Persistent AF is still a refractory disease, and single catheter ablation only has a success rate around 30-50%. Hybrid strategy consisting of thoracoscopic epicardial ablation and transvenous endocardial ablation seems to be an attractive procedure to improve the treatment of persistent AF. However, only a few centers reported their preliminary results, and the conclusions are controversial. The investigator previously reported a minimally invasive surgical ablation from left thoracoscope only and achieved good results. Recently, the investigator successfully explored a hybrid procedure combing this unique surgical technique and transvenous catheter ablation. Here, the investigator present a study to evaluate the efficacy and safety of this novel hybrid procedure. The hypothesis is that a hybrid approach is more efficient than surgical ablation alone in the treatment of persistent AF.\n\nThis study is a non-randomized controlled study within a single institution. Isolated persistent AF patients admitted to the cardiovascular surgery department of Shanghai Xinhua Hospital will be screened for enrollment of this study. The study will recruit 180 patients in total. Based on their own willingness, the patients will be divided into hybrid group and minimally invasive (MIS) group. The MIS group patients only have surgical ablation surgery from left thoracoscope as the investigator reported before, while the hybrid group patients will have additional transvenous catheter ablation after the surgical ablation is done during the same operation. The ratio of hybrid to MIS group is expected to be 1:1, so that each group contains 90 patients. The perioperative data is collected, and the patients will be followed for 6 months. The primary outcome is the rate of sinus rhythm at 6 months post operation. The secondary outcomes include off antiarrhythmic drug rate, perioperative complications, major cardiovascular events, stroke, left ventricular systolic function, medical expense, serum brain natriuretic peptide level and quality of life. The aim is to evaluate the efficacy and safety of this novel hybrid procedure, therefore to provide more evidence of the hybrid strategy in the treatment of persistent AF.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria\n\n1.
