Coarctation of the aorta is characterized by
narrowing of the distal aortic arch which can lead to
reduced blood flow in the fetal aortic arch, leading to
arch hypoplasia, usually clinically evident after birth.
Coarctation of the aorta is a common congenital
heart defect accounting for about 8% of heart defects.
Prenatal diagnosis of fetal coarctation is always difficult.
It is mainly suspected by ventricular disproportion (left
ventricle smaller than right ventricle). We present the
case of a patient referred to our service for the
management of a suspected fetal heart disease during
pregnancy estimated at 23 weeks of amenorrhea
