The pathologic etiology of MR was determined on preoperative echocardiogram, and patients were stratified into no\/mild MR (Group I; n =338) versus moderate MR (Group II; n =70). Follow-up was 95.1% complete. Functional outcome was evaluated using the Short Form-12 questionnaire. On univariate analysis, Groups I and II differed in incidence of previous myocardial infarction (13.9% versus 28.6%;\n            <jats:italic>P<\/jats:italic>\n            =0.004), hyperlipidemia (18.7% versus 33.3%;\n            <jats:italic>P<\/jats:italic>\n            =0.009), and congestive heart failure (50.0% versus 70.0%;\n            <jats:italic>P<\/jats:italic>\n            =0.002). On multivariate analysis, moderate MR was an independent risk factor impacting long-term survival (\n            <jats:italic>P<\/jats:italic>\n            =0.04). Actuarial survival at 1, 5, and 10 years for Group I was 93.8%, 73.3%, and 40.1% versus 92.3%, 58.2%, and 14.6% for Group II (\n            <jats:italic>P<\/jats:italic>\n            =0.04). Available postoperative echocardiograms for Group II (n =37) demonstrated improvement in MR in 81.8% of functional MR patients. However, MR persisted or worsened in 65.4% of patients with intrinsic mitral valve disease (myxomatous, calcific, or ischemic MR). Functional outcomes showed 77% of Group I versus 78.6% of Group II rated their health as good to excellent post-AVR.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>Conclusions\u2014<\/jats:italic>\n            <\/jats:bold>\n            Moderate MR is an independent risk factor impacting long-term survival in elderly patients undergoing AVR.
