Characteristics of Bicuspid Aortic Valve Disease and Stenosis: The National Echo Database of Australia.

ABSTRACT: Background Bicuspid aortic valve (BAV) is the most common congenital heart disease in adults but is clinically heterogeneous. We aimed to describe the echocardiographic characteristics of BAV and compare patients with BAV with moderate-to-severe aortic stenosis (AS) with those with tricuspid aortic valve (TAV) stenosis. Methods and Results Using the National Echo Database of Australia, patients in whom BAV was identified were studied. Those with moderate-to-severe AS (mean gradient >20 mm Hg [BAV-AS]) were compared with those with TAV and moderate-to-severe AS (TAV-AS). Of 264 159 adults whose aortic valve morphology was specified, 4783 (1.8%) had confirmed BAV (aged 49.6±17.4 years, 69% men). Of these, 42% had no AS, and 46% had no aortic regurgitation. Moderate-to-severe AS was detected
