Flow changes in hepatic veins in congestive cardiac insufficiency. A study using pulsed Doppler US.
Ten patients with right heart failure and tricuspid regurgitation were studied with both B Scan and pulsed Doppler ultrasound. Variations in the Doppler waveforms were seen in portal vein recordings which indicated flow characteristics similar to those of hepatic veins due to transmission of retrograde pressure waves through the hepatic capillary bed. It was concluded that the pulsed Doppler will permit non-invasive determination of physiological events that may have great practical importance in the diagnosis and treatment of patients with right heart failure.
