[Changes in the flow patterns of the hepatic veins obtained by pulsed Doppler during the postoperative follow-up of a patient with acute aortic insufficiency].

: Blood flow pattern recording of hepatic veins using pulsed Doppler technique is a valid method for the assessment of hemodynamic changes in right atrium. We describe a patient with severe aortic regurgitation secondary to acute infective endocarditis who underwent surgical repair. Before surgery and during the postoperative period, several evolutive studies (including conventional echo and hepatic veins pulsed Doppler recordings) were performed. The different central blood flow patterns were correlated with changing hemodynamic conditions during follow-up of the patient. These central flow velocities reflect changes in right atrial pressure contours, and are easily obtained non-invasively with pulsed wave Doppler ultrasound of the hepatic veins. They could be an useful method for assessing right heart filling dynamics, reporting characteristic patterns in other cardiac disease states.
