OP12.03: First trimester cardiac parameters in the early screening of congenital heart disease (CHD) using high resolution flow imaging mode (e‐flow)

In Flanders (the Dutch speaking Northern part ofBelgium) the prenatal detection rate of congenital heart diseases(CHD) is very low. The primary goal of this retrospective study is todetermine the sensitivity, positive and negative predictive value (PPVand NPV) of nuchal translucency (NT) measurement for prenatalCHD diagnosis in a general low risk population and to consider ifNT measurement is an effective screening tool for CHD.
