TCT-520 PROspective, Randomized Comparison of 3-Dimensional Computed Tomography Guidance versus TEE data for Left Atrial Appendage Occlusion (PRO3DLAAO)

Preliminary data comparing 3-dimensional computed tomography (3D-CT) to transesophageal echocardiography (TEE) for left atrial appendage occlusion (LAAO) indicates that 3D-CT provides more accurate measurements and improves case planning. Therefore, we conducted a pilot study comparing 3D-CT to TEE
