To determine the characteristic change in the Doppler hepatic venous flow velocity pattern in patients with pulmonary hypertension (PH), 21 patients with PH in sinus rhythm were examined with pulsed Doppler echocardiography. The control group included 13 subjects with chest pain syndrome and normal pulmonary arterial pressure. The hepatic vein Doppler signal was biphasic with one peak during ventricular systole (S wave) and the other in diastole (D wave). A reversed signal was recorded after contraction (A wave). The peak velocity of the A wave (Va), S wave (Vs), and D wave (Vd), the time velocity integral of these waves (Vla, Vls, and Vld), the acceleration time (t-AC), and the slope of acceleration (s-AC) in the S wave were measured. Compared with controls the PH group had a higher value of Va (26.88±10.30 vs 13.41±3.69 cm/sec; p<0.01), Vla (2.55±1.18 vs 1.20±0.34cm; p<0.01). Vla/(Vls+Vld) (0.34±0.22 vs 0.14±0.06; p<0.01), and s-AC (372±156 vs 203±103 cm/sec^2. p<0.01). They also had a shorter t-AC (101±32 vs 136±27 msec; p<0.01). There was a weak correlation between the reversed atrial flow and the right heart pressures (r=0.43 to 0.66). Thus, the hepatic venous flow velocity pat-tern by Doppler echocardiography is clinically useful in evaluating pulmonary hypertension.
