Inclusion Criteria

• Subjects with symptomatic atrial fibrillation (AF) who, in the opinion of the investigator, are candidates for ablation for atrial fibrillation. Candidates who have had previous ablation procedures may be included in the registry
• Subjects who have failed at least one antiarrhythmic drug (AAD)(class I or III, or AV nodal blocking agents such as beta blockers and calcium channel blockers) as evidenced by recurrent symptomatic atrial fibrillation, or intolerable to the AAD.
• Subjects must be 18 years of age or older

• History of a documented thromboembolic event within the past year
• Significant pulmonary disease (eg, 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
• Previous cardiac surgery (eg, CABG) or valvular cardiac surgical procedure (eg, ventriculotomy, atriotomy, valve repair or replacement, presence of a prosthetic valve)
• Awaiting cardiac transplantation or other cardiac surgery within the next 360 days (12 months)
• Diagnosed atrial myxoma
• Unstable angina
• Uncontrolled heart failure Uncontrolled heart Failure or NYHA Class III or IV heart failure
• Acute illness, active systemic infection, or sepsis
• Any other disease or malfunction that would preclude treatment with ablation in the opinion of the investigator
