Pulmonary Hypertension and Long-term Mortality in Aortic and Mitral Regurgitation

Long-term (15-year) survival of patients with aortic regurgitation is poor and is independent of regurgitation severity. In contrast, long-term survival of patients with mitral regurgitation correlates with regurgitation severity. For both groups, moderate or greater pulmonary artery systolic hypertension identified those at highest risk.
