title: Right ventricle to pulmonary artery connections.
abstract: From March 1988 through June 1995, 80 patients underwent repair for right ventricle (RV) to pulmonary artery (PA) discontinuity. Of these, 30 patients received homograft conduits, while the remaining 50 underwent repair without the use of a homograft. Handmade pericardial valved vascutek conduits (n = 18), non-valved vascutek tubes (n = 13) and non-conduit procedures like the rev operation (n = 12) and extended pericardial gusset (n = 5) were mainly used. The indications for repair for RV-PA discontinuity included ventricular septal defect with pulmonary atresia (VSD PA) (n = 36), truncus arteriosus (n = 18), ventricular septal defect with pulmonary and major aorto-pulmonary collaterals (VSD PA MAPCA) with staged repair (n = 5), congenitally corrected transposition of the great arteries with ventricular septal defect and pulmonic stenosis (CCTGA VSD PS) (n = 5) and double outlet left ventricle with ventricular septal defect and pulmonic stenosis (DOLV VSD PS) (n = 5). The choice of the procedure was governed by various factors, including type of cardiac defect, pulmonary artery pressure and morphology, previous operation, socio-economic constraints and availability of appropriate sized homografts. Non-circuit operations may prevent future reoperations in these patients.
