Congenital heart disease is a term which covers any heart abnormality present from birth. One in every 133 babies in the UK is born with a heart condition, over 5,000 babies per year.
Acquired heart defect is a term which covers a heart abnormality that develops after a baby is born. An estimated 500 -1000 children each year develop heart conditions after they are born.
Improvements in paediatric heart surgery and clinical care have led to more children with heart conditions surviving into adulthood. The number of adults with heart conditions is now increasing at an estimated rate of 5% per year.
