The importance of grade 2 ischemic mitral regurgitation in coronary artery bypass grafting

Abstract

CABG on patients with grade 2 ischemic MR reduces angina pectoris and improves functional status to the same extent as in CABG patients without MR. Postoperative morbidity and mortality do not differ significantly between the groups. Grade of MR is reduced or unchanged after CABG in patients with grade 2 ischemic MR. The study supports an operative strategy where grade 2 ischemic mitral regurgitation is treated by CABG alone but the result do not exclude that there might be individual patients that would benefit from a valvular or annular procedure in combination with CABG. How these patients should be identified remains unclear.
