Ventricular Tachycardia Rotating a Scar of a Total Right Ventricular Exclusion.

Abstract

We describe a 15-year-old postoperative girl who underwent surgical 3-dimensional mapping and ablation of hemodynamically unstable ventricular tachycardia (VT) with an on-pump beating heart surgical technique. She had previously received a tricuspid valve closure, entire right ventricular free wall resection, and finally Fontan operation with an extracardiac conduit to treat a severe Ebstein's anomaly. Activation mapping revealed a VT rotating around a large right ventricular free wall incisional scar with a narrow conduction channel between the scar and a tricuspid annulus (TA). A linear radiofrequency ablation connecting the scar and the TA terminated the VT.
