Congenital heart disease

What is congenital heart disease?
Congenital heart disease is an abnormality of the heart that you are born with. In some cases, the condition is diagnosed when the baby is still developing in the womb, but in most cases the problem is not discovered until after the baby is born.

Congenital heart disease affects about 1 in every 145 births. For more than half of these babies, the condition is a minor problem which either doesn’t need any treatment, or can be successfully corrected with surgery after they are born.

Other conditions are more serious and sadly, some children with congenital heart disease do not survive. However, thanks to advances in early diagnosis and treatment, most children will grow up to become adults and lead full and active lives.

There are many different types of congenital heart disease. For example, the heart’s valves may not be properly formed or there could be holes between the chambers of the heart.

What causes congenital heart disease?

In most cases, something has gone wrong in the early development of the foetus. Some heart conditions are due to faulty genes or chromosomes. Often, we don’t understand why the baby’s heart hasn’t developed normally.

How is the condition discovered?

Many heart problems are picked up when the mother has an ultrasound scan during pregnancy, but sometimes they are not detected until after the baby has been born.

Some conditions may not be discovered until the child is older or even an adult.

What treatment is available?

Treatment depends on the type and severity of the condition. Some children won't require any treatment, while others may need medication or heart surgery. There are also other new techniques and procedures that, in some cases, can be done instead of surgery.

Support for parents and families

Finding out that your child has a congenital heart condition can be very distressing, but there are health professionals and groups who can support you through this time.

If your child is being treated at a specialist centre or hospital, ask if there is a cardiac liaison nurse or social worker you could speak to. They can provide you with practical help and reassurance, and direct you to other useful organisations for further support. Your cardiac liaison nurse will often stay in touch and be available to answer your questions even after your child has been discharged from hospital.
