The use of the Watchman left atrial appendage occlusion device (Boston Scientific Inc.) is becoming increasingly frequent in patients with atrial fibrillation. Cardiac computed tomography (CT) for device sizing pre‐procedure can help facilitate more accurate device selection compared with transesophageal echo (TEE) alone. CT can also help identify minor lobes and trabeculations that may not be apparent on TEE. We report a series of three cases to highlight the utility of a novel application of CT‐TEE fusion imaging to provide procedural guidance during Watchman implant and to assess for peri‐device leak post‐implant.
