5. Able and willing to comply with all pre-, post-, and follow-up testing and requirements
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Continuous AF > 12 months (longstanding persistent AF)
2. Previous left atrial surgical or catheter ablation for atrial fibrillation or a previous procedure that required an incision in the left atrium with resulting scar
3. Any cardiac procedure (surgical or percutaneous) within 90-days prior to the initial procedure
4. CABG surgery within the 6-months (180-days) prior to the initial procedure
5. Valvular cardiac surgical/percutaneous procedure (i.e. ventriculotomy, valve repair or replacement and/or presence of a prosthetic or mechanical valve)
6. Any carotid stenting or endarterectomy
7. Documented or known left atrial thrombus on imaging
8. Left atrial diameter > 50 mm (parasternal long axis view or by CT)
9. Left ventricular ejection fraction < 40%
10. Unable to take anticoagulation medication due to contraindication or intolerance
11. History of blood clotting or bleeding abnormalities
12. Myocardial infarction (MI), acute coronary syndrome, percutaneous coronary intervention (PCI) within the 3-months (90-days) prior to the initial procedure
13. Documented thromboembolic event (including TIA) within the 12-months (365 days) prior to the initial procedure
14. Rheumatic heart disease
15. Uncontrolled heart failure or NYHA functional class III or IV
16. Severe mitral regurgitation (regurgitant volume = 60 mL/beat, regurgitant fraction = 50%, and/or effective regurgitant orifice area = 0.40cm2)

18. Unstable angina at the time of the initial procedure
19. Acute illness or active systemic infection or sepsis

21. Diagnosed atrial myxoma
22. Presence of implanted implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy-defibrillator (CRT-D)
23. Significant pulmonary disease, (e.g., restrictive pulmonary disease, constrictive or chronic obstructive pulmonary disease) or any other disease or malfunction of the lungs or respiratory system that produces chronic symptoms
24. Significant congenital anomaly or other anatomic or comorbid medical problem that in the opinion of the investigator would preclude enrollment in this study or compliance with the follow-up requirements or impact the scientific soundness of the clinical trial results
25. Pregnant or nursing subjects and those who plan pregnancy during the clinical investigation follow-up period
26. Enrollment in an investigational study evaluating another device, biologic, or drug that may interfere with this clinical investigation at the time of the initial procedure or within 30 days prior to the initial procedure
