Assessment of aortic regurgitant severity from pulsed Doppler recording of abdominal aorta flow.
Top: Subcostal image showing the Doppler sample volumme (arrw) positioned in the abdominal aorta. Systolic flow is oriented toward the transducer. AA, abdminal aorta.
Bottom: Pulsed Doppl velocity curve shows anterograde systolic flow above the baseline and retrograde flow that lasts through out diastole (open arrow). This indicates severe regurgitation.
