Secondary End Point
No complications that seriously affected a patient’s life occurred during the perioperative period. During the operation, there was one case of bleeding of about 100mL in the LAA through the intercostal pathway, and one patient developed a reaction to the anesthesia (nausea and vomiting after surgery) (Table 3). The endotracheal tube was removed within 6 hours after the completion of surgery. Postoperative and half-year follow-up TEE reexamination showed successful closure of the LAA in all patients with no flow or minimal residual flow of 2mm in two patients.
The results of half-year follow-up showed that sinus rhythm without recurrences of AF is 68.8%. Endocardial electrophysiologic examination and radiofrequency ablation were performed in recurrent patients.
