Cryoballoon ablation

Designed for pulmonary vein isolation (PVI), the Medtronic cryoballoon ablation system offers an anatomical approach to addressing atrial arrhythmias, creating wide antral, contiguous circumferential lesions surrounding the target anatomy.

Multiple Arctic Front™ cryoballoons against a blue background

Safe, simple, and effective AF ablation procedures

The Arctic Front™ cryoablation system is the leader in cryoballoon technology with over 17 years of clinical experience, treating more than one million patients worldwide.1

The Arctic Front™ family of cryoballoons enables safe, effective, and efficient procedures. The Arctic Front™ system provides physicians with a straightforward approach to PVI with minimal applications, durable lesions, and delivering consistent and predictable results,2 for first-line, paroxysmal, and persistent AF patients.3-6

Arctic Front™ benefits

  • High PVI occlusion rates with single-shot freeze9-11
  • Uniform ice cap homogeneity and continuous lesion formation12
  • Strong safety profile with low rates of serious adverse events13
  • Consistent and predicable procedure outcomes2

The Medtronic cryoablation system includes the Freezor™ family of cryoablation catheters, which include devices approved for the treatment of AF or pediatric and adult AVNRT.7,8

Early rhythm control with Arctic Front™ cryoballoon

The Medtronic Arctic Front™ cryoballoon system is the only ablation system FDA-approved as an initial rhythm control strategy for patients with paroxysmal atrial fibrillation. It is also indicated for the treatment of paroxysmal and persistent* AF patients.

Meta-analysis of three randomized first-line trials, STOP AF First, EARLY-AF, and Cryo-FIRST, demonstrates cryoablation is more effective than antiarrhythmic drugs as an initial first-line therapy for patients with paroxysmal AF.​14

  • 74.6% freedom from atrial arrhythmia recurrence in the cryoballoon arm, versus
  • 45% in the antiarrhythmic drug arm
  • 39% relative reduction in the risk of atrial arrhythmia recurrence1
  • 8.32 points larger improvement in AFEQT score on average1
  • 29% relative reduction in healthcare utilization1
  • 62% relative reduction in hospitalization1
