Figure 1 Examples of selected two-dimensional color Doppler images for measurements of forward flow volume in the left ventricular outflow tract (LVOT) (top) and right ventricular outflow tract (RVOT) (bottom). Note that the sampling volume is at a depth of 3.5 cm for the RVOT, but it is almost 8 cm from the apex in the LVOT view. Ao = aorta; LV = left ventricle; PA = pulmonary artery; RV = right ventricle.
