90% are found in the distal isthmus of the left subclavian artery

Simple type

Complex type combined with other malformations

Child with heart failure in 2 months

Adults have no obvious symptoms

Aortic node depression

Dilated intercostal artery compression

Most common methods of diagnosis

Visually display the entire aorta, including the location, scope, and degree of coarctation.

Whether combined with PDA and whether aortic arch hypoplasia

Show collateral circulation

Blood flow sequence measurement of flow velocity and pressure difference

Cine sequence shows secondary changes in the heart

There is no direct communication between the ascending aorta and the descending aorta

Type A

Type B

Type C

Often combined with the triad of PDA, ventricular septal defect, and aortic arch disconnection

Aortic node depression

Dilated intercostal artery compression

The most commonly used diagnostic methods show the whole picture and clarify the separation and classification

The location of aortic disconnection and the relationship between the brachiocephalic artery and the brachiocephalic artery are classified

Whether combined with PDA and ventricular septal defect
