AbstractHepatic vein flow can be reliably measured because Doppler sampling volumes are easily oriented parallel with the course of the hepatic vein. In this study, the relationship between the Doppler signal in the hepatic vein and the external jugular vein pulse was evaluated, and the contribution of the Doppler echocardiography to the quantitative diagnosis of tricuspid regurgitation was also assessed. The subjects consisted of five healthy persons, four patients with lone atrial fibrillation, 27 patients who underwent cardiac surgery, and 34 patients with tricuspid regurgitation. The severity of the regurgitation was judged by right ventriculography and inferior caval angiography. The pattern of the Doppler hepatic vein flow mimicked that of the jugular phlebogram in each patient. The normal hepatic vein flow consisted of two forward flows toward the heart; one in systole; the other, in diastole, and one retrograde flow toward the liver during atrial contraction. In patients with lone atrial fibrillation, a systolic backward flow toward the liver or a decrease in the systolic forward flow was observed, though there was no tricuspid regurgitation. In patients who had cardiac surgery, a systolic backward flow toward the liver or a decrease in the systolic forward flow was usual. However, a prominent systolic backward flow toward the liver was observed in patients with severe tricuspid regurgitation, and a decreased systolic forward flow toward the heart was observed in patients with moderate tricuspid regurgitation in sinus rhythm. We concluded that Doppler measurement of hepatic vein flow does not contribute to the diagnosis of tricuspid regurgitation in the presence of atrial fibrillation or in postoperative conditions, but that it is useful in identifying severe tricuspid regurgitation.
