Radiofrequency ablation at the coronary sinus os successfully treated a rare case of permanent junctional reciprocating tachycardia with overt anterograde ventricular preexcitation.
The substrate of the permanent form of junctional reciprocating tachycardia is an accessory pathway with no spontaneous anterograde conduction, usually located in the posteroseptal area. We report a case of this type of tachycardia with overt anterograde ventricular preexcitation. Electrophysiologic study confirmed that tachycardia was due to an accessory pathway with long retrograde conduction time; electrophysiologic findings suggested longitudinal dissociation of the accessory pathway. Radiofrequency application at the coronary sinus os resulted in disappearance of preexcitation and cure of the tachycardia.

Arribas et al. (1995) conducted a case report in Wolff-Parkinson-White Syndrome presenting as the permanent form of junctional reciprocating tachycardia (n=1). Radiofrequency application at the coronary sinus os was evaluated on Disappearance of preexcitation and cure of the tachycardia. Radiofrequency application at the coronary sinus os resulted in the disappearance of preexcitation and cure of the tachycardia in a patient with Wolff-Parkinson-White syndrome.
