Primary Outcome Measures:
  • Freedom from symptomatic AF during nine months following the blanking period [ Time Frame: 12 Months ] [ Designated as safety issue: No ]
  • Confirmation of entrance block in the pulmonary veins [ Time Frame: During the procedure ] [ Designated as safety issue: No ]
  • Incidence of adverse events included in the pre-specified composite [ Time Frame: 7 days ] [ Designated as safety issue: Yes ]
  • Incidence of adverse events included in the pre-specified composite. [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Documented (> 30 seconds) asymptomatic episodes of AF, AFL or AT after the blanking period [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  • Early onset (within 90 days) of SAE/Non-serious AEs and late onset (after 90 days) SAEs [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Age 18 years or older
  • Signed Patient Informed Consent Form
  • Able and willing to comply with all pre-, post-, and follow-up testing and requirements
  • Failure of at least one anti-arrhythmic medication (AAD) for paroxysmal atrial fibrillation* [class I or III, or AV nodal blocking agents such as beta blockers (BB) and calcium channel blockers (CCB)] as evidenced by recurrent symptomatic paroxysmal atrial fibrillation*, or intolerable side effects due to AAD
  • Subjects with symptomatic paroxysmal atrial fibrillation*

    • Paroxysmal AF is defined as recurrent AF that terminates spontaneously within seven days.

Exclusion Criteria:

  • AF secondary to electrolyte imbalance, thyroid disease, or reversible or non-cardiac cause
  • Previous ablation for AF
  • History of any valvular cardiac surgical procedure
  • CABG procedure within the last six months
  • Awaiting cardiac transplantation or other cardiac surgery within the next 12 months
  • Left atrial thrombus
  • History of a documented thromboembolic event within the past one (1) year
  • Diagnosed atrial myxoma
  • An implanted 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 (by history of menstrual period or pregnancy test if the history is considered unreliable)
  • Acute illness or active systemic infection or sepsis
  • Unstable angina
  • Myocardial infarction within the previous two months
  • Left ventricular ejection fraction (LVEF) <40% as determined by pre-procedure TTE
  • History of blood clotting or bleeding abnormalities
  • Contraindication to anticoagulation (i.e. heparin or warfarin)
  • Contraindication to computed tomography/magnetic resonance angiography (CT/MRA) procedure
  • Life expectancy less than 12 months
  • Enrollment in an investigational study evaluating another device or drug
  • Uncontrolled heart failure or NYHA class III or IV heart failure
  • An intramural thrombus tumor, or other abnormality that precludes catheter introduction or manipulation
  • Presence of a condition that precludes vascular access
  • Left atrial size ≥ 50 mm as determined by pre-procedure TTE
