Key result
Moderator band VT linked to reversible cardiomyopathy in a rare pediatric case.
Why the study?
Idiopathic VT originating from the moderator band is well reported in adults but is not well reported in the pediatric population.
Case Report (n=1)
Highlights a rare case of idiopathic ventricular tachycardia originating from the moderator band in a pediatric patient leading to reversible cardiomyopathy.
Moderator band VT in children may be underrecognized; extends sparse pediatric reports but leaves optimal management open.
Idiopathic ventricular tachycardia (VT) in children with a structurally normal heart most commonly arises from the ventricular outflow tracts and is typically benign.(1) In contrast, idiopathic non-outflow tract VT is uncommon.(2) Such idiopathic VT originating from the moderator band although well reported in adults is not well reported in the pediatric population.(3) The moderator band is a muscular structure in the right ventricular (RV) body connecting the interventricular septum to the RV free wall.

Jayswal et al. (2026) conducted a case report in Moderator Band Ventricular Tachycardia (n=1). Moderator band ventricular tachycardia was evaluated. Moderator band ventricular tachycardia caused reversible cardiomyopathy in a child, highlighting an uncommon presentation of non-outflow tract VT in the pediatric population.
