The lesion characteristics assessed by LGE‐MRI after the cryoballoon ablation and conventional radiofrequency ablation

摘要

BackgroundRhythm outcomes after the pulmonary vein isolation (PVI) using the cryoballoon (CB) are reported to be excellent. However, the lesions after CB ablation have not been well discussed. We sought to characterize and compare the lesion formation after CB ablation with that after radiofrequency (RF) ablation.
