Suivi des patients traités par conduits entre le ventricule droit et l'artère pulmonaire

Published in Archives des maladies du coeur et des vaisseaux - Pratique. 2000, vol. 93, no. 5, p. 527-32
Abstract Between 1981 and 1998, 77 right ventricle-pulmonary artery conduits were implanted in 67 patients (37 boys, 30 girls, average age 6.3 years; range: 3 months to 17 years). The diagnoses were transposition of the great arteries with ventricular septal defect and obstruction of the pulmonary outflow tract (N = 22), tetralogy of Fallot (N = 16), truncus arteriosus (N = 9), double outlet right ventricle with pulmonary stenosis or atresia (N = 8) and agenesis of the pulmonary valve with pulmonary stenosis (N = 2). The implanted conduits were homografts in 50 cases (43 aortic and 7 pulmonary), 11 valved Dacron grafts, 4 valved polystans grafts and 2 non-valved conduits. The average follow-up period was 3.6 years (range: 1 month to 17 years). Early death was observed in 8 patients (12%) and late death in 6 patients (9%). The 5, 10 and 15 year survival rates were 78.4%, 65.3%, and 65.3%, respectively. The conduits had to be replaced in 10 patients (15%). The non-replacement rate of all conduits at 5, 10 and 15 years was 81.4%; 40.7% and 40.7%, respectively. The causes of replacement were pure stenosis (54.5%), pure regurgitation (9%) and mixed stenosis and regurgitation (27.2%). These results are comparable to other published series showing a 15 year survival rate of 65% and a 59% reoperation rate at 15 years. Homografts have a slightly longer life compared with valved Dacron conduits but the difference is not statistically significant.
