Congenital heart disease refers to any defect of the heart present from birth. It includes structural defects, congenital arrhythmias, and cardiomyopathies. Approximately eight in every 1,000 babies are born with a heart or circulatory condition.
The national congenital heart disease audit's purpose is to improve availability of outcome data to the profession, healthcare managers, public and other stakeholders following surgery or therapeutic catheterisation for congenital heart disease in children and adults in the United Kingdom (UK).
