be warranted in patients with moderate mitral valve damage

Mitral valve repair following heart attack may offer patients little to no benefit: Routinely adding mitral valve repair to coronary artery bypass graft surgery for heart attack patients may not be warranted in patients with moderate mitral valve damage, according to an NIH-funded study. Patients treated with both procedures versus the bypass graft alone showed no differences at one year in recovery from structural damage to the heart’s left ventricle, nor in secondary measures such as heart failure, stroke, functional status or quality of life. The results of the Surgical Interventions for Moderate Ischemic Mitral Regurgitation (IMR) study, supported by NIH’s National Heart, Lung, and Blood Institute (NHLBI), were presented at the American Heart Association Scientific Sessions in Chicago and published simultaneously in the New England Journal of Medicine.
