• 6. Subject is able to understand and willing to provide written informed consent to participate in the clinical investigation
• 7. Subject is able and willing to return for required follow-up visits and protocol required clinical investigation activities
• 8. 18 years of age or older, or the age of legal consent
• 1. Required to take P2Y12 platelet inhibitor beyond 6 months when Amulet 2 LAA Occluder implant procedure would occur
• 2. Is considered at high risk for general anesthesia in the opinion of the Investigator or based on past adverse reaction(s) requiring medical intervention or which resulted in prolongation of hospital stay
• 3. Atrial septal defect or patent foramen ovale repair or occluder
• 4. Implanted with a mechanical valve prosthesis
• 5. Subject anatomy will not accommodate or is contraindicated for transesophageal echocardiography probe use (e.g., presence of esophageal varices, esophageal stricture, or history of esophageal cancer), or subject has experienced adverse events related to transesophageal echocardiography acquisition or has refused transesophageal echocardiography acquisition in the past
• 6. Underwent any cardiac or non-cardiac intervention or surgery within 30 days prior to when Amulet 2 device implant procedure would occur (any intervention or surgery that utilized anesthesia, anesthetic, or sedation)
• 7. Underwent catheter ablation for AF or atrial flutter within 60 days prior to when Amulet 2 device implant procedure would occur
• 8. Inpatient hospitalization due to clinical event or other sequelae within the past 7 days (i.e., not related to planned clinical study procedure or assessments)
• 9. Subject is planning any cardiac or non-cardiac intervention or surgery within 60 days after when Amulet 2 device implant procedure would occur (any intervention or surgery that utilized anesthesia, anesthetic, or sedation), except for study related activities
• 10. Inferior vena cava filter present
• 11. Left ventricular ejection fraction ≤30% (per most recent assessment)
• 12. Experienced stroke or transient ischemic attack within 90 days prior to when Amulet 2 device implant procedure would occur
• 13. Experienced myocardial infarction (with or without intervention) within 90 days prior to when Amulet 2 device implant procedure would occur
• 14. New York Heart Association (NYHA) Class IV Congestive Heart Failure
• 15. Known symptomatic carotid disease (defined as \> 50% lumen diameter narrowing on CTA, MRA, or TCD with symptoms of ipsilateral transient or visual TIA evidenced by amaurosis fugax, ipsilateral hemispheric TIAs or ipsilateral stroke); if subject has a history of carotid stent or endarterectomy the subject is eligible if there is \< 50% lumen diameter narrowing
• 16. Underwent prior attempted endocardial, epicardial, or surgical LAA closure or occlusion, defined as deployment of a device or surgical procedure whether successful or unsuccessful
• 17. Reversible cause of AF (i.e., secondary to thyroid disorders, acute alcohol intoxication, trauma, recent major surgical procedures)
• 18. History of idiopathic or recurrent venous thromboembolism within the past 5 years
• 19. Thrombocytopenia (defined as \< 50,000 platelets per microliter (\<50 x 109/L) or anemia (defined as hemoglobin \< 10 g/dL) requiring transfusions
• 20. Known hypersensitivity to any portion of the device material or individual components of the Amulet 2 device (e.g., nickel allergy)
• 21. Actively enrolled in, or plans to enroll in, a concurrent clinical investigation in which the active treatment arm may confound the results of the VERITAS Study. Each instance must be brought to the attention of the Sponsor to determine eligibility.
• 22. Is pregnant or breastfeeding, or pregnancy is planned during the course of the investigation
• 23. Active endocarditis or other infection producing bacteremia
• 24. Transient case of AF (i.e., never previously detected, provoked/induced by surgical or catheter manipulations, etc.)
• 25. Severe renal failure (estimated glomerular filtration rate \<30 ml/min/1.73m2) or on chronic dialysis
• 26. Life expectancy is less than 2 years in the opinion of the Investigator
• 27. Presence of other anatomic or comorbid conditions, or other medical, social, or psychological conditions that, in the Investigator's opinion, could limit the subject's ability to participate in the clinical investigation or to comply with follow up requirements, or impact the scientific soundness of the clinical investigation results.
