- Abstract: Objective To investigate the value of transesophageal echocardiography (TEE) analysis on left atrial appendage in guiding left atrial appendage occlusion. Methods A total of 110 patients scheduled for left atrial appendage occlusion were enrolled in the study. All patients were given TEE examination before operation, and the parameters such as the maximum diameter of left atrial appendage opening and the distance from pectinate muscle to the opening were analyzed. Results The left atrial appendage was successfully occluded in 110 patients, and there were 19 cases of residual shunt and 91 cases of no residual shunt. The operation lasted for 17-80 min, with an average of (45.49±13.30) min. The radiation dose was 560-2 100 mGy, with an average of (980.50±112.40) mGy, and the exposure duration was 520-1 950 s, with an average of (890.50±120.40) s. The maximum diameter of left atrial appendage opening measured by TEE was (23.12±2.24) mm, less than the size of ACP which was 18-33 mm, with an average of (25.50±2.50) mm (P<0.05), and the maximum diameter of left atrial appendage opening measured by TEE was positively correlated with the size of ACP (r=0.426, P<0.05). No statistically significant difference was found in the maximum diameter of left atrial appendage opening, the depth of left atrial appendage and their ratio between patients whose operation duration <45 min and ≥45 min (P>0.05). The distance from pectinate muscle to the opening was (16.60±3.22) mm in patients whose operation duration <45 min, which was significantly longer than that in patients whose operation duration ≥45 min (P<0.05). The distance from pectinate muscle to the opening was negatively correlated with operation duration (r=-0.524, P<0.05). Conclusion TEE analysis on the internal morphological structure of left atrial appendage has certain guiding value for left atrial appendage occlusion, worthy of clinical application.
