    Objective: The aim of this study was to assess the incremental benefit of denervation of vagal responses for the prevention of recurrence of atrial fibrillation (AF) in patients undergoing a mini-maze procedure. Patients and methods: Between September 2007 and May 2009, 209 patients (aged 53 ± 10 years, 63 male) undergoing cardiac surgery underwent concomitant radiofrequency ablation for persistent AF. Intraoperative highfrequency stimulation showed a positive vagal response in 103 patients and a negative vagal response in 106 patients. The average history of AF was 36 ± 43 months. Preoperatively, 144 patients (68.9%) were in New York Heart Association functional class III or IV. Results: There were no in-hospital deaths, and no significant differences in mortality or complications between the two groups during the postoperative or follow-up periods. Immediately after su..
