OBJECTIVETo report the experience of extracardiac conduit total cavopulmonary connection (ECTCPC) in surgical treatment of complex congenital heart diseases.

METHODSFrom 1998 to 2006, 68 patients underwent ECTCPC for complex congenital heart diseases. Among them, 45 had functional univentricle with transposition of the great artery (TGA) and pulmonary artery valve stenosis, 19 had tricuspid atresia with hypoplasia of right ventricle, 4 had Ebstein's anomaly with hypoplasia of right ventricle. Six had left superior vena cava, 18 had received Bidirectional Glenn operation; Fifty-seven cases were performed under cardiopulmonary bypass with general anesthesia and hypothermia, 11 cases were performed without cardiopulmonary bypass.

RESULTSThere were two death, the mortality was 2.9%. All patients were followed up from 1 to 8 years with no clinical symptoms and have been doing well. The arterial oxygen saturation was 90% - 96%, the cardiac function were in NYHA class I - II.

CONCLUSIONThe extra cardiac conduit TCPC is a simple procedure and superior to other type of Fontan procedure in most patients.
