Abstract：Objective To investigare the efficacy and safety of left atrial appendage closure guided by ransesophageal echocardiography(TEE).Methods An total of 80 patients with atrial fibrillation who underwent one-stop radiofrequency ablation and left atrial appendage closure surgery at Xuzhou Central Hospital from October 2020 to December 2022 were inrolled.All the patients underwent left atrial appendage occlusion surgery under TEE.Preoperative TEE evaluation was performed to observe relevant parameters of the patient's examination items,and the safety during the testing process was recorded.Results Out of 80 surgical patients,48(60.00％)underwent Wahchman occluder and 32(40.00％)underwent LAmberTM occluder.Two types of occluders were used for the surgery;the left atrial appendage entrance diameter was 45°,90°,and 135°;the left atrial appendage length diameter was 45°,90°,and 135°;and the occlusion distance was relatively close to that measured by digital silhouette angiography(P＜0.05).Conclusion Transesophageal echocardiography has high application value in the left atrial appendage occlusion surgery for patients with atrial fibrillation.It can accurately measure the left atrial appendage entrance diameter and left atrial appendage length diameter with relatively few clinical complications.It is worth promoting and applying clinically.
