Extracardiac Conduit Repair (ECCR) is conventionally selected for the Tetralogy of Fallot (TOF) with unusual coronary artery distribution. However, in recent years conduit obstruction has been an important factor. Recently, we select the Right Ventricle Outflow Tract Reconstruction (RVOTR) using direct anastomosis between PA and RV as much as possible. In this paper, RVTOR was compared with ECCR. RVOT stenosis was relieved sufficiently and the ventricular function was well maintained after both surgical methods. We concluded that RVOTR should be selected instead of the ECCR because of the conduit obstruction.
