Abstract
Introduction: Among adult patients with previous surgical correction for Tetralogy of Fallot (ToF) or other repaired Congenital Heart Disease (rCHD) involving the Righ Ventricular (RV) outflow, ventricular arrhythmias (VA) and sudden cardiac death (SCD) represent a late complication. The impaired hemodynamics that lead to RV dilatation and overload could also modify its electrical properties. 3D Electroanatomic Voltage Mapping (EVM) of the RV could confirm the presence of myocardial electrical abnormalities, allowing to better identify patients at risk of life-threatening arrhythmias.
