Atrioventricular node reentrant tachycardia ablation in a patient with congenitally corrected transposition of the great vessels using the CARTO mapping system.
We present a case of a 21-year-old female with congenitally corrected transposition of the great vessels and episodes of supraventricular tachycardia. We performed an electrophysiological study and successful ablation using an electro-anatomical mapping system. A single His bundle appeared to be located at the apex of the triangle of Koch and at electrophysiological study there was evidence of triple antegrade AV nodal pathways--slow, intermediate and fast, with two types of AV nodal re-entrant tachycardias. A series of radiofrequency ablations in the right posteroseptal area eliminated both slow and intermediate pathway conduction and cured the tachycardias.
