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.
