ABSTRACTTetralogy of Fallot is the most common cyanotic heart disease. Corrective intracardiac repair has been performed for › 40 years with excellent results. Nevertheless ventricular arrhythmias have consistently been reported, and sudden cardiac death is the most common cause of mortality late after repair. Programmed ventricular stimulation has been used in selected patients at many centers; however, attempts to clarify its predictive value have been limited by small patient number and relatively low event rates. The emergence of successful methods for both the prevention of arrhythmias, (including electrophysiological ablation and implantable defibrillators), has meant the identification of those at risk of even greater importance.
