Successful transcatheter ablation of congenital junctional ectopic tachycardia in a ten-month-old infant using radiofrequency energy.

Congenital junctional tachycardia is a difficult-to-control rhythm in children which has a high mortality rate with current management. A 10-month-old child followed since birth with the diagnosis of congenital junctional ectopic tachycardia is reported. He failed treatment with multiple antiarrhythmic agents, and underwent an electrophysiology study. The junctional focus was successfully ablated using transcatheter radiofrequency energy. This technique may be safer than high voltage DC shock ablation, particularly in small children.
