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.
