Figure 48i

Aortic regurgitation, pulsed wave. Doppler recording.
Top: Parasternal long-axis image, showing orientation of the Doppler cursor and location of the smple volume (arrow) in the center of the outflow tract, on the left ventricular side of the aortic leaflets. LV, left ventricle; Ao, aorta; LA, left atrium.
Bottom: Spectral Doppler recording. Diastolic regurgitant flow is disturbed, and thus multidirectional, causing a broad spectrum of Doppler shifts (open arrows) that last through diastole.
