Prevalence and Phenotypic Characterization of Patients with Bicuspid Aortic Valve and Large Aortic Annular Diameter

Bicuspid aortic valve (BAV) is a heterogenous entity with different anatomic subtypes and various clinical presentations.1,2 Besides a larger sinus of Valsalva (SoV) and ascending aorta, a large aortic annulus (AA) is a classic anatomical feature reported in BAV. However, the exact prevalence of large AAs in patients with BAV is unclear, and phenotypic characterization of patients with BAV and large AAs has not been reported.
