Eligibility
Key inclusion criteria
1. The subject is of legal age to participate in the study per the laws of their
respective geography.

2. Underwent a prior catheter ablation procedure for non-valvular AF between 90 and 180
days prior to randomization (sequential) or is planning to have clinically indicated
catheter ablation within 10 days of randomization (concomitant).

3. The subject has a calculated CHA2DS2-VASc score of 2 or greater for males or 3 or
greater for females.

4. The subject is deemed to be suitable for the defined protocol pharmacologic regimen.

5. The subject is able to undergo TEE examinations.

6. The subject or legal representative is able to understand and is willing to provide
written informed consent to participate in the trial.

7. The subject is able and willing to return for required follow-up visits and
examinations.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. The subject is currently enrolled in another investigational study 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 must be brought to the attention of the sponsor to determine
eligibility, regardless of type of co-enrollment being proposed.

2. The subject requires long-term anticoagulation therapy for reasons other than
AF-related stroke risk reduction, for example due to an underlying hypercoagulable
state (i.e., even if the device is implanted, the subjects would not be eligible to
discontinue OAC due to other medical conditions requiring chronic OAC therapy).

3. The subject is deemed by the treating physician to be unsuitable for chronic
anticoagulation and/or aspirin therapy due to bleeding risk, allergy, or other
reasons.

4. The subject had or is planning to have any cardiac or major non-cardiac interventional
or surgical procedure (excluding non-valvular AF ablation and cardioversion) within 30
days prior to or 60 days after randomization [including, but not limited to:
percutaneous coronary intervention (PCI), other cardiac ablation (VT ablation, etc.),
etc.].

5. The subject had a stroke or transient ischemic attack (TIA) within the 60 days prior
to randomization.

6. The subject had a prior major bleeding event per ISTH definition 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.

7. 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.

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 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)

11. The subject has a documented life expectancy of less than two years.

12. The subject has a cardiac tumor.

13. The subject has signs/symptoms of acute or chronic pericarditis.

14. There is evidence of tamponade physiology.

15. Contraindications (anatomical or medical) to percutaneous catheterization procedures.

16. The subject has documented NYHA Class IV heart failure.

17. The subject has documented surgical closure of the left atrial appendage.

18. The subject has an active infection.
