Acute procedural efficacy and safety of a novel cryoballoon for the treatment of paroxysmal atrial fibrillation: Results from the POLAR ICE study
Key result
A novel cryoballoon achieved complete pulmonary vein isolation in 96.8% of targeted pulmonary veins during de novo procedures for paroxysmal atrial fibrillation.
Why the study?
Real-world acute procedural efficacy and safety data were needed for a novel cryoballoon used for pulmonary vein isolation in paroxysmal atrial fibrillation.
Does a novel cryoballoon safely and effectively achieve pulmonary vein isolation in patients with paroxysmal atrial fibrillation?
Population
399 patients with paroxysmal AF across 19 European centers
Comparison
Pulmonary vein isolation using a novel cryoballoon
Design
Prospective, non-randomized, multicenter international registry
