About Video

This video clip two-dimensional transthoracic echocardiography parasternal long-axis view shows left ventricular assist device in a patient with cardiomyopathy. Note very poor function of both ventricles. The aortic valve (arrow) does not open and remains in the closed position throughout because all the ventricular flow is routed by the left ventricle (LV) assist device into the proximal ascending aorta (Ao). There is no direct ejection of flow into the AO through the aortic valve; (B) Color Doppler examination shows significant aortic regurgitation (AR). (LA: Left atrium; RV: Right ventricle).
