Figure 10.41 Pulsed-wave Doppler image of the aortic valve is made from a left parasternal long axis view. The normal flow at the
aortic valve is laminar and below the baseline. The sharp line seen above the baseline represents valve closure (arroe).
Figure 10.42 Pulsed-wave Doppler image in the left ventricular outflow tract shows a slight decrease in flow compared to the level
of the aortic valve. Notice the position of the pulsed Doppler cursor in the near field within the left ventricular outflow tract.
