Key characteristics for effective acute pulmonary vein isolation when using a novel cryoballoon technology: insights from the CHARISMA registry

ConclusionsThe new POLARx ™ CB appears to be effective and safe. A nadir temperature of − 56 °C, a thaw time to 0 °C ≥ 17 s, and complete PV occlusion were the best predictors of acute PV isolation.Clinical trial registrationCatheter Ablation of Arrhythmias with a High-Density Mapping System in Real-World Practice (CHARISMA).
