Why the study?
Does catheter ablation using a low energy system successfully block accessory pathway conduction in a patient with Wolff-Parkinson-White syndrome and a coronary sinus diverticulum?
Does catheter ablation using a low energy system successfully block accessory pathway conduction in a patient with Wolff-Parkinson-White syndrome and a coronary sinus diverticulum?
Low energy catheter ablation successfully blocked accessory pathway conduction without complications in a patient with WPW syndrome and a coronary sinus diverticulum.
May support low-energy ablation in WPW with CS diverticulum; hypothesis-generating and should not yet change practice.
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.
