Eligibility | Inclusion Criteria: 1. The subject is of legal age to participate in the study per the laws of their respective geography. 2. The subject has documented non-valvular persistent AF. For this protocol, the definition of persistent AF is sustained arrhythmia lasting at least 7-days but less than 36 months. 3. The subject is able to tolerate OAC post ablation. 4. Subject is able to undergo TEE. 5. The subject or legal representative is able to understand and willing to provide written informed consent to participate in the trial 6. The subject is willing and capable of attending all follow-up visits at the investigational site as medically appropriate. Exclusion Criteria: 1. The subject is unable or unwilling to return for required follow-up visits and examinations. 2. The subject had or is planning to have any invasive cardiac procedure within 30 days prior to randomization (e.g., cardioversion, ablation). 3. Previous AF ablation (surgical or percutaneous). 4. Prior MAZE procedure. 4. The subject is planning to have any cardiac or non-cardiac invasive or surgical procedure that would necessitate stopping or modifying the protocol required medication regimen within 90 days after the WATCHMAN Closure Device implant (e.g., cardioversion, ablation, cataract surgery). 5. The subject had a prior BARC type 3 or 4 bleeding event within the 14 days prior to randomization. Lack of resolution of related clinical sequelae, or planned and pending interventions to resolve bleeding/bleeding source, are a further exclusion regardless of timing of the bleeding event. 6. The subject had a prior stroke (of any cause) or TIA within the 30 days prior to randomization. 7. The subject had a prior BARC type 3 or 4 bleeding event within the 14 days prior to randomization. Lack of resolution of related clinical sequelae, or planned and pending interventions to resolve bleeding/bleeding source, or a further exclusion regardless of timing of the bleeding event. 8. The subject has a history of atrial septal repair or has an ASD/PFO device. 9. The subject has an implanted mechanical valve prosthesis in any position. 10. The subject suffers from New York Heart Association Class IV Congestive Heart Failure. 11. Subject has LVEF <30% 12. Subject has hypertrophic cardiomyopathy. 13. The subject has had a myocardial infarction (MI) documented in the clinical record as either a non-ST elevation MI (NSTEMI) or as an ST elevation MI (STEMI), with or without intervention, within 90 days prior to randomization. 14. The subject is of childbearing potential and is, or plans to become pregnant during the time of the study (method of assessment upon study physician's discretion). 15. The subject is currently enrolled in another investigational study or registry that would directly interfere with the current study, except when the subject is participating in a mandatory governmental registry, or a purely observational registry with no associated treatments. Each instance should be brought to the attention of the sponsor to determine eligibility. 16. The subject has a documented life expectancy of less than two years. 17. The subject has a known or suspected hypercoagulable state |
