Simultaneous Epicardial and Endocardial Mapping of a Left‐Sided Posteroseptal Accessory Pathway Associated with a Large Coronary Sinus Diverticulum: Successful Ablation by Transection of the Diverticulum's Neck
Key result
Intravascular linear diverticular neck lesions enable successful accessory pathway ablation after failed epicardial attempts.
- n=1
Why the study?
Challenges in ablating left-sided posteroseptal accessory pathways associated with large coronary sinus diverticula after multiple unsuccessful procedures require alternative approaches.
Does transection of the diverticulum's neck allow successful ablation in a patient with a left-sided posteroseptal accessory pathway and a large coronary sinus diverticulum?

Implication
May be considered in select refractory left posteroseptal APs with CS diverticulum; leaves open generalizability.

Structured PICO
Does transection of the diverticulum's neck allow successful ablation in a patient with a left-sided posteroseptal accessory pathway and a large coronary sinus diverticulum?
P
Population
1 patient with a left-sided posteroseptal accessory pathway associated with a large coronary sinus diverticulum who had three previous unsuccessful ablations.
I
Intervention
Intravascular linear lesions transecting the neck of the large coronary sinus diverticulum using a pericardial catheter as a target for radiofrequency catheter ablation
O
Outcome
Successful radiofrequency catheter ablation of the accessory pathway
Intravascular linear lesions transecting the neck of a coronary sinus diverticulum using a pericardial catheter as a target can enable successful ablation of an accessory pathway when epicardial energy delivery is not possible.
Cite This Study
Saad et al. (2002) conducted a case report in Left-sided posteroseptal accessory pathway associated with a large coronary sinus diverticulum (n=1). Intravascular linear lesions transecting the neck of the large coronary sinus diverticulum was evaluated on Successful radiofrequency catheter ablation of the accessory pathway. Intravascular linear lesions transecting the neck of a large coronary sinus diverticulum allowed successful radiofrequency catheter ablation of an accessory pathway after epicardial ablation failed.
