Murine Left Atrium and Left Atrial Appendage Structure and Function: Echocardiographic and Morphologic Evaluation
Fig 5
Mitral valve and pulmonary vein flow velocities: color and pulsed Doppler.
A) Color Doppler flow velocity, standard 4-chamber view, diastolic frame. B) Pulsed Doppler MVf velocity profile. C) Pulsed Doppler PVf velocity profile. Green line on the ECG shows a 50 ms duration. A: MV wave; D: PV diastolic wave; LA: left atrium; LV: left ventricle; LVout left ventricle outflow; MVf: mitral valve flow; PVd right superior pulmonary vein diameter; PVf: right superior pulmonary venous flow; RA: right atrium; RV: right ventricle; S1: PVf early systolic wave; S2: PVf late systolic wave.
