Arrhythmias in children undergoing orthotopic heart transplantation.

Introduction: Heart transplantation (HT) is the only treatment option in children with heart failure secondary to cardiomyopathies and non-reparable congenital heart diseases.

Methods: We performed a retrospective clinical data review of all consecutive pediatric patients (aged 2-18 years) who underwent orthotopic HT for advanced heart failure at our institution between January 2007 and January 2023. Clinical, procedural, and follow-up data were collected and comprehensively analyzed.
