2. Transvalvular blood flow as seen by color Doppler flow echocardiography.
Transvalvular blood flow as seen by color Doppler flow echocardiography. Apical 5-chamber view is shown. Right, 23-mm stentless aortic valve; left, 23-mm conventional valve. Blood flow is laminar after SAV implantation, as shown by blue in left ventricular outflow tract. Close to and across stent, blood flow is turbulent after CSB implantation, as shown by yellow, red, and green.
