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 ... eap services sydneyWebKey: D = Diastolic wave, AR = Atrial systolic reversal and S = Systolic wave.
