Use of 4-Dimensional Sonography in the Measurement of Fetal Great Vessels in Mediastinum to Distinguish True-From False-Positive Coarctation of the Aorta

Gestational age‐specific scoring systems for the prediction of coarctation of the aorta

“…16 Moreover, they are objective measurements less prone to errors than the subjective and difficult assessment of the morphology of the aortic arch, either in 2D or with 3D-4D, the evaluation of the isthmus-ductal angle, or the Doppler analysis of flow disturbances, which have been also proposed as predictive parameters. 1,16,17,24,25 The cardiac parameters selected after multivariate adjustment differed between both diagnosis groups: in the early group, cardiac parameters directly related to aortic dimensions were the best predictors; whereas in the late group, the most predictive markers were indirect signs. In this sense, it is noteworthy that although true CoAo displayed similar echocardiographic features throughout pregnancy and it was not different regarding the GA at diagnosis (≤28 and >28 weeks), normal fetuses with late onset cardiac asymmetry had significantly smaller z-scores of the aortic isthmus than false positive cases of the early group.…”

“…These measurements are usually included in the evaluation of fetuses diagnosed with most CHD and have good interobserver and intraobserver reproducibility .

Diagnostic prénatal des coarctations de l’aorte

“…Cela fut rapporté par différents auteurs dans le cadre de l'analyse biométrique et morphologique de l'isthme aortique [35][36][37][38].…”

Fetal “Aortic Coarctation” and Different Neonatal Follow-Up in 3 Cases

“…In cases 2 and 3 value of PA/Ao ratio (there were 1,2 and 3,68, but false positive with narrowed aortic arch should be 1,6+/-0,23) didn't allow to exclude CoA assumption. The difference between Ao and PA dimensions in the three vessel view shows that PA/Ao is relevant parameter 18 in the CoA diagnosis. Thanks to that we could identify a group of patient who will need monitoring during prenatal life [19][20][21] , prostin infusion and probably surgical intervention in the first days of postnatal life.…”
