Abstract

Detection rates of congenital cardiac malformations have traditionally remained low. The NHS Fetal Anomaly Screening Programme (FASP) aims to increase these detection rates for various reasons, including influencing perinatal management and aiding parental decision making. The inclusion of the three vessel view and trachea (3VT) view in 2015 aimed to improve detection rates of arch abnormalities in particular. This study evaluated the early impact of the new initiative at one NHS Trust. Departmental screen-positive rates were compared for a full year before and after implementation. Referrals to, and opinions of, the foetal medicine unit (FMU) were assessed; as were undetected congenital heart defects for the two time periods. Compared with the pre-implementation (pre-3VT) period, the number of completed anomaly scans performed after implementation (post-3VT) increased by 3% and the number of FMU referrals increased by 625%. Departmental screen-positive rates for cardiac abnormalities increased from 40% (pre-3VT) to 91% (post-3VT). Over half (52%) of the FMU referrals were made due to a suspected abnormal 3VT view. Early evaluation of 3VT implementation at this NHS Trust indicates that it has been a success. Departmental screen...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
