This case report describes a patient with a sustained monomorphic VT after surgical repair of a tetralogy of Fallot (TOF). In combination with the three‐dimensional electroanatomic mapping system, CARTO, and conventional mapping techniques the VT was identified as a macro‐reentrant tachycardia circling around the border between pulmonary graft and right ventricular outflow tract (RVOT). A y‐shaped ablation line crossing this zone was created. The VT terminated during RF application and was not inducible again. This case underlines the use of a combined conventional and three‐dimensional electroanatomic mapping technique can be helpful for catheter ablation of ventricular arrhythmias in TOF patients.
