摘要
Congenital aortic arch anomalies occur most commonly in children. The disease can be classified into three types： ① obstructive congenital abnormalities, including coarctation of aorta （CoA） and interruption of aortic arch （IAA）; ② nonobstructive congenital abnormalities, including double aortic arch and others; ③ congenital shunt abnormalities, including different types of patent ductus arteriosus （PDA）. Management of patients with congenital aortic arch anomalies relies on imaging. Routine imaging modalities, such as conventional X-ray plain film and transthoracic echocardiography （TTE）, have been recently complemented by magnetic resonance imaging （MRI）.
