mportance of Moderate Ischemic Mitral egurgitation

d a v p s a o Background. The importance of moderate ischemic itral regurgitation in patients presenting for coronary rtery bypass grafting (CABG) is controversial. Thereore, we tracked the course of unrepaired moderate schemic mitral regurgitation after CABG surgery alone, dentified factors associated with worsening postoperaive ischemic mitral regurgitation, and assessed the imact of unrepaired moderate ischemic mitral regurgitaion on survival. Methods. From 1980 to 2000, 467 patients with moderate schemic mitral regurgitation underwent CABG alone. he course of unrepaired mitral regurgitation was estiated by a longitudinal analysis of 267 follow-up echoardiograms from 156 patients. The survival impact of oderate ischemic mitral regurgitation was determined mong propensity-matched patients with and without schemic mitral regurgitation. Results. Mitral regurgitation was dynamic early postperatively. Immediately postoperatively, it was absent
