Arm Intervention/treatment
AF Ablation

Primary Outcome Measures :
  1. The Rate of Subjects Who Were Free From Documented Symptomatic Atrial Fibrillation (AF), Atrial Tachycardia (AT), or Atrial Flutter (AFL) Episodes Through 12-month Follow-up [ Time Frame: 12-months ]
    The primary effectiveness endpoint for this study will be freedom from documented symptomatic atrial fibrillation (AF), atrial tachycardia (AT), or atrial flutter (AFL) episodes through 12-month follow-up (includes a three month blanking period).

  2. Incidence of Early Onset (Within 7 Days of the AF Ablation Procedure) Primary Adverse Events. [ Time Frame: 7 days of the AF ablation procedure ]
    Primary adverse events (AE) include Death, Myocardial infarction (MI), Pulmonary vein (PV) stenosis, Diaphragmatic paralysis, Atrio-esophageal fistula, Transient Ischemic Attack (TIA), Stroke / Cerebrovascular accident (CVA), Thromboembolism, Pericarditis, Cardiac Tamponade, Pericardial effusion, Pneumothorax, Atrial perforation, Vascular Access Complications, Pulmonary edema, Hospitalization (initial and prolonged), and Heart block.

Secondary Outcome Measures :
  1. Rate of Acute Success [ Time Frame: End of procedure ]
    Acute success is defined as confirmation of entrance block in all Pulmonary veins (PV).
