Posterior Coronary Vein as the Substrate for an Epicardial Accessory Pathway
Key result
CT imaging and electro-anatomic mapping link accessory pathway course to coronary sinus anatomy in WPW.
- n=1
Why the study?
Catheter ablation of Wolff-Parkinson-White syndrome fails in up to 5% of cases, with coronary sinus abnormalities linked to posteroseptal and left posterior accessory pathways.
Population
41-year-old patient with WPW syndrome after three unsuccessful ablations

Implication
CS-LV connections may underlie refractory posteroseptal AP; single case leaves open whether targeted mapping improves outcomes.

Relationship between accessory pathway electrical course and coronary sinus posterior branchsurrogate
CT imaging and electro-anatomic mapping can identify the relationship between accessory pathway electrical course and the coronary sinus posterior branch in complex WPW cases, supporting the presence of epicardial connections.
Cite This Study
Cipoletta et al. (2013) conducted a case report in Wolff-Parkinson-White syndrome (n=1). CT imaging and electro-anatomic mapping was evaluated on Relationship between accessory pathway electrical course and coronary sinus posterior branch. CT imaging and electro-anatomic mapping in a patient with WPW syndrome demonstrated a relationship between the accessory pathway electrical course and the coronary sinus posterior branch.
