Successful catheter ablation for ventricular tachycardia after cone procedure in Ebstein anomaly

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...
