NEW ORLEANS — Along with symptomatic status, elevated indexed left ventricular end-systolic dimension predicted mortality in patients with moderate to severe or severe aortic regurgitation but no CAD, researchers reported at the American College of Cardiology Scientific Session.

The researchers analyzed 748 patients (mean age, 58 years; 82% men) with moderate to severe or severe aortic regurgitation but no history of MI, CAD or heart surgery to assess whether they benefited from surgery and what characteristics might predict outcomes. The findings were simultaneously published in the Journal of the American College of Cardiology.
