Abstract:
Objective:To summarize the safety and efficacy of thoracoscopic minimally invasive " one-stop" ablation for the treatment of atrial fibrillation(AF).Methods:A retrospective study was conducted on all patients with isolated atrial fibrillation who underwent thoracoscopic radiofrequency ablation combined with left atrial appendage clipping(LAAC) at West China Hospital of Sichuan University from September 2019 to October 2023. Preoperative baseline data, perioperative complications, and 3-month, 6-month, and 12-month postoperative follow-up data were collected and analyzed.Results:A total of 87 patients were included, with a mean age of(60.5±9.0) years old. Among them, 47 were males and 40 were females. Of these patients, 12 had paroxysmal AF, and 75 had persistent AF. Fourteen patients had a prior history of catheter-based radiofrequency ablation, and 11 had a history of transient ischemic attack(TIA) or stroke. All procedures were successfully completed without conversion to open thoracotomy, perioperative mortality, or perioperative stroke events. During the follow-up period, one patient died, no strokes or left atrial appendage reconnection events were observed. The sinus rhythm maintenance rates at 3、6 and 12 months postoperatively were 89.6%(78/87)、82.8%(72/87) and 75.9%(66/87), respectively. Multivariate logistic regression analysis identified a preoperative left atrial anteroposterior diameter>40 mm as an independent risk factor for postoperative AF recurrence. Conclusion:Thoracoscopic minimally invasive ablation combined with left atrial appendage clipping as a " one-stop" procedure is a safe and effective method for the treatment of isolated atrial fibrillation, achieving satisfactory surgical ablation success rates while effectively preventing stroke.
