Brief Summary   The Arctic FrontTM Family of Cardiac CryoAblation Catheters are used for the treatment of patients with atrial fibrillation (AF). These catheters facilitate anatomical isolation of the pulmonary veins from the left atrium with the application of a 23mm or 28mm cryoballoon at the pulmonary vein ostium. The cryoballoon ablates with minimal disruption of the endothelium, creates relatively discrete lesions, and preserves the myocardial architecture, followed by replacement with fibrous tissue through the Joule-Thomson effect.

The Freezorâ„¢ Family of Cardiac Cryoablation Catheters are used for the focal cryoablation of cardiac tissue to treat cardiac arrhythmias.

Approved indications for use for each market-released product are defined in the respective labeling for each geography.

This clinical study has been designed to provide valid scientific evidence on the safety and effectiveness of the Arctic Frontâ„¢ and Freezorâ„¢ Families of Cardiac Cryoablation Catheters (hereafter referred to as Arctic Frontâ„¢ Cardiac Cryoablation Catheter System) in a global setting. Previous clinical studies have reported on safety and efficacy of these devices. Medtronic has published numerous studies including the STOP AF Post-Approval Study, Cryo4Persistent AF, ICY-AVNRT, and STOP AF First. There are also several investigator-initiated single center publications.

The Cryo Global Registry is a prospective, global, multi-center, observational post-market registry. The purpose of this registry is to describe clinical performance and safety data in a broad patient population treated with Arctic Frontâ„¢ Cardiac Cryoablation Catheter System. To assess clinical performance and safety of the system, study objectives will estimate 12-month efficacy and procedural safety. Additionally, study objectives will characterize the ablation procedure, Quality of Life (QoL), and global standard of care for AF ablation patients having cryoablation.
