About this trial
This is an interventional prevention trial for Atrial Fibrillation focused on measuring Left Atrial Appendage Closure
Eligibility Criteria
Inclusion Criteria:
- 1. Subject must have a documented history of paroxysmal, persistent or permanent nonvalvular atrial fibrillation (AF).
- 2. Subject must be ≥18 years of age.
- 3. Subject has a calculated CHA2DS2-VASc score of 2 or greater.
- 4. Subject must be clinically stable on warfarin (or other anticoagulant) therapy for a minimum of three months.
- 5. Subject must have at least two International Normalized Ratios (INRs); 2-3, if on Warfarin.
- 6. Subject is eligible for the defined protocol pharmacologic regimen of anticoagulation and antiplatelet therapy.
Exclusion Criteria:
- 1. Subject who requires anticoagulation for a condition other than AF.
- 2. Subject with a New York Heart Association (NYHA) classification equal to IV.
- 3. Subject with a history of or implanted atrial septal defect (ASD) device or patent foramen ovale (PFO) device that would interfere with the investigational device placement.
- 4. Subject with valvular disease.
