Abstract

The authors would like to present an audit on the detection rate of congenital anomalies done in a busy district general hospital. The aim of our study is to look into the detection of congenital anomalies over a period of 12 months (January 2005 to December 2005). Also the authors reviewed the anomalies that were missed antenatally. The standards were the detection rates from Congenital Anomaly Registry and Information Service for Wales. The incidence of anomalies was 5% in our study (163/3580 deliveries).

50% (83/163) were detected antenatally and 47% (n=77) were missed and two patients had insufficient details. Results are as follows:

12% (n=10) were detected before 16 weeks and 76% (n=63) were between 16 and 24 weeks and the rest being over 24-week gestation. Of these 33% (n=26) had termination of pregnancy, 7% (n=6) had fetal demise and 65% (n=51) had live births.

Out of the 78 anomalies that were missed 42% (n=33) were cardiac anomalies with one being atrio-ventricular septal defect and two were transposition of great vessels. Our unit criterion includes only four-chambered view of the heart as an essential criterion and further to this audit, the authors have recommended that the outflow tracts to be included.

To conclude the detection rate was 100% for major anomalies and 37% for cardiac anomalies. The inclusion of cardiac outflow tracts is under review.
