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