From: Intraventricular Vortex Interaction between Transmitral Flow and Paravalvular Leak

Color Doppler imaging, continuous Doppler echocardiography. (A–C) Color Doppler imaging and continuous wave (CW) Doppler echocardiography. Obvious regurgitant signal was observed in (B) and (C) and the interaction between the PVL jet and the transmitral flow was observed in (C). Red and blue arrows indicate systole and diastole, respectively. (D) and (E) Width of the PVL jet and outflow tract in anterior and posterior PVL case.
