Summary: | Transcatheter left atrial appendage occlusion is an increasingly used alternative to oral anticoagulation in selected patients with atrial fibrillation. Pre-procedural imaging is a prerequisite to a successful intervention, with transesophageal echocardiography as the current gold standard. However, cardiac computed tomography offers improved imaging with high-quality multiplanar and 3-dimensional reconstructed images. Nevertheless, the lack of a standardized imaging protocol has slowed the adoption of cardiac computed tomography into clinical practice. On the basis of current research and expert consensus, this paper provides a protocol for the preparation, acquisition, and interpretation of cardiac computed tomographic imaging in pre-procedural planning of left atrial appendage occlusion.

•Cardiac CT is increasingly used to plan transcatheter LAAO.•High-quality multiplanar and 3D imaging allow accurate device sizing and efficient LAAO.•A standardized protocol for cardiac CT is paramount for a high-quality result.•Pre-procedural cardiac CT may improve the accuracy, efficacy, and safety of LAAO. |
