Interruption of the aortic arch
Macroscopic appearance
- the aorta is totally disconnected:
- type A: interruption distal to the left subclavian artery
- type B: interruption distal to the left common carotid, the most common type
- type C: interruption distal to the innominate artery
- rare defect, almost always associated with ventricular septal defect or some other defect
- Di George syndrome is found in 70% of patients with interruption of the aortic arch,
this marked association is true for the type B
