经导管左心耳封堵术越来越多地用于房颤患者的卒中预防。该技术已在随机试验和多项观察性研究中证明有效且安全。由于左心耳的解剖结构复杂，该手术具有挑战性;准确的心脏成像对于手术指导至关重要。经食管超声心动图是金标准，但心脏计算机断层扫描（CT）近年来已获得越来越多的关注。心脏CT提供了高分辨率成像，允许进行术前解剖评价和器械尺寸测量，但也可用于排除左心耳血栓，并对残留器械周围泄漏进行随访评估。
Transcatheter left atrial appendage occlusion is increasingly used for stroke prevention in atrial fibrillation. The technique has proven effective and safe in randomized trials and multiple observational studies. The procedure is challenging due to the complex anatomy of the left atrial appendage; accurate cardiac imaging is essential for procedural guidance. Transesophageal echocardiography is the gold standard, but cardiac computed tomography (CT) has gained increasing interest within recent years. Cardiac CT offers high-resolution imaging allowing for preprocedural anatomic evaluation and device sizing, but may also be useful for exclusion of left atrial appendage thrombus, and follow-up assessment of residual peri-device leaks.
