The National Institute for Cardiovascular Outcomes Research (NICOR) collates data relating to antenatal diagnosis of congenital heart defects. Currently, their data set is limited to patients treated by surgery or intervention in the first year of life – meaning it is not an overall antenatal detection rate as it doesn’t include terminations; deaths during pregnancy or peri-natal deaths; conditions that don’t require treatment in the first 12 months; cases detected post-12 months; or instances where intervention is decided against due to the complexity of the patient’s condition(s).
However, this is the best data available at this time, and provides a strong indication of antenatal rates in our nations and regions.
