Intraatrial conduction block in the right posteroseptal region after failed accessory pathway ablation—Importance of delineation of three-dimensional pathway geometry
Why the study?
Catheter ablation for accessory pathway-mediated tachycardias still fails in a minority of cases, with incomplete mapping and inaccurate pathway localization being a recognized cause.

Implication
Prolonged ablation near accessory pathways risks local injury and block; this case leaves open optimal 3D mapping strategies.

Intervention
Catheter ablation
O
Outcome
Recurrence of AVRT and intra-atrial conduction block
Prolonged ablation attempts for accessory pathways can cause local tissue injury and intra-atrial conduction block, highlighting the importance of delineating three-dimensional pathway geometry.
