Hepatic vein velocities in children with right ventricular hypertension

The important finding of this study was that Doppler assessment of hepatic venous velocities demonstrates reduced or negative velocities in the first half of diastole in children with right ventricular hypertension. The only other hepatic venous waveform change occurred during end-diastole and atrial contraction. At that time amplitude of reversed blood velocity in the hepatic vein increased directly with increased right ventricular pressure, but the magnitude of increase was not clinically significant.
