Abstract Objective: To evaluate the value of trans-esophageal echocardiography(TEE) and CT in the pre-operation of left atrial appendage occlusion. Methods: One hundred and eighteen pre-operative TEE and CT results of left atrial fibrillation fitting left atrial appendage occlusion were selected to analysis retrospectively from May 2013 to April 2016. Results: One hundred and eighteen patients were enrolled, including 43 males and 75 females, mean age (55.6±5.8) years. TEE was shown 10 patients with thrombus in the left atrial appendage, CT was shown 5 patients filling defect in left atrial appendage. According to the shape of left atrial appendage, 4 types were individed: chicken wing type(56 cases, 51.9%), cauliflower type(22 cases, 20.3%), vane type(21 cases, 19.4%), cactus type(9 cases, 8.4%). Left atrial appendage orifice was classified into 3 types: oval type(95 cases, 88.0%), round type(8 cases, 7.4%), water-drop type(5 cases, 4.6%). Conclusions: TEE is an effective method to screen out left atrial appendage thrombosis patients in pre-operation of left atrial appendage occlusion which is better than CT, but CT examination provides more anatomical informations in pre-operation of left atrial appendage occlusion, so the combination of two examinations can provide more accurate support for the success of the operation.
