Key result
3D electroanatomic mapping guides successful ablation of a challenging right posteroseptal AP after conventional failure.
Why the study?
Right posteroseptal accessory pathways in Wolff-Parkinson-White syndrome are often difficult to precisely locate, presenting challenges after an unsuccessful ablation attempt.
Does 3D electroanatomic mapping improve success in difficult accessory pathway ablation in patients with Wolff-Parkinson-White syndrome?

Does 3D electroanatomic mapping improve success in difficult accessory pathway ablation in patients with Wolff-Parkinson-White syndrome?
Advanced three-dimensional cardiac mapping systems play an important role in precisely locating and safely ablating challenging accessory pathways in Wolff-Parkinson-White syndrome.
May aid ablation of challenging WPW pathways after conventional failure; hypothesis-generating, requiring prospective confirmation before practice change.
This is a challenging case of Wolff–Parkinson–White syndrome which was located in the right posteroseptum region. Patient had a previous unsuccessful attempt at ablation. It is often difficult to precisely locate this type of accessory pathway. A repeat procedure using 3D electroanatomic mapping, the electroanatomic geometry of the heart was created. The accessory pathway potential was identified and the accessory pathway was successfully ablated in minimum amount of time. In this case report showed that the advanced three-dimensional cardiac mapping system plays a very important role in guiding clinicians in order to precisely locate and safely ablate this type of challenging accessory pathway.

Bala et al. (2023) conducted a case report in Wolff-Parkinson-White syndrome (n=1). 3D electroanatomic mapping-guided radiofrequency ablation vs. Conventional mapping was evaluated on Successful ablation of accessory pathway. Three-dimensional electroanatomic mapping successfully guided the precise localization and rapid ablation of a challenging right posteroseptal accessory pathway after a failed conventional attempt.
