ition of great arteries (CCTGA) by color doppler echocardiography (CDE).　Methods　Forty patients with CCTGA established by surgery or CT or angiocardiography were analyzed retrospectively.  Results　28 cases were S.L.L, all of these were levocardia，12 cases were I.D.D，8 cases were mirror image dextrocardia and the other were levocardia. Tricuspid valve anomaly was the most common accompanied malformations, ventricular septal defect(VSD) was the second and the left ventricular outflow tract obstruction (LVOTO) was third. 25 cases with intact ventricular septum had tricuspid valve anomaly, none of these had LVOTO, most of 15 cases with VSD had  LVOTO, an only 2 cases had tricuspid valve anomaly.　Conclusion S.L.L was the most common type in CCTGA, tricuspid valve anomaly was the most common accompanied malformations, VSD was the second and LVOTO was the third. Tricuspid valve anomaly is always accompanied by CCTGA with intact ventricular septum, left ventricular outflow tract obstruction was always accompanied by CCTGA with ventricular septal defect.
