Abstract

The management of arrhythmias in pediatric patients with corrected congenital heart disease (CHD) presents a challenge due to the interplay between scar-related anatomical substrates and autonomic dysfunction (1, 2). While iatrogenic substrate modification can lead to macro-reentrant tachycardias, such as atrial flutter (AFl), the development of sinus node dysfunction (SND) creates a difficult therapeutic dilemma regarding the need for permanent pacing (1). Post-surgical AFl typically involves circuits dependent on the cavotricuspid isthmus (CTI) or atypical circuits related to surgical incision lines.
