Outcome Measures
Primary Outcomes (2)
Number of Participants With Early Onset Primary Adverse Events
The primary safety endpoint was the incidence of early-onset primary adverse events within 7 days post the AF ablation procedure; Pulmonary vein stenosis and atrio-esophageal fistula that occurred beyond 7 days post-procedure and development of a significant pericardial effusion within 30 days post-procedure were also considered primary AEs
30 days post-procedure
Incidence of Early Onset Primary Adverse Events for the Intent-to-Treat and As-Treated Population
The primary safety endpoint was the incidence of early-onset primary adverse events within 7 days post the AF ablation procedure; Pulmonary vein stenosis and atrio-esophageal fistula that occurred beyond 7 days post-procedure and development of a significant pericardial effusion within 30 days post-procedure were also considered primary AEs

Eligibility Criteria
You may qualify if:
- Patients with symptomatic paroxysmal AF who have had at least one AF episode documented within one (1) year prior to enrollment. Documentation may include ECG, transtelephonic monitor (TTM), Holter monitor (HM), or telemetry strip.
- Patients who have failed at least one antiarrhythmic drug (AAD; class I or III, or atrioventricular (AV) nodal blocking agents such as beta blockers and calcium channel blockers) as evidenced by recurrent symptomatic AF, or intolerance to the AAD.
- Pre-procedure anticoagulation on warfarin, rivaroxaban, or apixaban.
- Age 18 years or older.
- Signed Patient Informed Consent Form (ICF).
- Able and willing to comply with all pre-, post-, and follow-up testing and requirements.
You may not qualify if:
- AF secondary to electrolyte imbalance, thyroid disease, or reversible or non-cardiac cause.
- Previous ablation for atrial fibrillation.
- Patients on amiodarone at any time during the past 3 months prior to enrollment.
- AF episodes lasting \> 7 days.
- Any cardiac surgery within the past 60 days (2 months).
- Any valvular cardiac surgical procedure (i.e., ventriculotomy, atriotomy, and valve repair or replacement and presence of a prosthetic valve).
- Coronary artery bypass graft (CABG) procedure within the last 180 days (6 months).
- Awaiting cardiac transplantation or other cardiac surgery within the next 365 days (12 months).
- Documented left atrial thrombus on imaging.
- History of a documented thromboembolic event within the past one (1) year.
- Diagnosed atrial myxoma.
- Presence of implanted cardioverter defibrillator (ICD).
- 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.
- Significant congenital anomaly or medical problem that in the opinion of the investigator would preclude enrollment in this study.
- Women who are pregnant (as evidenced by pregnancy test if subject is of child-bearing age and potential) or breast feeding.
