Eligibility Criteria:
Inclusion Criteria:
* Patients 18 years of age or older candidates for a first AF ablation
* Symptomatic AF, refractory to at least one antiarrhythmic medication
* Persistent or long-standing persistent AF with documentation of (ECG, Holter, physician's letter): AF duration of ≥ 3 months and ≤ 5 years (≥ 3 months and \< 1 year in the United States) or 1 effective cardioversion followed by AF recurrence lasting ≥ 3 months
* Continuous anticoagulation with warfarin (INR 2-3) or NOAC for \> 4 weeks prior to ablation
* Patients must be able and willing to provide written informed consent to participate in the clinical trial
* At least 60% of patients (224 patients) in persistent AF ≥ 6 months including at least 15% (56 patients) of long-standing persistent AF ≥ 12 months
Exclusion Criteria:
* Paroxysmal and short-standing AF \< 3 months
* Long-standing persistent AF \> 5 years (≥ 1 year in the United States)
* ≥ 2 previous ineffective cardioversion sessions in case of undetermined AF duration
* Severe obesity (BMI \> 40)
* Very dilated Left Atrium (LA)(e.g. LA diameter \> 60 mm and/or LA surface \> 40 cm2 determined by 2D echocardiography)
* Patients with AF secondary to an obvious reversible cause
* Inadequate anticoagulation as defined in the inclusion criteria
* LA thrombus on Transesophageal Echocardiography (TEE) or CT Scan prior to procedure
* Contraindications to anticoagulation (heparin, warfarin or NOAC)
* Patients who are or may potentially be pregnant
* Previous surgical or catheter ablation for AF
* Any cardiac surgery within the past 2 months (60 days) (includes PCI)
* Myocardial infarction within the past 2 months (60 days)

* Unstable angina within the past month
* Acute illness or active systemic infection or sepsis
* AF secondary to electrolyte imbalance, thyroid disease, or reversible or non-cardiac cause
* Diagnosed atrial myxoma
* Significant severe pulmonary disease, (e.g. patients with restrictive pulmonary disease, constrictive or chronic obstructive pulmonary disease in GOLD stage IV) or any other disease or malfunction of the lungs or respiratory system that produces chronic symptoms (e.g. unstable or untreated sleep apnea)
* Significant congenital anomaly or medical problem that in the opinion of the investigator would preclude enrollment
* Enrollment in an investigational study evaluating another device, biologic, or drug
* Presence of intramural thrombus, tumor or other abnormality or condition that precludes vascular access, or manipulation of the catheter
* Life expectancy or other disease processes likely to limit survival to less than 12 months
