Primary Outcome Measures:
  • Effectiveness [ Time Frame: Through 36 months ] [ Designated as safety issue: No ]

    Evaluated by assessing the rate of subjects free of chronic treatment failure with paroxysmal atrial fibrillation who have failed one or more Atrial Fibrillation Drugs (AFDs).

    Chronic treatment failure is defined as:

    • Documented atrial fibrillation lasting longer than 30 seconds (outside the 90 day blanking period) OR
    • Intervention for atrial fibrillation (except for repeat cryoablation during the 90 day blanking period)

  • Safety [ Time Frame: 12 Months ] [ Designated as safety issue: Yes ]
    Demonstrate safety (through 12 months) of Arctic Front® Cardiac CryoAblation Catheter System, including the Freezor® MAX Cardiac Cryoablation Catheter by assessing the rate of subjects experiencing Cryoablation Procedure Events (CPEs) with paroxysmal atrial fibrillation who have failed one or more Atrial Fibrillation Drugs (AFDs).


Secondary Outcome Measures:
  • Chronic Safety [ Time Frame: Annually, through 5 years ] [ Designated as safety issue: Yes ]
    Freedom from Major Atrial Fibrillation Event (MAFE): A MAFE is a serious adverse event (SAE) which has not been categorized as a cryoablation procedure event.

  • Chronic Effectiveness [ Time Frame: Annually, through 5 years ] [ Designated as safety issue: No ]

    Freedom from chronic treatment failure, defined as:

    • Documented atrial fibrillation lasting longer than 30 seconds (outside the 90 day blanking period) OR
    • Intervention for atrial fibrillation (except for repeat cryoablation during the 90 day blanking period)


Estimated Enrollment: 400
Study Start Date: May 2012
Estimated Study Completion Date: January 2020
Estimated Primary Completion Date: January 2018 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Medtronic Arctic Front® Cardiac CryoAblation System
    Cardiac cryoablation to isolate the pulmonary veins using the Arctic Front® CryoAblation System, with point ablation using the Freezor® Max as needed.
    Other Names:
    • Medtronic CryoCath CryoConsole
    • Arctic Front® Cardiac CryoAblation Catheter
    • Arctic Front Advance™ Cardiac CryoAblation Catheter
    • Freezor® MAX Cardiac CryoAblation Catheter
Detailed Description:

Safety and effectiveness will be evaluated against pre-specified performance criteria as determined by the sponsor and FDA. The criteria set in this study have been previously used to demonstrate safety and effectiveness in cryoablation and radio-frequency ablation for the treatment of paroxysmal atrial fibrillation.

The analyses of the primary effectiveness objective will take place once all the subjects with a study cryoablation procedure attempt have reached 36 months of follow-up post-cryoablation procedure. The analysis of the primary safety objective will take place once all the subjects with a study cryoablation procedure attempt have reached 12 months of follow-up post-cryoablation procedure. The analyses for the secondary objectives will take place once all subjects with a study cryoablation attempt have reached 60 months of follow-up post-cryoablation procedure.
