We compared short-term results of a hybrid versus a standard surgical bilateral thoracoscopic approach employing radiofrequency (RF) sources in the surgical treatment of lone atrial fibrillation (LAF).Between January 2008 and July 2010 sixty-three consecutive patients with LAF underwent minimally invasive surgery. Thirty-five (55.5%) underwent surgery with the hybrid approach whereas 28 (45.5%) underwent bilateral thoracoscopic standard procedure (no-hybrid group). All patients underwent continuous 7-day Holter Monitoring (HM) at 3 months, 6 months and 1 year.At 1 year, 91.4% and 82.1% (time-related prevalence 5.2% vs.6.0% [p=0.56]) of the patients were free of AF and AAD. The hybrid group yielded better results in long standing persistent AF (8.2% [time related prevalence 81.8% vs. 44.4%, p=0.001] vs.14.9%, p=0.04). One-year success rates were 87.5% vs. 100% (p=0.04) in persistent [time related prevalence 3.8% vs. 0%, p
