Epicardial Intraoperative Three-Dimensional Mapping of Wolff-Parkinson-White Syndrome in a Child With Ebstein’s Anomaly

This report shows adaptation of a three-dimensional electroanatomic mapping system for intraoperative use in a small patient with Ebstein’s anomaly who was undergoing a cone procedure and a bidirectional Glenn procedure. Use of this technique gave clear identification of the epicardial insertion points of two accessory pathways causing Wolff-Parkinson-White syndrome and resistant episodes of supraventricular tachycardia. Successful three-dimensional mapping and cryoablation were performed with a short procedure time and no complications. The patient remains without preexcitation or arrhythmia 6 months postoperatively.
