Hybrid Ablation of Persistent and Long-standing Persistent Stand-alone Atrial Fibrillation

This study evaluates in detail efficacy and safety (including neurological safety) of hybrid ablation of stand-alone, persistent and long-standing persistent atrial fibrillation (AF). An implantable ECG monitor will be implanted to all patients for rhythm monitoring. Neurological safety will be assessed by cerebral magnetic resonance, neuropsychological examination and periprocedural transcranial Doppler measurement.
