Implication
May support comparable mid-term efficacy of cryoballoon versus radiofrequency ablation in paroxysmal AF; hypothesis-generating and leaves open randomized confirmation.
Structured PICO
Does cryoballoon ablation prevent relapse similarly to radiofrequency ablation in patients with paroxysmal atrial fibrillation?
P
Population
687 consecutive patients with paroxysmal atrial fibrillation undergoing a first procedure of catheter ablation.
I
Intervention
Cryoballoon ablation (Arctic Front™ or Arctic Front Advance™)
C
Comparator
Radiofrequency ablation
O
Outcome
Incidence of relapse and safety endpoints at mean 14 ± 8 months follow-up, evaluated according to pulmonary vein anatomical variants
Cryoballoon ablation has similar mid-term efficacy to radiofrequency ablation for paroxysmal atrial fibrillation, and its success is not compromised by pulmonary vein anatomical variants.
