Outcome Measures

Primary Outcomes (2)

  • Freedom from Atrial Fibrillation (AF) /Atrial Flutter (AFL) /Atrial Tachycardia (AT)

    Estimate the 36-month freedom from Atrial Fibrillation (AF) /atrial flutter (AFL) /Atrial Tachycardia (AT) recurrence using the Arctic Front™ cardiac cryoablation catheter System.

    36 months

  • Freedom from Primary Safety Events

    Estimate primary safety Adverse Event (AE) rates for cryoablation using the Arctic Front™ cardiac cryoablation catheter System through 12-months.

    12 months

Interventions

Pulmonary vein isolation will be performed with the Arctic Front™ cardiac cryoablation catheter system

Sampling MethodNon-Probability Sample
Study Population

Subjects ≥ 18 years of age (or minimum age as required by local regulations) who have a recommendation for a pulmonary vein ablation with the Arctic Front™ cardiac cryoablation catheter System.

You may qualify if:

  • Subject has been diagnosed with symptomatic paroxysmal AF
  • Subject is ≥ 18 years of age or minimum age as required by local regulations
  • Planned pulmonary vein isolation (PVI) procedure using the commercially available Arctic Front™ cardiac cryoablation catheter System.
  • Willing to comply with study requirements and give informed consent (defined as legally effective, documented confirmation of a subject's voluntary agreement to participate in this clinical study) or authorization per institution and geographical requirements

You may not qualify if:

  • History of AF treatment with a class I or III antiarrhythmic drug, including sotalol, with the intention to prevent an AF recurrence1
  • Subjects under the following conditions may be included in the study:
  • Temporary treatment with a class I or III AAD (treatment at a therapeutic dose for a period of \<4 weeks prior to the index PVI procedure)
  • Recent treatment with a class I or III AAD (within 6 months of the index PVI procedure) at a dose below therapeutic threshold according to the AHA/ACC/HRS Guideline for the Management of Patients with Atrial Fibrillation
  • A subject who has received a chemical cardioversion may be included in the study. This includes a chemical cardioversion prior to enrollment and between enrollment and ablation.
  • Subject has had a prior atrial ablation (except for cavo-tricuspid isthmus (CTI) ablation for AFL)
  • Subject is enrolled in a concurrent study that has not been approved for concurrent enrollment by the global study manager
