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". 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 ...
