Key result
Catheter ablation was successfully performed for ventricular tachycardia after a cone procedure in Ebstein anomaly.
Why the study?
Despite the good outcomes of cone reconstruction in Ebstein anomaly, arrhythmic complications can occur after the procedure.
Case Report
Catheter ablation may be a successful treatment for ventricular tachycardia occurring after cone reconstruction in Ebstein anomaly.

Arrhythmic risk persists after cone reconstruction in Ebstein anomaly; leaves open optimal ablation timing and targets in larger cohorts.
Ebstein anomaly (EA) is a rare congenital heart disorder characterized by delaminated tricuspid valve (TV). This condition serves as an arrhythmic substrate contributing to atrial and/or ventricular arrhythmia and is notably associated with a high incidence of arrhythmias.1,2 The cone reconstruction (CR) approach, which was first described by da Silva3 in 2007, has advanced with time and is widely applied to patients with EA.4 Despite the good outcomes of CR,5,6 arrhythmic complications can occur after the procedure.
