Ablation of atrioventricular nodal reentrant tachycardia in tricuspid atresia.
A 31-year-old woman with tricuspid atresia and a palliative Waterston shunt presented with intractable poorly tolerated supraventricular tachycardia. Electrophysiologic evaluation was consistent with AV nodal reentrant tachycardia. The fast pathway region was mapped electroanatomically during tachycardia and with constant rate ventricular pacing. Successful radiofrequency ablation was achieved by placement of lesions in an area adjacent and inferior to the His-bundle electrogram on the left side of the septum.
