Coarctation of Aorta
Conditions
Brief summary
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Search for ultrasound risk factors associated with diagnosis coarctation of the aorta | 24h after birth | Calculation of sensitivity, specificity and ROC (Receiver Operating Characteristic) curves of the different ultrasound parameters according to post-natal confirma-diagnosis of coarctation of the aorta in order to create a score to improve the antenatal diagnosis of coarctation the aorta. |
