Diastolic dominant pulmonary vein flow
WebHepatic venous flow patterns included double-peaked flow signals toward the right atrium, and the relationship between systolic (S) and diastolic flow velocities (D) was expressed as the velocity ratio [S/(S+D)]. A reversed flow during atrial systole was expressed as an "A wave" and that between the S and D waves, as an "O wave". WebAlthough the assessment of pulmonary venous flow (Fig. 2) can help to identify raised filling pressure (and hence discriminate normal from pseudonormal), the combination of patterns is complicated ...

WebDec 1, 2003 · Normal pulmonary venous flow is characterized by a velocity during ventricular systole that is higher than during ventricular diastole. With increasing severity of MR, there is a diminution of the systolic velocity. In many patients with severe MR, the flow in the pulmonary veins becomes reversed in systole ( Fig. 4). Since the mitral ...
