Why the study?
The ECG characteristics and outcomes of catheter ablation for ventricular arrhythmias originating from the moderator band in children were not well investigated.
What are the electrocardiographic characteristics and outcomes of catheter ablation for ventricular arrhythmias originating from the moderator band in children?
What are the electrocardiographic characteristics and outcomes of catheter ablation for ventricular arrhythmias originating from the moderator band in children?
Catheter ablation using 3D electroanatomic mapping is safe and effective for treating moderator band ventricular arrhythmias in children, which present with distinct ECG characteristics including narrower QRS widths compared to tricuspid annulus origins.

May support ablation feasibility for pediatric MB VAs; leaves open need for larger prospective validation.
