Screening for congenital heart disease prenatally. Results of a 2½‐year study in the South East Thames Region

Abstract

Prenatal screening for some forms of major congenital heart disease is possible by including examination of the four chamber view of the fetal heart in routine obstetric scans. However, there are important limiting factors that will influence the success of abnormality detection and must be taken into account if screening is to be effective nationwide.
