LVOT diameter/radius measurements for the calculation of stroke volume and cardiac output with pulsed-wave Doppler (PWD) are done at the attachment of the aortic cusps (see Figure 9-8). Note poor aortic cusps separation due to decreased LV systolic function (LVEF%). LVEF, left ventricular ejection fraction; LV, left ventricle; LVOT, left ventricular outflow tract.
