Spectral Doppler of the hepatic veins in tricuspid valve disease.

Spectral Doppler recording of the hepatic veins (HV) provides a semiquantitative assessment of tricuspid regurgitation (TR) severity. It complements findings on two-dimensional echocardiography and color Doppler imaging and helps to discriminate between hemodynamically significant and nonsignificant degree of regurgitation. In this manuscript, we discuss the usefulness of the HV Doppler for the diagnosis of tricuspid valve (TV) disease and provide examples of the various spectral Doppler patterns that assist in the quantification of TR.

Elevated right ventricular end-diastolic pressure by Doppler echocardiography-a case report.

Careful analysis of the right-sided Doppler signals provides important data regarding right heart hemodynamics. Here, we illustrate the value of the combined analysis of flow across the hepatic vein, tricuspid valve, and pulmonary valve for the diagnosis of elevated right ventricular end-diastolic pressure.
