Abstract

Introduction: Acquired Wolff–Parkinson–White (WPW) syndrome can occur after congenital heart disease (CHD) surgery. Methods and Results: A 27-year-old male with Ebstein's anomaly and manifest WPW syndrome received catheter ablation twice. The first electrophysiology study (EPS) induced orthodromic atrioventricular reentrant tachycardia and successfully eliminated the posteroseptal accessory pathway (AP). Six months after the Cone procedure, the patient suffered from palpitation. The second EPS was performed and abolished the right lateral AP. Conclusion: The appearance of a new AP after the reconstruction of CHD is a rare finding and should raise suspicion of an acquired AP connection.
