Two-dimensional right parasternal short-axis echocardiogram at the level of the aortic valve (A) and color flow mapping of pulmonary blood flow (B) of the same dog as in Figure 1. Notice the echogenic membranous stenosis (arrowheads) distal to the pulmonic valve (arrows). Color flow Doppler ultrasonography shows turbulent blood flow during systole, as indicated by a mosaic-like color display, at the level of the stenotic lesion. Blood flow is laminar at the level of the pulmonic valve. Scale markers to the left and right of images indicate distance in centimeters. Ao = Aorta. LA = Left atrium. RVOT = Right ventricular outflow tract.
