Primary Outcome Measures:
  • AF/AT/Atrial Flutter(AFL) free absent class I and III AADs except for a previously failed or intolerant class I or III AAD with no increase in dosage. [ Time Frame: 12 Months ] [ Designated as safety issue: No ]
    The primary efficacy endpoint is success or failure to be AF/AT/AFL free absent class I and III AADs except for a previously failed or intolerant class I or III AAD with no increase in dosage following the 3 month blanking period through the 12 months post procedure follow-up visit.
