Abstract:
In patients with Ebstein's anomaly, the localization of accessory pathways may be impeded by abnormal local electrograms recorded along the atrialized right ventricle and by the presence of multiple accessory pathways. We report a case of 50-year-old man diagnosed with Ebstein's anomaly with Wolff-Parkinson-White syndrome who presented with recurrent palpitations. He was referred to our institution for radiofrequency catheter ablation of paroxysmal supraventricular tachycardia. Transthoracic echocardiography revealed the tricuspid valve displaced into the right ventricle, consistent with Ebstein's anomaly. The electrophysiology study showed a right posterolateral accessory pathway. The optimal ablation site was located not in the atrioventricular line of the atrialized ventricular portion, but in the original atrioventricular line.
