Key result
Antenatal ultrasound using the objective AV/PV ratio was the most promising marker for predicting postnatal coarctation of the aorta (AUC 0.81; 95% CI 0.67-0.94).
Why the study?
The study was conducted to assess the performance of antenatal ultrasound markers in detecting neonatal coarctation of the aorta.
Do objective sonographic markers improve the prenatal detection of neonatal coarctation of the aorta in fetuses with suspected CoA?
Population
83 fetuses with suspected CoA and no other cardiac abnormalities
Comparison
Neonates with confirmed CoA vs without confirmed CoA postnatally
Design
Retrospective study

AV/PV ratio may aid fetal CoA detection; leaves open routine adoption pending prospective validation.

Do objective sonographic markers improve the prenatal detection of neonatal coarctation of the aorta in fetuses with suspected CoA?
Effect estimate: AUC 0.81 (95% CI 0.67-0.94)
Objective sonographic markers, particularly the aortic to pulmonary valve ratio, show promise in improving the prenatal detection of neonatal coarctation of the aorta.
Lee et al. (2023) conducted an observational in Coarctation of the aorta (n=83). Antenatal ultrasound markers (AV/PV ratio) was evaluated on Prediction of postnatal CoA (AUC 0.81, 95% CI 0.67-0.94). Antenatal ultrasound using the objective AV/PV ratio was the most promising marker for predicting postnatal coarctation of the aorta (AUC 0.81; 95% CI 0.67-0.94).
