Figure 1. Echo-Doppler studies illustrating a thick (A) and bicuspid (B) aortic valve (BAV) with doming of the aortic valve (AV) (C). Color flow imaging demonstrates turbulent flow (TF) at the aortic valve (arrow) (D). The Doppler velocity via the AV is low (< 2 m/s) (E), suggesting trivial aortic stenosis with a bicuspid aortic valve. The left atrium (LA) and left ventricle (LV) are labeled.
