<scp>CUTE</scp>‐<scp>CV</scp>: A Prospective Study of Enhanced Left Atrial Appendage Visualization with Microbubble Contrast Agent Use during Transesophageal Echocardiography Guided Cardioversion

Abstract

LAA dimensions and contractility indices were higher, artifacts were significantly differentiated, previously unsuspected LAA filling defects were identified, and the level of confidence in excluding thrombus was enhanced in the contrast images when compared to the noncontrast images. After 4 months follow-up, 1 stroke-associated death occurred in a patient who had LAA thrombus recognized only by contrast. Left atrial appendage visualization is enhanced with microbubble contrast agent use during transesophageal echocardiography guided cardioversion and is useful in identification of intracardiac thrombus.
