WebAccurate interpretation of the spectral Doppler tracing from the hepatic veins is valuable, as it reflects important cardiac and hepatic physiology. Normally, there are four phases: A, S, V, and D; the S and D waves indicate flow in the antegrade direction toward the heart. WebThe hepatic veins (HVs) drain blood from the liver into the inferior vena cava. The normal Doppler waveform obtained from the HVs is tripha-sic (Fig. 7). This phasicity is dependent on varia-tions in central venous pressure during the cardiac cycle. A lack of …
