Low energy catheter ablation of a posteroseptal accessory pathway associated with a diverticulum of the coronary sinus.
A 23-year-old man was resuscitated from ventricular fibrillation and subsequently shown to have the Wolff-Parkinson-White syndrome. Electrophysiological study demonstrated a posteroseptal accessory pathway, and coronary sinus angiography demonstrated that this was associated with a diverticulum of the coronary sinus. Catheter ablation was performed using a new low energy system. Five shocks were delivered within the coronary sinus diverticulum, with a cumulative energy of 39 joules (J). Accessory pathway conduction was blocked successfully, and there were no complications.
