Repair of congenital heart disease in 1831 infants under the age of six months

Objective To review our experience of surgical repair of congenital heart disease in infants under 6 months of age.Methods Between January 2000 and December 2006.one thousand eight hundred and thirty one infants were operated on.There were 204 complete transposition of the great arteries(TGA),106 total abnormal pulmonary venous connection(TAPVC),119 Tetralogy of Fallot,69 double outlet right ventricle,55 Complete atriventricular defect,46 coarctation of aorta with ventricular septal defect,36 pulmonary atrisia with ventricular septal defect,31 pulmonary atrisia with intact ventricle septat,24 Interrupted aortic arch,22 Taussig-Bing,453 ventricular septal defect with pulmonary hypertension.Results There were 98 operative deaths with total mortality rate of 5.4 %.With improvemenr of surgical procedures,the mortality decreased from 8.23% in 2000 to 4.9 % in 2006.In the TGA group,there were one residual VSD,5 pulmonary super valve obstruction,2 aortic super valve obstruction and one with aortic sub-valvular obstruction,4 patients were re-operated on.Four patients with intracardiac type of TAPVC had venous return obstruction.two patients died and another two were re-operated on.In the VSD group,there were 5 patients with residual VSD at early stage,which required no repair.Conclusions The timing of surgical repair is very important,especially for complex congenital heart disease.The best operative procedure will be lost,if the infants is repaired late when the operative morbidity and mortality are increased.
