CTICasesCoarctation of the Aorta with Bicuspid Aortic Valve
Imaging findings
Cardiac CT of a pediatric patient shows a juxtaductal aortic coarctation associated with extensive collateral vessels, including enlarged internal mammary and intercostal arteries. The aortic valve is confirmed to be bicuspid on CT.
Key takeaways
Coarctation of the aorta is a common congenital vascular anomaly frequently associated with other cardiovascular lesions, most notably a bicuspid aortic valve. The presence of extensive, dilated intercostal and internal mammary arteries represents collateral flow bypassing the obstruction.
