Objective To investigate the value of 3D-TEE, 2D-TEE, CTA and X-ray contrast in assessing left atrial appendage (LAA) shape, size and guidance for the choice of occlusion. Methods Forty-three cases of left atrial fibrillation who were referred for LAA closure were performed TEE to measure the opening maximum diameter, and maximum depth of 2D-TEE at 0°, 45°, 90° and 135°. When LAA showed most clearly, the opening maximum and minimum diameter of LAA were measured by using 3D-ROOM mode, and the results were compared with those measured by CTA and X-ray contrast. Results There was no significant difference for opening maximum diameter of LAA measured by 3D-TEE, 2D-TEE and X-ray contrast (allP>0.05), but that of CTA statistically larger than 3D-TEE, 2D-TEE, X-ray contrast (allP<0.01). There were significant difference between 2D-TEE at 90°, 135° and CTA, 2D-TEE at 135° and X-ray contrast in assessing maximum depth of LAA (allP<0.05). Opening maximum diameter of LAA measured by 3D-TEE was significantly correlated with each angle of 2D-TEE, CTA, and X-ray contrast (r=0.70—0.77, 0.57, 0.58, allP<0.01), and the opening maximum diameter measured by 2D-TEE also correlated with CTA and X-ray contrast (r=0.57—0.71, 0.45—0.51, allP<0.01). Also the opening maximum diameter measured by 3D-TEE, 2D-TEE, CTA and x-ray contrast were correlated with occluder size (r=0.93, 0.70—0.77, 0.57, 0.47, allP<0.01). Conclusion Compared with 2D-TEE, CTA and X-ray contrast, 3D-TEE is more instructive for occluder selection.
