Antenatal Diagnosis of Coarctations of the Aorta. (CoA)

May 13, 2019 updated by: Hospices Civils de Lyon

Antenatal Diagnosis of Coarctations of the Aorta. Prospective Observational Study.

Prenatal diagnosis of coarctation is difficult because the ductus arteriosus masks the isthmus narrowing. The problem lies in the fact that it is difficult to assert in utero diagnosis and to predict severity of neonatal symptomatology. However, it is essential to try to establish the diagnosis since it has been shown that the prenatal diagnosis improves survival and reduces morbidity.

Pregnant women
Pregnant woman with suspected coarctation of isolated aorta or woman followed in the last 12 for suspected coarctation of the aorta isolated during pregnancy
