Key result
Cryoballoon ablation is reviewed as an alternative to radiofrequency ablation for paroxysmal atrial fibrillation, highlighting a current lack of randomized trial data comparing the two techniques.
Why the study?
Does cryoballoon ablation improve acute success, efficiency at follow-up, and safety compared to radiofrequency ablation in patients with paroxysmal atrial fibrillation?
Does cryoballoon ablation improve acute success, efficiency at follow-up, and safety compared to radiofrequency ablation in patients with paroxysmal atrial fibrillation?
This review compares the acute success, follow-up efficiency, and safety of radiofrequency versus cryoballoon ablation for paroxysmal atrial fibrillation.
Absence of randomized comparisons leaves cryoballoon versus radiofrequency ablation choice unresolved; trials needed to guide paroxysmal AF practice.
Pulmonary vein isolation is the cornerstone of paroxysmal atrial fibrillation ablation. Radiofrequency (RF) ablation is currently the most widespread technique. Recently, cryoballoon ablation has emerged as an alternative to RF ablation for paroxysmal atrial fibrillation. Until now there are no data from randomized trial comparing these two techniques. The purpose of this report was to review the pulmonary vein isolation acute success, the efficiency at follow-up and the safety of these two ablation strategies. Additionally, some considerations are made concerning the contact-force sensing RF catheters and the second-generation cryoballoon.

Sousa et al. (2015) conducted a review in Paroxysmal atrial fibrillation. Cryoballoon ablation vs. Radiofrequency ablation was evaluated on Pulmonary vein isolation acute success, efficiency at follow-up, and safety. Cryoballoon ablation is reviewed as an alternative to radiofrequency ablation for paroxysmal atrial fibrillation, highlighting a current lack of randomized trial data comparing the two techniques.
