Wolff-Parkinson-White syndrome case due to a coronary sinus accessory pathway in a patient with unique congenital coronary venous anomaly: a case report.

ABSTRACT:

Background

Catheter ablation for Wolff-Parkinson-White syndrome (WPW) has a failure rate of 1-5%, particularly when accessory pathways (APs) are located in challenging regions like the posteroseptal or left posterior areas. These cases may involve coronary sinus (CS) APs and anomalies in the coronary venous system, especially in those with a previous failed ablation procedure. Imaging of the coronary venous system obtained by cardiac computed tomography (CT) can help the procedural planning in the presence of challenging anatomy.

Case summary

We present the case of a 16-year-old male with WPW syndrome due to a posteroseptal AP, referred to our institution after two failed ablation procedures. Cardiac CT performed before the third attempt revealed CS drainage into the left at
