This Research Letter presents AtriAN’s second clinical study in which 12 cardiac surgery patients, with concomitant paroxysmal AF, underwent the epicardial GP ablation treatment. No post- operative AF occurred. Patients were monitored by 24-hour Holter at 1, 3, 6 and 12 months post- procedurally. One patient recorded a short asymptomatic event at 3 months but otherwise no AF was detected in any of the patients. Two heart rate variability parameters (rMSSD and HF power) showed durable decreases, thereby providing a further indication of denervation.
