Primary Outcome Measures:
  • Freedom from documented symptomatic atrial fibrillation (AF), atrial tachycardia (AT), or atrial flutter (AFL) episodes through 12-month follow-up [ Time Frame: 12-months ] [ Designated as safety issue: No ]
    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).

  • Incidence of early onset (within 7 days of the AF ablation procedure) primary adverse events. [ Time Frame: 7 days of the AF ablation procedure ] [ Designated as safety issue: Yes ]
    The primary safety endpoint will be the incidence of early onset (within 7 days of the AF ablation procedure) primary adverse events.


Secondary Outcome Measures:
  • Acute Success [ Time Frame: End of procedure ] [ Designated as safety issue: No ]
  • Peri-procedural SAEs [ Time Frame: Less than or equal to 30 days post procedure ] [ Designated as safety issue: Yes ]
  • Late onset SAEs [ Time Frame: Greater than 30 days post procedure ] [ Designated as safety issue: Yes ]
