Introduction: Long-term results of catheter ablation (CA) for persistent and long-standing persistent atrial fibrillation (AF) are disappointing. The hybrid approach is currently one of options for overcoming the limitations of CA. Aim: To evaluate the safety and medium-term efficacy of the hybrid approach in patients with persistent and long-standing persistent AF. Methods: All patients underwent epicardial thoracoscopic radiofrequency (RF) pulmonary vein (PV) isolation using the AtriCure clamp followed by left atrial (LA) linear lesions (using a linear pen), Marshall ligament disruption, and LA appendage exclusion using an Atriclip. All patients underwent an electrophysiological study (EPS) and RF CA 2-3 months after the initial surgery to eliminate recurrent conductions from/to the PVs or across the linear lesions, and to eliminate all spontaneous and inducible atrial arrhythmias. 7-Day ECG Holter monitoring was performed every 3 months during the first year and every 6 months afterwards to evaluate possible recurrent arrhythmias. Results: Seventy patients (49 male, median 63.5 years) took part in the study. EPS was performed 87 days (median) after the thoracoscopic surgery. Seventy-six percent of patients were in normal sinus rhythm (SR) at the start of the EPS, 7% had typical atrial flutter, 11% had atrial tachycardia, and 6% were in AF. After completion of the hybrid approach, all PVs were isolated, while a complete conduction block across the linear lines was achieved in 88.6% of patients. Twelve months after the procedure, 77.1% of patients had a stable SR without any anti-arrhythmic medication or re-ablation. If we included those on anti-arrhythmic drugs and re-ablation procedures, SR was achieved in 96.5% of patients during follow-up (936 +/- 432 days). Conclusion: The sequential hybrid approach is probably the most effective and relatively safe invasive treatment for persistent and long-term persistent AF with very low medium- to long-term recurrences. Introduction of the hybrid approach to clinical practice requires extensive cooperation between cardiologic and cardiothoracic teams. (C) 2017 The Czech Society of Cardiology.
