First report of image integration of cine-angiography with 3D electro-anatomical mapping of the right ventricle in postoperative tetralogy of Fallot.

Ventricular tachycardia and, more rarely, sudden cardiac death are potential complications affecting the long-term outcome after Tetralogy of Fallot (ToF) repair. Intraventricular septal scar, fibro-fatty substitution around infundibular resection and patchy myocardial fibrosis may provide anatomical substrates of abnormal depolarization and repolarization causing reentrant ventricular arrhythmias. Recently, three-dimensional electro-anatomical mapping (3D EAM) has allowed to investigate the electro-anatomical status of the right ventricle.
