TRANSCATHETER RADIOFREQUENCY ABLATION FOR CONGENITAL JUNCTIONAL ECTOPIC TACHYCARDIA IN INFANCY

Congenital junctional ectopic tachycardia (JET) is a difficult to trea t arrhythmia with a variably poor response to pharmacologic interventi on. We report on the successful treatment of a 17-day-old infant with JET via transcatheter radiofrequency ablation of the arrhythmogenic fo cus resulting in resolution of the tachycardia and maintenance of norm al atrioventricular nodal function. Transcatheter radiofrequency ablat ion techniques should be considered in infants with life-threatening a rrhythmia recalcitrant to standard forms of drug therapy.
