Objective To summarize the experience of right ventricular outflow tract reconstruction with self-made single-valve conduit for the treatment of complex congenital heart disease, and to explore the key points of operation, and to evaluate the short-term and medium-term results of the treatment.Methods We retrospectively analyzed the clinical data of 65 patients with complex congenital heart disease treated by self-made single-valve conduit from January 2006 to June 2018. There were 42 males and 23 females aged 5-23 (9.9±4.2) years with weight 15-65 (26.2±9.9) kg. There were 19 patients with single valve artificial blood vessel (an artificial vascular group), and 46 patients with single valve bovine pericardium tube (a bovine pericardial tube group). There were 48 patients of ventricular septal defect (VSD) with pulmonary atresia (PA), 10 patients of corrective transposition of great artery with pulmonary artery stenosis, 5 patients of tetralogy of Fallot with single coronary artery malformation, 2 patients of double outlet of right ventricle with pulmonary artery stenosis and single coronary artery malformation.Results Two patients died early after operation, both of them were VSD/PA patients who underwent radical treatment of extravascular prosthesis. The right ventricular outflow tract pressure difference was 13-37 (25.2±4.9) mm Hg in the artificial vascular group and 5-23 (10.5±3.3) mm Hg in the bovine pericardial tube group. No obvious reflux was found at discharge. The patients were followed up for 8 months to 13 years. One patient was lost. During the follow-up period, there were 5 patients of moderate tricuspid regurgitation, 32 patients of moderate intraductal regurgitation, 7 patients of severe right ventricular outflow tract obstruction, 11 patients of moderate obstruction and 25 patients of mild obstruction. There was no late death. Heart function classification of all patients was in New York Heart Association classⅠtoⅡ.Conclusion The self-made single-valve conduit used to reconstruct right ventricular outflow tract shows good clinical effect. Using bovine pericardium tube has less pressure difference of outflow tract in comparison with artificial blood vessel. Bovine pericardium tube is more recommended for young and low weight patients.
