Key result
Radiofrequency application within the posterior coronary sinus achieved a change of activation pattern, indicating an accessory pathway between the coronary sinus musculature and the left ventricle.

Rare CS-LV accessory pathway ablated from posterior CS; extends mapping options but leaves broader applicability hypothesis-generating.
Case Report (n=1)
This case demonstrates an accessory pathway connecting the coronary sinus musculature and the left ventricle, successfully treated with radiofrequency ablation.
Takenaka et al. (2019) conducted a case report in Long R-P' tachycardia with an accessory pathway (n=1). Radiofrequency catheter ablation was evaluated on Change of activation pattern and conduction block. Radiofrequency application within the posterior coronary sinus achieved a change of activation pattern, indicating an accessory pathway between the coronary sinus musculature and the left ventricle.
