Objective To summarize the clinical features and results of surgical treatment of complex congenital heart disease(CCHD) in infants, investigate the operative indications and improve the operative effect. Methods From November 1999 to June 2008, 323 infants with CCHD were operated in Wuhan Asia Heart Hospital. There were 202(62.5%) male and 121(37.5%) female aged from 4 days to 36 months. The average age was 18.4 months. The range of weight was 4-15 kg, and the average weight was 9.9 kg. There were 218 cases with tetralogy of fallot(TOF), 41 with double outlet right ventricle(DORV), 12 with total anomalous pulmonary venous drainage（TAPVD）, 8 with complete endocardial cushion defect（TECD）, 15 with coarctation of aorta（CoA）, 2 with aortapulmonary window（AP Window） associated with interrupted aortic arch(IAA) and patent ductus arteriosus (PDA), 2 with persistent truncus arteriosus (PTA), 9 with single ventricle（SV）, 2 with Ebstein’s anomaly, 10 with pulmonary atresia（PA）, 3 with transposition of great arteries（TGA）and 1 with corrected transposition of great arteries（cTGA）. Two hundred and ninetyseven patients underwent I stage correction, 26 underwent palliative operation. All the corrective operations were performed under hypothermic cardiopulmonary bypass（CPB）. Results The cardiopulmonary bypass(CPB) time and aortic cross clamping time were 89±34 min and 48±39 min, respectively. All the patients were followed up by telephone or mail. The follow-up time was 1-72 months. Eight patients（2.5%） died after operation, 7 of them died in the early period of operation(within 1 month). Two patients died of long operation time and CPBdependence, 3 died of ventilatordependence, 1 died of cardiac arrest caused by aspiration following multiple organ dysfunction syndrome（MODS）after resuscitation, and 1 died of continuous hypoxia and cardiac arrest after central shunt operation. There was 1 mediumterm death, which was caused by laryngitis complicated with pulmonary infection. There were 315 survivals（97.5%）. Ninetyfive cases had complications(29.4%), all discharged after symptomatic treatment. The [CM(159mm]improved cardiac function was in gradeⅠ-Ⅱ. The respiratory tract infection reduced and the weight increased significantly. Conclusion Early detection, early diagnosis and early surgical treatment are important for CCHD in infants and the surgical results are satisfactory. The surgical procedure should be chosen according to individual abnormality. Surgeons should pay attention not only to the operation indications and satisfactory correction of the abnormality, but also to the staging operation. 
