Congenital Heart Disease

Child plays with toy - British Heart FoundationCongenital heart diseases are structural abnormalities of the heart which are present from birth.

They affect around 4,600 babies born in the UK every year - babies like Niamh, who was diagnosed with a rare heart condition at the age of just 13 weeks.

Doctors are able to diagnose and treat many congenital heart defects today, thanks partly to decades of research discoveries that have gone before.

Niamh's grandmother Marilyn reflects on their experiences: "The facilities, the equipment and the care, were second to none.

Although it was a harrowing time we were privileged to receive the benefits of all the hard work of research over the years.

Niamh had to have an operation, but just a week afterwards in October 2006 she was recovering so well that her parents were able to take her home in plenty of time for a very special Christmas.

The impact of advances in diagnosis, treatment and care is stark - in the 1950s around eight out of ten babies with a complex congenital heart condition died before their first birthday.

Today, thanks to advances in treatment and care, more than eight out of ten babies with congenital heart disease grow up to be adults. Find out more with our 50 years of heart health timeline.

Mapping heart defects

Now retired, BHF Professor Robert Anderson and his team at the Institute of Child Health mapped out the details of heart defects.

This knowledge, combined with advances in imaging technology, means cardiologists can give these babies the best chance of life, by identifying and treating abnormalities as early as possible.

The 'switch' procedure

BHF Professor Sir Magdi Yacoub developed surgical techniques to treat complex congenital defects. The ‘switch’ procedure is now used to correct a defect in babies born with wrongly connected heart vessels. 

Specialist support

A network of specialist BHF heart nurses provides vital care and support to patients and their families across the country.

As they grow, these patients now have access to specialist support throughout their lives thanks to BHF Professor John Deanfield and Dr Jane Somerville, who established the new cardiology speciality of grown-up congenital heart disease (GUCH).

What’s next?

We continue to support research to improve the understanding, diagnosis and treatment of congenital heart disease.

Teams across the country - including those led by BHF Professors Bernard Keavney and Shoumo Bhattacharya - are investigating the genetics behind why some babies are born with heart defects, with the ultimate aim of preventing them altogether.
