Survival in ischemic mitral regurgitation is related to the degree of mitral regurgitation

In a study of 303 patients with ischemic mitral regurgitation after a myocardial infarction, survival was related to the degree of mitral regurgitation graded by regurgitant volume (RVol) on Doppler echocardiography. In a multivariate analysis, an RVol ≥30 mL/beat was a significant independent predictor of total and cardiac mortality at five years.
