Abstract：Objective:To explore the value of doppler ultrasonography in differential diagnosis of congenital heart disease in children.Methods:All sity-seven suspected children with congenital heart disease admitted to the hospital from May 2021 to December 2022 were selected to undergo doppler ultrasound and angiocardiography.According to the results of angiocardiography,the value of Doppler ultrasound in diagnosis and type differentiation of congenital heart disease in children was analyzed.Results:In 67 suspected children with congenital heart disease,56 cases(83.58%)were confirmed by angiography,including 6 cases of patent arterial duct,9 cases of tetralogy of fallot,23 cases of ven-tricular septal defect,3 cases of endocardial pad defect,7 cases of atrioventricular septal defect and 8 cases of subtricus-pid valve malformation.According to the results of angiocardiography,the sensitivity,specificity and accuracy of doppler ultrasound in the diagnosis of congenital heart disease in children were 100.00%,81.82%and 97.01%,which were in good agreement with the results of angiocardiography(Kappa value=0.883).According to the results of CVD exami-nation,the accuracy of doppler ultrasound in distinguishing types of congenital heart disease in children was 92.86%,and it was in good agreement with the results of CVD examination(Kappa value=0.906).Conclusion:Doppler ultra-sound has high diagnostic value in children with congenital heart disease,and can effectively identify the types of con-genital heart disease in children.
