Key result
Transcutaneous epicardial ablation successfully eliminates resistant posteroseptal accessory pathway after failed endocardial attempts.
Why the study?
Treatment options for posteroseptal accessory pathways resistant to conventional endocardial and coronary venous system ablation are limited.
Does transcutaneous epicardial radiofrequency ablation successfully treat a resistant posteroseptal accessory pathway in a patient with Wolff-Parkinson-White syndrome?

Does transcutaneous epicardial radiofrequency ablation successfully treat a resistant posteroseptal accessory pathway in a patient with Wolff-Parkinson-White syndrome?
Transcutaneous epicardial radiofrequency ablation can be a successful alternative for treating resistant posteroseptal accessory pathways in Wolff-Parkinson-White syndrome when conventional approaches fail.
Pericardial ablation may succeed after endocardial failure in refractory WPW; single case leaves open prospective validation.
A case of Wolff-Parkinson-White syndrome successfully treated by transcutaneous epicardial radiofrequency ablation is described in a patient with a posteroseptal accessory pathway who had failed prior attempts of conventional endocardial and coronary venous system approaches. Simultaneous endocardial and pericardial space mapping was performed and only ablation from the pericardial space was successful, suggesting an epicardial course of the accessory pathway.

Paola et al. (2004) conducted a case report in Wolff-Parkinson-White syndrome (n=1). Transcutaneous epicardial radiofrequency ablation vs. Prior conventional endocardial and coronary venous system approaches was evaluated on Successful ablation of the accessory pathway. Transcutaneous epicardial radiofrequency ablation successfully treated a resistant posteroseptal accessory pathway in a patient who failed prior conventional endocardial approaches.
