Radiofrequency ablation is effective in abolishing persistent supraventricular tachycardia caused by an iatrogenic atrioventricular bypass tract after a modified Fontan operation.
Sir,—Rosenthal et al recently documented the presence of an atrioventricular bypass tract after a modified Fontan operation in which the right atrial appendage was anastomosed to the right ventricular outflow tract.1Their patient developed persistent supraventricular tachycardia resulting from atrioventricular re-entry within the surgical right anastomosis, which was abolished by radiofrequency ablation. They also mentioned a previous report of ablation after the Fontan operation.2 Based on the evidence of these …

Granado et al. (1997) conducted a letter in Tricuspid atresia and supraventricular tachycardia after Fontan operation. Radiofrequency ablation was evaluated on Abolition of supraventricular tachycardia. Radiofrequency ablation successfully abolished persistent supraventricular tachycardia resulting from an iatrogenic atrioventricular bypass tract after a modified Fontan operation.
