Percutaneous and surgical approaches have been developed for left atrial appendage occlusion. Residual stump formation with a depth of ≥ 10 mm is a recognized complication after surgical LAAO using AtriClip (Atricure, Mason, Ohio). The standard imaging modality for preprocedural planning and postprocedural follow up during these procedures has been transesophageal echocardiography. The current case describes successful closure of a residual stump, measuring 13 mm in depth, using percutaneous LAAO, with CT imaging utilized for preprocedural planning and postprocedural follow up. Accordingly, this case demonstrates that CT imaging is a viable, convenient, and less invasive alternative for these situations.
