Key result
The exclusive use of a novel 25-mm circular mapping catheter for cryoballoon ablation of atrial fibrillation resulted in a real-time pulmonary vein recording rate of 80% and acute isolation of 98% of targeted veins.

The use of a novel 25-mm circular mapping catheter during cryoballoon ablation for atrial fibrillation is safe and provides a high rate (80%) of real-time pulmonary vein recordings to guide therapy.
Reißmann et al. (2017) conducted an observational in Symptomatic paroxysmal or persistent atrial fibrillation (n=40). 25-mm circular mapping catheter (Achieve Advanced) was evaluated on Rate of real-time recordings of cryoballoon-based pulmonary vein isolation (95% CI 73-86). The exclusive use of a novel 25-mm circular mapping catheter for cryoballoon ablation of atrial fibrillation resulted in a real-time pulmonary vein recording rate of 80% and acute isolation of 98% of targeted veins.
