Feasibility Trial of a Staged Epicardial & Endocardial Approach for Treatment of Patients With Persistent or Long Standing Persistent Atrial Fibrillation With Radiofrequency Ablation
The purpose of this study is to assess the safety and technical feasibility of treating subjects with Persistent Atrial Fibrillation or Longstanding Persistent Atrial Fibrillation in a minimally invasive thoracoscopic ablation procedure utilizing the AtriCure Bipolar System, with mapping and additional lesion creation/ gap closure (as needed) provided by currently approved catheter technology, when the epicardial and endocardial phases are performed in a staged manner within 1-10 days apart, during the same hospitalization.
- device : Ablation procedure staged catheter ablation
Phase: Phase 1/Phase 2
Ages Eligible For Study:
- Age > 18 year - Patients with symptomatic persistent or longstanding persistent AF refractory to a minimum of one Class I or III AAD(s). - Patients with failed catheter ablation attempts are eligible if the patients are symptomatic with persistent or longstanding persistent AF. (catheter ablation procedure must be more than 3 months prior to index procedure) - Life expectancy of at least two years - Patient will and able to provide informed consent - Patient is willing and able to attend the scheduled follow-up visits
