Objective Summarize and review on surgical repair of congenital heart disease in infants. Methods Between January 1988 and June 2003, seven hundred and eighty seven less than 6 months of age patients were operated. There were 109 cases of complete transposition of the great arteries(D-TGA), 51 total abnormal pulmonary venous connection(TAPVC), 16 pulmonary atresia with ventricular septal defect(VSD), 33 coarctation of aorta, 299 VSD with pulmonary hypertention, 44 tetralogy of Fallot, 23 double outlet right ventricle, 9 pulmonary atresia with intact ventricle septum, et al. The operative procedure was dependent on different disease. Results There were 77 patients died, the total mortality was 9.78%(77/787). Following improvement of surgical procedure, the mortality was decreased from 25% in 1988-1995 to 4.11% in 2003. In the D-TGA patients, there was one residual VSD who was repaired 3 months late, and two had mild pulmonary and aortic supravalve obstruction. They were still be followed up. Two patients with intracardiac type of TAPVC had venous return obstruction, one was died and another was re-operated 4 days later. In the VSD patients, there were 5 patients with residural VSD, but all of them did not need to repair. Conclusion The time of surgical repair is very important, especially for complex congenital heart disease. The best operative procedure will be lost, if the infants is repaired too late, the postoperative events and mortality will be increased.
