•Cardiac computed tomography (CCT) can be used as a useful complementary tool in preprocedural planning of left atrial appendage closure.•CCT planning includes assessing exclusion criteria, device sizing, sheath selection, anticipating challenging anatomies, and transseptal puncture planning.•Procedural 3D intracardiac echocardiography (3D-ICE) is increasingly being used instead of transesophageal echocardiography. In this setting, preprocedural CCT is useful to compensate for 3D ICE's reduced resolution.
•心脏计算机断层扫描（CCT）可作为左心耳封堵术前规划的有用辅助工具。
•CCT规划包括评估排除标准、确定器械尺寸、选择鞘管、预判复杂解剖结构以及经间隔穿刺规划。
•术中三维心内超声心动图（3D-ICE）越来越多地被用于替代经食管超声心动图。在这种情况下，术前CCT有助于弥补3D-ICE分辨率降低的不足。
