Diagnosis: Coarctation of the Aorta
Findings: Focal narrowing of the descending aorta distal to the great vessels as visualized on sagittal view of the aorta on CTA.
Key Points: CTA and MRA can enabled clear cross sectional visualization of the aortic coarctation. One can also look for collateralization of vessels most commonly involving the subclavian artery to internal mammary artery to intercostal arteries and then to the aorta, distal to the coarctation. Rib notching can be seen. Treatment can surgical or balloon angioplasty.
