Radiofrequency ablation successfully eliminated an accessory pathway located at the blind end of the coronary sinus in a patient with Wolff-Parkinson-White syndrome and anomalous coronary veins.
Case Report (n=1)
This case demonstrates successful ablation of an accessory pathway associated with anomalous coronary veins, suggesting a potential embryologic link.
We report a case of Wolff-Parkinson-White syndrome coexistent with atresia of the coronary sinus (CS) ostium and persistence of the left superior vena cava. The accessory pathway was located at the blind end of the CS, which was bumped with mechanical loss of preexcitation during mapping by a catheter from within the CS. The accessory pathway was successfully ablated with radiofrequency energy applied to this site from the right atrium. This unique combination of anatomically matched anomalies may be important in suggesting a potential embryologic link between the accessory pathway and the coronary vein.
Takatsuki et al. (2001) conducted a case report in Wolff-Parkinson-White syndrome with atresia of the coronary sinus ostium and persistence of the left superior vena cava (n=1). Radiofrequency ablation was evaluated on Successful ablation of the accessory pathway. Radiofrequency ablation successfully eliminated an accessory pathway located at the blind end of the coronary sinus in a patient with Wolff-Parkinson-White syndrome and anomalous coronary veins.
