We detail the simultaneous surgical treatment of Ebstein's anomaly combined with Wolff-Parkinson-White
syndrome in a patient who presented with multiple accessory conduction pathways. The
extensively deformed tricuspid valve was replaced by a Hancock xenograft and the atrialized
ventricle was plicated. Surgery was performed under the beating heart condition and
this made possible electrical mapping which facilitated the localization of both accessory
pathways. By the method presented here, all existing accessory pathways can be pinpointed
during open heart surgery and the time of their interruption can be established.
Two and a half years after surgery, chest X-ray revealed marked reduction of the cardiothoracic
ratio and the patient experienced no postoperative tachycardia episodes.
