Key result
Cryoballoon ablation produced significantly wider overall lesions (8.2 vs 5.6 mm, P=0.001) and fewer lesion gaps than radiofrequency ablation following pulmonary vein isolation.
Why the study?
Does cryoballoon ablation produce wider and more continuous lesions compared to radiofrequency ablation in patients undergoing pulmonary vein isolation?
Cohort (n=42)

Wider cryoballoon lesions may reduce gaps; hypothesis-generating and requires confirmation in randomized trials.
Kurose et al. (2018) conducted a cohort in Pulmonary vein isolation (n=42). Cryoballoon ablation vs. Conventional radiofrequency ablation was evaluated on Overall lesion width (p=.001). Cryoballoon ablation produced significantly wider overall lesions (8.2 vs 5.6 mm, P=0.001) and fewer lesion gaps than radiofrequency ablation following pulmonary vein isolation.
