Abstract：Objective To assess the diagnostic value of aortopulmonary septal defect (APSD) by Doppler echocardiography, and to analyze the misdiagnosis reasons to improve the correct rate of diagnosis in the future. Methods Doppler echocardiography was performed and this imaging was compared with operative or CT findings in 60 children with APSD. Results APSD was characterized by the presence of the"T"artifact and bidirection shunt at the margins of APSD,and pulmonary artery hypertension. The associated malformations included anomalous origin of right pulmonary artery from the ascending aorta (16 cases) ,interrupted aortic arch / coarctation of the aorta (13 cases) ,atrial septal defect / patent foramen ovale (9 cases) ,ventricular septal defect (9 cases) ,patent ductus arteriosus (7 cases) ,and pulmonary atresia with ventricular septal defect (1 case). TypeⅠ included 15 cases,typeⅡ 42 cases,and type Ⅲ 3 cases. 55 cases (91. 7％) were diagnosed correctly,5 cases (8. 3％) were misdiagnosed. In misdiagnosed cases,3 cases were missed diagnosis,2 cases were misdiagnosed. Conclusion APSD could be diagnosed accurately by Doppler echocardiography.
