%X Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart defect, and its surgical outcomes had been dramatically improved due to modern surgical and medical advances. The majority of post-repaired patients survive and reach adulthood, although some patients are at risk of several life-threatening complications, such as arrhythmia and sudden cardiac death (SCD) (1,2). Numerous reports have identified risk factors for ventricular tachyarrhythmia, including QRS duration, change rate of QRS duration, QTc duration, delay in corrective surgery, number of previous cardiac surgery, presence of ventriculotomy, trans-annular patch (TAP) repair, and left ventricular diastolic dysfunction (3-7). Those risk factors probably differ between institutions and countries, since the age at corrective surgery after palliative operation and operative procedure (incidence of TAP repair and size of the right ventriculotomy) might differ between them. The purpose of this study was to evaluate the long-term outcomes of total repair of TOF and to identify risk factors for ventricular tachyarrhythmia and SCD
