Acute procedural efficacy and safety of a novel cryoballoon for the treatment of paroxysmal atrial fibrillation: results from the POLAR ICE study.

This real-world usage data on a novel cryoballoon suggests this device is effective, safe, and relatively fast in centers with cryoballoon experience. These data are comparable to prior POLARx reports and in keeping with reported data on other cryoballoons. Future studies should examine the long-term outcomes and the relationship between biophysical parameters and outcomes for this novel cryoballoon. This article is protected by copyright.
