The Preliminary Results of Left Atrial Appendage Occlusion in Patients With Non-valvular Atrial Fibrillation / 中国循环杂志

ABSTRACT

Objective: To explore the feasibility with the safety at peri-operative and early post-operative periods for left atrial appendage occlusion in patients with non-valvular atrial ifbrillation (AF). Methods: A total of 17 non-valvular AF patients with transesophageal echocardiography (TEE) and CAHDS2 evaluation who received left atrial appendage occlusion in our hospital were summarized. The effect and complications during peri-operative and 1 month post-operative periods were analyzed. Results: All 17 patients had successful operation without severe complications. There were 8 patients having small amount residual shunt by TEE examination, 2 having ecchymosis near the puncture point at peri-operative period and 3 having small amount of hydropericardium by peri-cardio ultrasound examination. At the average of 45 days follow-up study, only 3 patients had small amount residual shunt, no left atrium thrombus and hydropericardium were observed. Conclusion: Left atrial appendage occlusion has the high success rate, it is safe during peri-operative and early post-operative periods in non-valvular AF patients.
