Introduction :
Congenital heart diseases involving the right ventricular outflow tract (RVOT) such as tetralogy of Fallot (TOF), pulmonary atresia or truncus arteriosus are frequently observed in cardiopediatric pathology and require most of the time a surgical correction during childhood. Different techniques have raised to treat an obstruction of the RVOT: pulmonary enlargement with a patch of pericardium and insertion of a right ventricular-pulmonary artery (RV-PA) conduit for reconstruction of the RVOT. Pulmonary homograft (PH) implantation has become over the past decades the conduit of choice for surgical treatment of a RVOT obstruction [1]. Small size of PH implanted [2,3], blood group incompatibility [4,5], young age of the recipient [6] are reported as risk factors of PH failure. Nonetheless, such results have been described with series of PH implanted with wide range of homograft sizes, according to the body surface index of the recipients who were most of the time newborns and children. Results of PH implantation for RVOT reconstruction are less known in grown-up congenital heart disease (GUCH) patients, especially those who underwent a primary surgical correction of congenital heart disease during childhood. The aim of this study was to evaluate the long term results of the implantation of homogeneous sizes of PH in a grown-up population of patients with congenital heart disease.
