Abstract

Abstract: We report the case of ventricular tachycardia (VT) ablation procedure in a patient with history of surgically repaired double‐outlet left ventricle. The electrophysiology procedure revealed a re‐entry pattern between the right‐ventricle to main‐pulmonary‐artery conduit and the tricuspid annulus. The re‐entrant mechanism was most likely promoted by a fibrous remodeling of this area, related to the surgical repair. This case is the first to describe a re‐entry mechanism between fixed anatomical barriers in a repaired right ventricle of a double‐outlet left ventricle. A pace mapping technique was used to highlight the VT isthmus.
