Key result
Point catheter ablation of re-entrant ventricular tachycardia was successful in a patient after surgical repair for double-outlet right ventricle, aided by intra-cardiac echocardiography.
Case Report (n=1)
Intra-cardiac echocardiography is useful for identifying the ventricular septal defect patch to guide point catheter ablation of ventricular tachycardia in patients with surgically repaired congenital heart disease.

May support intra-cardiac echocardiography guidance for ablation in repaired congenital heart disease; leaves open generalizability beyond single cases.
Catheter ablation of ventricular tachycardia is often difficult in patients after surgery for CHD. In patients with a ventricular septal defect patch, it is necessary to decide which ventricular side is appropriate for catheter ablation. In this article, we report a case of successful point catheter ablation of re-entrant ventricular tachycardia. Identification of the ventricular septal defect patch using intra-cardiac echocardiography was useful.

Izumi et al. (2017) conducted a case report in Macro-re-entrant ventricular tachycardia after surgical repair for double-outlet right ventricle (n=1). Point catheter ablation using intra-cardiac echocardiography was evaluated on Successful ablation. Point catheter ablation of re-entrant ventricular tachycardia was successful in a patient after surgical repair for double-outlet right ventricle, aided by intra-cardiac echocardiography.
