Radiofrequency Current Catheter Ablation of Accessory Atrioventricular Pathways in Ebstein's Anomaly

Abstract

In patients with Ebstein's anomaly and reentrant atrioventricular tachycardias, factors likely to account for failure of RF catheter ablation include an AP located along the atrialized right ventricle and the abnormal morphology of endocardial activation potentials generated in this region.
