Why the study?
Does extended foetal echocardiography screening improve the detection of congenital heart defects in low-risk pregnancies compared to basic screening?
Population
Pregnant women undergoing routine second trimester (18-20 weeks) anomaly scan for congenital heart defects

Extended screening may improve low-risk CHD detection; leaves open feasibility of training and audit systems pending prospective validation.
Does extended foetal echocardiography screening improve the detection of congenital heart defects in low-risk pregnancies compared to basic screening?
Extended screening protocols improve prenatal detection of congenital heart defects but require specialized training and audit systems to maintain high sensitivity in low-risk populations.
Clur et al. (2014) studied this question.
