©2013 UpToDate ® Print Email Pulmonary vein flow in severe mitral regurgitation The continuous wave Doppler, obtained from the pulmonary vein (PV), shows systolic flow reversal or retrograde systolic flow, which is the hallmark of severe mitral regurgitation (MR) and is the flow analogue of the v-wave seen on the pulmonary artery catheter wedge pressure tracing.
©2013 UpToDate ® Print Email Pulmonary vein flow in severe mitral regurgitation The continuous wave Doppler, obtained from the pulmonary vein (PV), shows systolic flow reversal or retrograde systolic flow, which is the hallmark of severe mitral regurgitation (MR) and is the flow analogue of the v-wave seen on the pulmonary artery catheter wedge pressure tracing. Continuous wave Doppler from the pulmonary vein in mitral regurgitation The systolic flow, which is normally dominant, is depressed and the retrograde flow at the time of atrial contraction, which is normally less than the transmitral A wave, is exaggerated.
