Key result
A new right lateral accessory pathway appeared six months after the Cone procedure in a 27-year-old male with Ebstein's anomaly, which was successfully abolished by a second catheter ablation.
Why the study?
Acquired Wolff-Parkinson-White syndrome can occur after congenital heart disease surgery.
Case Report (n=1)
The appearance of a new accessory pathway after the Cone procedure for Ebstein's anomaly is a rare finding that should raise suspicion of an acquired connection.
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.

Nguyen et al. (2023) conducted a case report in Ebstein's anomaly and manifest WPW syndrome (n=1). Cone procedure and catheter ablation was evaluated on Appearance of a new accessory pathway. A new right lateral accessory pathway appeared six months after the Cone procedure in a 27-year-old male with Ebstein's anomaly, which was successfully abolished by a second catheter ablation.
