Systolic flow reversal pulmonary vein

WebJul 22, 2024 · Mitral regurgitation (MR) is defined as an abnormal retrograde blood flow from the left ventricle (LV) to the left atrium (LA) during left ventricular contraction. Trivial to mild mitral regurgitation is a common finding and is seen in nearly 50% of healthy people [].Severe MR is relatively uncommon in patients before the fifth decade, but the … WebApr 11, 2024 · Moreover, the pulmonary vein atrial reversal flow velocity is directly proportional to the left atrial systole, that is, the a-wave. Thus, an increase in the pulmonary atrial reverse velocity sixth months after ASD closure means an increase in the left atrial ejection fraction [ 18 ].
