Pre and Post Procedure Imaging of the Watchman® Device with Cardiac Computed Tomography Angiography.

ABSTRACT

PURPOSE OF REVIEW Left atrial appendage occlusion with the Watchman® device requires pre and post procedure imaging. Currently, transesophageal echocardiography is the recommended modality, though cardiac computed tomography angiography may be an acceptable alternative. RECENT FINDINGS: Cardiac computed tomography angiography can be used to safely and accurately predict Watchman® device sizing. It can also be used to detect post procedure complications similar to, or better than, transesophageal echocardiography. Cardiac computed tomography angiography is a viable alternative imaging modality for pre and post procedure evaluation for the Watchman device.
