Although coarctation of the aorta cannot be prevented, it can be detected early with fetal echocardiography. Although the diagnosis can be difficult to make, echocardiography may be considered in fetuses with unexplained enlargement of the right ventricle, difficult identification of the true aortic arch, identification of an unusual aortic arch contour, or identification of anomalies that may be associated with coarctation of the aorta, such as other forms of left heart obstruction. Fetal echocardiography is indicated during pregnancy in every woman who has previously borne a child with congenital heart disease (CHD), especially left heart obstructive lesions.

Postnatally, early detection of coarctation of the aorta is important to avoid prolonged hypertension or other complications. Careful measurement of BPs and evaluation of lower extremity pulses in newborns and at subsequent healthy child examinations is imperative.
