Catheter cryoablation for pediatric arrhythmias

Kathryn K. Collins, George F. Van Hare

Research output: Chapter in Book/Report/Conference proceedingChapter


In pediatric patients with normal heart structure, the most commonly encountered tachyarrhythmias are accessory pathway-mediated tachycardia and atrioventricular nodal reentrant tachycardia (AVNRT). This chapter reviews catheter cryoablation techniques, clinical outcomes, and current utilization of cryoablation for tachyarrhythmias in a pediatric population. It talks about the effects of ablation on the immature myocardium, and also presents the outcomes of cryoablation for AVNRT in a pediatric population. The potential benefit of cryoablation in congenital heart disease would be for those patients in whom the normal conduction system is displaced from its usual anatomic location.
