Mapping and ablation of supraventricular tachycardia in pediatric and congenital heart disease patients

The past two decades have witnessed astounding advances in the efficacy and safety of catheter ablation techniques as definitive therapy of supraventricular tachycardia, with application to an ever widening spectrum of pediatric and congenital heart disease patients. This review covers both general considerations in pediatric ablation and technical pearls specific to a variety of ablation targets. Tools of ablation, indications for ablation, historical outcomes and unique considerations in children and complex congenital heart disease are addressed. This is followed by discussion of ablation of accessory pathways, AV node reentrant tachycardia, focal atrial tachycardia in structurally normal hearts and atrial tachycardia in congenital heart disease.
