Outcome Measures

Primary Outcomes (2)

  • Effectiveness: Percentage of Participants Free of Chronic Treatment Failure (CTF) Through 36 Months

    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)

    Through 36 months

  • Safety: Percentage of Participants Experiencing Cryoablation Procedure Events (CPEs) Through 12 Months

    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).

    12 Months

Secondary Outcomes (2)

  • Chronic Safety: Percentage of Participants Free From Major Atrial Fibrillation Events (MAFE) at 1, 2 and 3 Years.

    Annually, through 3 years

  • Chronic Effectiveness: Percentage of Participants Free of Chronic Treatment Failure (CTF) at 1 and 2 Years

    Annually, at 1 and 2 years

Study Arms (1)

Single Arm

OTHER

Cryoablation

Device: Medtronic Arctic Front® Cardiac CryoAblation System

Interventions

Cardiac cryoablation to isolate the pulmonary veins using the Arctic Front® CryoAblation System, with point ablation using the Freezor® Max as needed.

Also known as: Medtronic CryoCath CryoConsole, Arctic Front® Cardiac CryoAblation Catheter, Arctic Front Advance™ Cardiac CryoAblation Catheter, Freezor® MAX Cardiac CryoAblation Catheter
Single Arm

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Documented PAF:
  • Diagnosis of paroxysmal atrial fibrillation (PAF), AND

  • At least 1 episode of AF documented with a tracing within 12 months preceding the consent date.
  • Age 18 years or older
  • Failure for the treatment of AF (effectiveness or intolerance) of at least one membrane active AAD for rhythm control.

You may not qualify if:

  • Any previous left atrial (LA) ablation (except permissible retreatment subjects)
  • Any previous LA surgery
  • Current intracardiac thrombus (can be treated after thrombus is resolved)
  • Presence of any pulmonary vein stents
  • Presence of any pre-existing pulmonary vein stenosis
  • Pre-existing hemidiaphragmatic paralysis
  • Anteroposterior LA diameter \> 5.5 cm by TTE
  • Presence of any cardiac valve prosthesis
  • Clinically significant mitral valve regurgitation or stenosis
  • Myocardial infarction, PCI / PTCA or coronary artery stenting which occurred during the 3 month interval preceding the Consent Date
  • Unstable angina
  • Any cardiac surgery which occurred during the 3 month interval preceding the Consent Date
  • Any significant congenital heart defect corrected or not (including atrial septal defects or pulmonary vein abnormalities but not including minor PFO)
  • NYHA class III or IV congestive heart failure
  • Left ventricular ejection fraction (LVEF) \< 40%
  • +14 more criteria
