Pulsed Doppler characterization of left atrial appendage flow
J Jue, T Winslow, G Fazio, RF Redberg, E Foster… - Journal of the American …, 1993 - Elsevier
Recent evidence suggests that left atrial (LA) appendage velocities may provide clues to the
thrombogenic potential of this structure. Pulsed Doppler evaluation of LA appendage flow
during transesophageal echocardiography was performed in 109 patients to evaluate the
effects of rhythm, mitral regurgitation, and spontaneous contrast. During sinus rhythm, there
was a forward LA appendage contraction wave of 46±18 cm/sec followed by a retrograde
filling wave of 46±17 cm/sec. In 40% of the patients in sinus rhythm, additional forward and …
