Although radiofrequency ablation is highly successful in patients with the Wolff‐Parkinson‐White syndrome, certain patbways remain refractory to ablation. In particular, subepicardial pathways often fail ablation via an endocardial approach. In adult patients, left‐sided subepicardial pathways bave been treated successfully using energy delivery within the coronary sinus. To document the safety and efficacy of this approach in children, we present the case of a 6‐year‐old boy who underwent radiofrequency ablation of a posteroseptal pathway via energy delivery within tbe middle cardiac vein. Follow‐up study showed no evidence of recurrence or gross coronary vascular injury.
