When performing a Doppler examination of the inferior vena cava and/or hepatic veins for evidence of tricuspid regurgitation, onw would expect to find:
A.) Flow toward the transducer in diastole.
B.) Flow toward the transducer in systole.
C.) Flow away from the transducer in systole.
D.) Flow away from the transducer in diastole.
B.) and d.) scanning for the inferior vena cava and the hepatic vein is completed in the subcostal position. The presence of flow toward the transducer in systole when flow in the inferior vena cava and/or hepatic vein is being insonated is evidence for tricuspid regurgitation. Normal flow is always away from the transducer in diastole, with or without tricuspid regurgitation.
