چکیده
Background: The prenatal diagnosis of coarctation of aorta (CoA) remains a major challenge, as the false-positive diagnosis is fairly common. The purpose of this study was to find some useful prenatal sonographic markers compatible with the postnatal diagnosis of CoA.
Methods: The study included fetuses suspected of CoA in the second and third-trimester ultrasound tests. All cases were examined by fetal echocardiography at a single ultrasound clinic between 2019 and 2020. The proportion of right and left ventricular size was assessed and ductal/isthmus diameter ratio was measured. A comparison was drawn between the results of neonates with neonatal CoA and neonates without CoA.
Results: Of 20 fetuses with suspected prenatal CoA, 3 (15%) had neonatal CoA. The mean ductal/isthmus ratio was significantly higher in the neonates with CoA (1.96 vs. 1.46; p< 0.001). The diagnostic power of ductal/isthmus ratio to detect CoA with a cut point of 1.53 had a sensitivity and specificity of 100% and 70.6%, respectively, a positive and negative predictive value of 37.5% and 100%, respectively, and an overall accuracy of 75%.
Conclusion: The ductal/isthmus ratio diameter and ventricular disproportion are significant sonographic markers for the prenatal diagnosis of CoA, and the ductal/isthmus ratio has high sensitivity and specificity compared to postnatal findings.
