Antenatal Diagnosis of Coarctations of the Aorta.

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.

Inclusion Criteria:

• pregnant or having given birth in the last 12 months in one of the participating centers
• have had an ultrasound screening in the 2nd or 3rd trimester
• addressed or being addressed to the Pluridisciplinary Center for Prenatal Diagnosis for suspected coarctation of isolated aorta in front of: ventricular asymmetry at the aegis of the left ventricle or the large vessels at the aorta, discovered during a screening ultrasound second or third quarter.
• be able to understand and follow the ins and outs of the study
• Have been informed of the study and have not objected to it

Exclusion Criteria:

• Associated complex cardiac disease (transposition of large vessels, atrioventricular duct, right ventricle with double outlet) with the exception of inter ventricular communications
• Left ventricular hypoplasia
• Suspicion of interruption of the aortic arch
