Purpose: The purpose of this study was to analyze the efficacy and complication rates of a one-stage left unilateral thoracoscopic hybrid procedure in a series of patients with persistent and long-standing persistent atrial fibrillation (AF) in a 2-year follow-up. Methods: Fifty-one consecutive patients (34 males, 65.7 ± 8 years) having undergone hybrid isolation of pulmonary veins (PVs) and posterior wall of left atrium (LA) by means of left unilateral hybrid thoracoscopic ablation for symptomatic persistent (n = 22, 43%) and long-standing persistent atrial fibrillation (AF) (n = 29, 57%) were analyzed. Results: At a mean follow-up of 24.9 ± 11.8 months (median 24), the success rate without antiarrhythmic therapy was achieved in 68.6% of patients. Procedure-related major complications were observed in 2 patients (4%) including diaphragmatic perforation and late pericardial tamponade requiring mini left-sided thoracotomy and pericardial drainage, respectively. The success rate did not significantly differ between persistent and long-standing persistent AF (respectively, 68.2 and 69%; P = 0.89). Patients with AF relapse during the blanking period were 3.8 times more likely to have AF recurrence after 3 months from the ablation procedure. Conclusion: The hybrid one-stage left unilateral thoracoscopic procedure exhibits encouraging results in the setting of both persistent and long-standing persistent AF after a 2-year follow-up, at a low rate of adverse events.
