A long slanted transseptal accessory pathway

Abstract

A 63-year-old male with Wolff-Parkinson-White syndrome was admitted for ablation of accessory pathway. Intracardiac electrogram revealed a left-side accessory pathway during tachycardia, which was successfully ablated from the right posterior tricuspid annulus because of a long slanted transseptal accessory pathway (2.2 cm).
