Evaluation of the direction and extent of ice formation during cryoballoon ablation: an experimental study

ConclusionsIce formation was significantly greater on the lower side of the cryoballoon than on the upper side and extended to the proximal hemisphere of the balloon, which might facilitate the acquisition of a wide ablation area on the left atrial posterior wall after cryoballoon ablation.Graphical AbstractDifferent ice formation after cryoballoon ablationGreater ice formation on the lower side of cryoballoon and an extensive ice formation in the proximal hemisphere, especially in novel cryoballoon.
