Figure 5. Echo-Doppler studies in parasternal long-axis (A, B) and subcostal (C, D) projections illustrating supravalvar aortic stenosis. Note that the stenosis is above the aortic valve as shown with arrows. Color flow imaging shows turbulence in the Doppler flow signal as pointed out with arrows (B, D). An increased Doppler flow velocity was recorded superior to the aortic valve but is not illustrated in the above echo frames. The left atrium (LA) and left ventricle (LV) are labeled.
