Atrial double potentials associated with a left‐sided accessory pathway having a single ventricular and two remote atrial insertions

This paper reports the case of a 63‐year‐old female patient with Wolff‐Parkinson‐White syndrome who underwent an electrophysiologic study (EPS) and ablation using temperature‐guided radiofrequency current for atrial fibrillation with a shortest preexcited RR interval of 160 ms. Detailed EPS and mapp...

Description
Summary:	This paper reports the case of a 63‐year‐old female patient with Wolff‐Parkinson‐White syndrome who underwent an electrophysiologic study (EPS) and ablation using temperature‐guided radiofrequency current for atrial fibrillation with a shortest preexcited RR interval of 160 ms. Detailed EPS and mapping demonstrated an unusual, complex left‐sided accessory pathway, with the two distinct branches having two remote atrial insertions and a narrow common ventricular isthmus associated with the manifestation of atrial double potentials recorded from the coronary sinus. Simple ablation at the left lateral side from the ventricular aspect completely eliminated complex accessory pathway conduction, resulting in the disappearance of atrial double potentials.
