Role of TEE and CT in Determining Suitability of Endovascular LAA Occlusion
(A) Multiplanar 3D TEE images to measure the size of LAA orifice. (B) 3D TEE demonstrates large thrombus (arrows). (C, D) Pre-procedural CT for the LAA dimensions using orthogonal views of the appendage and (E) finally calculating the most effective dimensions of the LAA. CT = computed tomography; TEE = transesophageal echocardiography; other abbreviations as in Figure 1. (A, B) Reprinted with permission Yu et al. (1). (C) Reprinted with permission from Siobhan et al.
