Risk Factors for Coarctation of the Aorta on Prenatal Ultrasound

Abstract

The detection rate of CoA may improve when a multiple-criteria prediction model is adopted. Further large multicenter studies sharing the same imaging protocols are needed to develop objective models for risk assessment in these fetuses.

Predictors of Inadequate Mixing in Transposition of the Great Arteries — a Critical Neonatal Condition

“…28,29 In pulmonary atresia with intact ventricular septum, a critical CHD with ductal-dependent pulmonary circulation, the tricuspid valve z score, and the right to left ventricular ratios were described as predictors of outcome in fetuses and neonates as well.…”

Clinical yield of fetal echocardiography for suboptimal cardiac visualization on obstetric ultrasound

“…When there is ventricular size discrepancy and concern for a hypoplastic aortic arch, a false positive diagnosis of arch obstruction is not uncommon. 16,17 Finally, we included the category of "probably normal" to highlight some of the diagnostic uncertainty of fetal echocardiography, which is only increased in the setting of poor acoustic windows. These studies were not expected to have any significant pathology, or had minor pathology that was expected to resolve.…”

Fetal echocardiography for planning perinatal and delivery room care of neonates with congenital heart disease

“…56 The parameters with the highest detection rate of CoA were: (1) hypoplastic aortic arch in fetuses with ventricular disproportion (sensitivity 90%; specificity 87%) ( Figure 6A comparison between models was limited, the model using the angles between the (1) ascending and descending aorta and (2) transverse and descending aorta had the highest sensitivity (95% and 100%, respectively) for predicting CoA of the aorta. 56 The parameters with the highest detection rate of CoA were: (1) hypoplastic aortic arch in fetuses with ventricular disproportion (sensitivity 90%; specificity 87%) ( Figure 6A comparison between models was limited, the model using the angles between the (1) ascending and descending aorta and (2) transverse and descending aorta had the highest sensitivity (95% and 100%, respectively) for predicting CoA of the aorta.…”
