Summary

Percutaneous left atrial appendage occlusion (LAAO) is an increasingly used alternative to oral anticoagulation in patients with nonvalvular atrial fibrillation (AF). Transesophageal echocardiography (TEE) and fluoroscopy were used to measure the maximal diameters of LAA. However, the LAA maximal diameters measured on Two dimensional (2D) views could be limited due to the morphology of LAA varies with each individua. Three dimension computed tomography angiography technology (3D-CTA) is based on cardiac computed tomography angiography (CCTA). The 3D-CTA technology provides an innovative measuring method of LAA to guide the selection of device size, and the best fluoroscopy view to implant device. This measuring method and guideline have never been reported and its role in LAAO is uncertain
