Key result
Radiofrequency catheter ablation successfully eliminated a concealed left posteroseptal accessory pathway within the neck of a coronary sinus diverticulum.
Case Report (n=1)
This case highlights the importance of performing coronary sinus venography before ablation of posteroseptal accessory pathways to identify anatomical anomalies such as a coronary sinus diverticulum.

May warrant coronary sinus venography before posteroseptal accessory pathway ablation; leaves open whether routine use improves outcomes.
Matsuo et al. (2000) conducted a case report in Concealed atrioventricular accessory pathway associated with a coronary sinus diverticulum (n=1). Radiofrequency catheter ablation was evaluated on Successful ablation of the pathway. Radiofrequency catheter ablation successfully eliminated a concealed left posteroseptal accessory pathway within the neck of a coronary sinus diverticulum.
