A challenging catheter ablation of anteroseptal manifest accessory pathway from non-coronary aortic cusp in a paediatric patient

Twelve-lead ECG of a child with Wolff–Parkinson–White syndrome and systolic dysfunction was consistent with the anteroseptal accessory pathway. The earliest atrial activation during electrophysiological study was found between the right anteroseptal region near the HIS. Multiple femoral tract right-...

Description
Summary:Twelve-lead ECG of a child with Wolff–Parkinson–White syndrome and systolic dysfunction was consistent with the anteroseptal accessory pathway. The earliest atrial activation during electrophysiological study was found between the right anteroseptal region near the HIS. Multiple femoral tract right-sided cryotest lesions followed by radiofrequency catheter irrigated through the jugular vein route were unsuccessful. Then, non-coronary aortic cusp mapping and cryoablation were successfully performed with a retroartic approach.
