The ratio of pulmonary to aortic valve diameters was the most reliable echocardiographic parameter for predicting aortic coarctation, with 80% of confirmed cases showing early signs.
Do specific fetal echocardiographic features, such as the PV/AV diameter ratio and aortic isthmus z-score, predict the postnatal development of aortic coarctation?
Fetal echocardiographic parameters, specifically the PV/AV diameter ratio and aortic isthmus z-score, are reliable predictors for the postnatal development of aortic coarctation.

ABSTRACT Purpose Aortic coarctation (CoA) is a congenital structural anomaly with one of the lowest detection rates among heart diseases. Improving diagnostic rates allows for the centralization of high‐risk cases in hospitals with pediatric cardiac surgery facilities, thereby reducing neonatal mortality and morbidity. This study aims to evaluate new diagnostic protocols to enhance the clinical and outpatient management of suspected CoA cases. Methods A retrospective analysis was conducted, focusing on various echocardiographic parameters to identify the most predictive indicators for CoA. Results A total of 184 cases with a prevalence of right‐sided heart sections were identified, with 128 patients meeting the inclusion criteria. Of these, 15 cases of CoA were confirmed postnatally, representing 11.7% of the cohort. Among these, 80% showed early echocardiographic signs of CoA. The ratio of pulmonary valve (PV) to aortic valve (AV) diameters emerged as the most reliable parameter, especially in early gestation, while the z ‐score of the aortic isthmus was also a strong predictor. Conclusion The use of simple, reliable echocardiographic parameters can improve the detection rate of high‐risk CoA cases, enabling better clinical management and improved neonatal outcomes in both the short and long term.
