Key result
Combined catheter and surgical ablation successfully treats refractory VT in isolated RV hypoplasia.
Why the study?
Surgical ablation is an established treatment for tachyarrhythmias in congenital heart disease but is typically reserved for cases refractory to catheter ablation or medical therapy.
Case Report (n=1)
Combined catheter and surgical ablation was shown to be a successful and viable treatment for refractory, life-threatening ventricular tachycardia in a patient with complex congenital heart disease.
May support surgical ablation for refractory VT post-isolated RV hypoplasia repair when catheter ablation fails; leaves open generalizability pending larger studies.
Surgical ablation for tachyarrhythmias in patients with congenital heart disease has been on the rise in recent years and is now established as a viable treatment option, including for atrial flutter (AFL) and atrial fibrillation.1 However, given the risks of sinus node dysfunction and atrioventricular block, surgical ablation is typically reserved for cases where catheter ablation or medical therapy has been ineffective. Here, we report a case of refractory ventricular tachycardia (VT) following one-and-a-half ventricle repair for isolated right ventricle hypoplasia (IRVH), which was successfully treated with surgical ablation, resulting in a favorable clinical outcome.

Homma et al. (2026) conducted a case report in Refractory ventricular tachycardia in isolated right ventricle hypoplasia (n=1). Combined catheter and surgical ablation was evaluated on Clinical outcome. Combined catheter and surgical ablation successfully treated refractory ventricular tachycardia in a patient with isolated right ventricle hypoplasia, resulting in a favorable clinical outcome.
