Catheter inversion technique successfully eliminated a parahisian accessory pathway that could not be ablated by a direct approach using repeated high-energy ablation.
A catheter inversion technique may be an alternative for ablating parahisian accessory pathways when a direct approach fails.

May offer bailout for refractory parahisian pathways; hypothesis-generating and requires prospective validation before wider use.
Parahisian accessory pathways are generally superficial and can be successfully ablated using a direct approach in the great majority of cases with only rare complications. Our case is unusual because even though it was superficially located on the endocardium, it could not be eliminated by a direct approach using repeated high-energy ablation. Instead, it …
