Figure 2

A classification scheme for bicuspid aortic valve (BAV) morphology based on the symmetry and position of the leaflets. Asymmetric BAVs (ABAVs), with two cusp angles of 240°–120°, includes ABAV-1, ABAV-2, and ABAV-3 morphologies. Symmetric BAVs, with two cusp angles of 180°–180°, includes SBAV-1 and SBAV-2 morphologies. The spatial positions of the leaflets are defined based on the aortic quadrant that the leaflets face. LA left-anterior quadrant of the ascending aorta, LP left-posterior quadrant of the ascending aorta, RA right-anterior quadrant of the ascending aorta, RP right-posterior quadrant of the ascending aorta, LL larger leaflet, SL smaller leaflet.
