Coarctation of the aorta, or aortic narrowing (abbreviated as CoA), is a congenital condition whereby the aorta narrows in the area where the ductus arteriosus (ligamentum arteriosum after regression) inserts.: Coarctation (narrowing) of the aorta. 1:Inferior vena cava, 2:Right pulmonary veins, 3: Right pulmonary artery, 4:Superior vena cava, 5:Left pulmonary artery, 6:Left pulmonary veins, 7:Right ventricle, 8:Left ventricle, 9:Pulmonary artery, 10:Aorta.
We have summarised the patients with hypoplastic aortic arch in Table 1. Two of the three patients were female with a mean age of 10.75 years at diagnosis. Two patients had associated coarctation of the aorta and one had a ventricular septal defect (VSD).ue to similarities in the clinical and imaging features of hypoplastic aortic arch and pseudocoarctation of aorta, they may be mistaken for true coarctation leading to unnecessary investigations.
