  • Previous surgical or catheter ablation for AF.
  • Patients known to require ablation outside the PV region
  • Documented severe dilatation of the LA (LAD \>50mm) antero-posterior diameter on imaging within 6 months prior to enrollment.
  • Documented LA thrombus by imaging within 48 hours of the procedure.
  • Documented severely compromised LVEF (\<40%) by imaging within 6 months prior to enrollment
  • Uncontrolled heart failure or New York Heart Association Class III or IV
  • History of blood clotting, bleeding abnormalities or contraindication to anticoagulation (heparin, warfarin, or dabigatran),
  • Documented thromboembolic event (including TIA) within the past 12 months
  • Previous PCI/MI within the past 2 months
  • Coronary Artery Bypass Grafting (CABG) surgery within the past 6 months (180 days)
  • Valvular cardiac surgical/percutaneous procedure
  • Unstable angina within 6 months
  • Anticipated cardiac transplantation, cardiac surgery, or other major surgery within the next 12 months.
  • Significant pulmonary disease or any other disease or malfunction of the lungs or respiratory system that produces severe chronic symptoms.
  • Significant congenital anomaly or medical problem that in the opinion of the investigator would preclude enrollment in this study
  • Prior diagnosis of pulmonary vein stenosis
  • Pre-existing hemi diaphragmatic paralysis
  • Acute illness, active systemic infection, or sepsis
  • Presence of intracardiac thrombus, myxoma, tumor, interatrial baffle or patch or other abnormality that precludes catheter introduction or manipulation.
  • Severe mitral regurgitation
  • Presence of implanted pacemaker or Implantable Cardioverter-Defibrillator (ICD) or other implanted metal cardiac device that may interfere with the IRE energy field.
  • Presence of a condition that precludes vascular access
  • Current enrollment in an investigational study evaluating another device or drug.
