LV outflow tract diameter measurement

Figure 1. When the left ventricular outflow tract (lvot) diameter is difficult to visualize in the parasternal long axis view, adding color Doppler may help in delineating the septal endocardium just proximal to the aortic valve annulus (Figure 1, green arrow), where lvot diameter has to be measured. In Figure 1, blue systolic velocities in the lvot help the positioning of the caliper (Figure 2) (blue cross) on the septal endocardium.
