Key result
Radiofrequency catheter ablation successfully localized and ablated a right posteroseptal accessory pathway in a young man with Wolff-Parkinson-White syndrome and dextroversion.
Case Report (n=1)
Successful radiofrequency ablation of a right posteroseptal accessory pathway in a patient with dextroversion helped define the specific electrocardiographic modifications for this rare presentation.
Supports ablation feasibility in WPW with dextroversion; leaves open validation of ECG criteria in larger series.
We report an observation of a radiofrequency catheter ablation of an accessory pathway (AP) in a patient with Wolff-Parkinson-White syndrome (WPW) and dextroversion. Atrioventricular rings were mapped by the ablation catheter to locate the shortest local atrioventricular conduction time in sinus rhythm and ventriculoatrial conduction time during orthodromic tachycardia or ventricular pacing. Successful ablation confirmed a right posteroseptal AP localization. Thus, the electrocardiographic modifications due to an AP in this location in the presence of dextroversion were defined.

Klug et al. (1994) conducted a case report in Wolff-Parkinson-White syndrome and dextroversion (n=1). Radiofrequency catheter ablation was evaluated on Successful ablation of accessory pathway. Radiofrequency catheter ablation successfully localized and ablated a right posteroseptal accessory pathway in a young man with Wolff-Parkinson-White syndrome and dextroversion.
