Objective:Analysis of complex congenital heart disease of children and the incidence of coronary abnormalities to explore the21(4):453-457. diagnostic value of coronary angiography.Methods:Angiocardio graphy cardiac catheterization of 229 children in Heart Center of Children’s Hospital Chongqing Medical University from January 2006 to June 2009

the results were retrospectively analyzed

including the types and proportion of congenital heart diseases

incidences of coronary artery abnormalities

incidences of abnormal coronary artery crossing right ventricular outflow tract and prognosis.Results:Altogether

27(11.8%)cases of children with Congenital Coronary Artery Anomalies were detected.Highest incidenc(e6.55%)is L-coronary artery

which occupy 55.56% of Coronary Artery Anomalies.16(6.99%) cases of abnormal coronary artery crossing the right ventricular outflow tract

which including 7 cases of TOF

3 cases of DORV

3 cases of PA/VSD

1 case of TGA

1 case of CAVC and 1 case of SV/TGA.1 patient died of angiocardiography among the 27 cases of complicating coronary artery malformation

accounting for 3.7%in the total number of the angiography of complex congenital heart disease complicating coronary artery malformation

accounting for 0.44%in the total number of complex congenital heart disease.3 cases died after surgery

accounting for 16.7% of surgery.Conclusion:The incidence of coronary artery abnormalities in complex congenital heart disease in children is higher than the normal population;coronary angiography is an important means of final diagnosis coronary artery congenital variation.
