|Abstract:||Antenatal detection for Congenital Heart Disease (CHD) is poor, but may be improved by adding views to routine ultrasound scanning. From June 2014-July 2015, 600 randomly selected women between 18 to 24 weeks of pregnancy, had a routine 4-chamber ultrasound scan at Mater Dei Hospital view (Basic 4CV). In addition, they completed an Extended Cardiac Ultrasound Examination (ExCUSE) including the left outflow tract, right outflow tract, 5-chamber view and 3-vessel view. All views were timed. The results obtained from the 600 women who received Basic and the ExCUSE scanning were followed-up clinically after delivery of the infants. Validity testing of both 4CV and ExCUSE views was carried out, and the detection rate of CHD compared. During the 12-month period, 61 cases from a total of 4,200 children up to 1 year of age were diagnosed with CHD by Paediatric Echocardiography. 19 were included in the 600-study cohort, of which 12 were detected antenatally, 1 via the 4CV alone, 4 by both the 4CV plus at least 1 of the ExCUSE views and 7 by 1 or more of the ExCUSE views alone. On average, ExCUSE views took approximately 6 minutes longer, yet there was a significant difference between the detection rate of CHD by the 4CV compared with the ExCUSE views (χ2 = 0.031, p=0.05). Sensitivity and specificity of the 4CV were 31.6% and 100%, respectively, and 63.1% and 100%, respectively for ExCUSE views. Antenatal diagnosis of CHD is improved with additional ultrasound views, but this will necessitate staff training and adjustments in clinic schedules to accommodate increased scan time.|
