RESUMO
Objective To evaluate roles of color doppler echocardiography(CDE)and angiocardiography(ANGI)in diagnosis of children's combined with congenital heart diseases(CHD).Methods From Jan.2006 to Jun.2008,31 children with combined with CHD underwent not only CDE but also ANGI.Of those,18 cases were subjected to surgical operation.Main diagnosis and concomitant cardiovascular malformations derived from CDE and ANGI,operative findings as well,were compared.Results In 18 cases undergoing surgery,diagnosis of 15(83.33%)cases from CDE and 17(94.44%)cases from ANGI were in line with the operative findings.Of intracardiac malformations,diffe-rences between CDE and ANGI were:CDE diagnosed 1 case with pulmonary atresia /ventricular septal defect(PA/VSD)as persistent truncus arteriosus(PTA),2 cases with tetralogy of Fallot(TOF)as PA/VSD by mistake,and 1 case with partial anomalous pulmonary venous connection(PAPVC)was suspected by CDE but missed by ANGI,all above mentioned confirmed by sugery;except main diagnosis,CDE missed atrial septal defect(ASD),anomalous origin of right coronary artery and single left coronary for 1 case,respectively.In diagnosing extracardiac abnormal structures:1 case of interrupted aortic arch(IAA)was suspected by CDE but diagnosed and classified by ANGI;for double aortic arch(DAA),pulmonary arteriovenous fistula(PAVF),patent ductus arteriosus(PDA)and absence of right pulmonary artery,1 case of each was missed by CDE;furthermore PDA reported by CDE but not found by ANGI in 4 cases with PA/VSD.Conclusions The diagnostic difference between CDE and ANGI mainly lies in extracardiac malformations including coronary arteries.In diagnosing combined CHD,combination of CDE and ANGI can improve accurate rate.J Appl Clin Pediatr,2009,24(1):44-45
