Do anatomical variables predict acute and mid-term success of cryoballoon ablation of atrial fibrillation using the 28 mm balloon?
Anatomical variables that prevent maximal heat transfer can predict failure of cryoballoon pulmonary vein isolation, suggesting a role for tailored ablation strategies based on individual anatomy.
Anatomical variables preventing maximal heat transfer from the tissue to the CB could be identified as predictors for CB-PVI failure with the 28 mm balloon. These findings may be a step toward a more tailored ablation strategy based on individual anatomical variations.
