Seek urgent help for blackouts, sustained palpitations or breathlessness at rest - and tell any treating team about your heart history
-
Specialist: a consultant cardiologist usually leads assessment and treatment
-
Care includes surveillance imaging in an ACHD (adult congenital heart disease) centre, arrhythmia management, timely repeat interventions, and specialist advice on pregnancy and exercise
Understanding the condition
What it is and what happens next.
What causes it, how it is diagnosed, and the treatment routes available in the UK.
What it is and how it feels
Surgical success means most children born with heart defects now reach adulthood - but repaired is not cured. Valves and conduits wear, chambers can dilate, rhythm disturbances become more common with age, and each defect has its own long-term pattern. Many adults were discharged from follow-up in earlier eras and are unaware they still need surveillance.
Diagnosis and treatment routes
The evidence is clear that adults with moderate or complex defects do best under specialist ACHD centres, which combine congenital-trained cardiologists, imaging, electrophysiology and pregnancy planning under one roof. If you had a heart repair as a child and are not under follow-up, re-establishing contact is one of the most valuable steps you can take. In many parts of the UK, routine NHS referrals for this kind of problem currently take 20-45+ weeks, whereas an initial appointment with a private consultant is typically available within around two weeks.
Seeing a specialist
Who to see, and how quickly you can be seen.
The specialist for this condition is usually a consultant cardiologist. Your GP can refer you on the NHS, or you can arrange a private consultation directly.
A quiet reminder

Your GP knows your history and can tell you which parts apply to you. If in doubt, see them - and seek urgent care for any of the emergency symptoms described above.
Frequently asked
Common questions about Congenital heart disease in adults.
Quick, plain-English answers to what people ask us most.
-
What is congenital heart disease in adults?
Congenital heart disease refers to structural heart abnormalities present from birth, and with significant advances in paediatric cardiac care, the majority of people born with these conditions now survive well into adulthood, creating a growing population of adults living with congenital heart disease, whether repaired, partially repaired, or unrepaired. This group requires specialised, lifelong follow-up given the specific and sometimes evolving issues that can arise even many years after childhood treatment. It is an increasingly recognised and important area of adult cardiology care.
-
What ongoing issues can adults with congenital heart disease face?
Depending on the specific original heart condition and any treatment received in childhood, adults can face issues including heart rhythm problems, heart valve issues, heart failure, and, for certain conditions, ongoing monitoring for specific structural concerns such as aneurysm formation at a previous repair site. Some issues may not become apparent until decades after apparently successful childhood treatment. This is why lifelong, specialised follow-up, rather than assuming a childhood 'fix' means no further monitoring is needed, is so important for this specific patient group.
-
Why is specialised adult congenital heart disease follow-up different from standard cardiology care?
Adult congenital heart disease specialists have specific expertise in the unique long-term issues that arise from congenital heart conditions and their childhood treatments, which differ considerably from the more common acquired heart conditions (like coronary artery disease) that general adult cardiology typically focuses on. This specialised knowledge helps ensure appropriate, condition-specific monitoring and timely intervention if problems develop. Many regions have dedicated adult congenital heart disease services or clinics specifically for this reason.
-
Can adults with congenital heart disease live normal lives?
Many adults with congenital heart disease, particularly those with less complex conditions or successful childhood repair, live full, active lives with appropriate ongoing specialist follow-up. Those with more complex underlying conditions may have some limitations or need more intensive ongoing management, but even in these cases, appropriate specialist care generally allows a good quality of life. Individual outlook depends significantly on the specific underlying condition and how it has been managed over time.
-
What does ongoing monitoring typically involve?
Monitoring typically includes regular consultations with an adult congenital heart disease specialist, periodic imaging (such as echocardiography or, for certain conditions, MRI or CT) to assess heart structure and function, and monitoring for heart rhythm problems. The specific frequency and type of monitoring depends on the individual's specific underlying condition and history. This structured, ongoing approach helps catch and address any emerging issues in a timely manner.
-
When should I see a specialist?
If you have congenital heart disease and are not currently under specialist adult congenital heart disease follow-up, or haven't been reviewed in some time, it's worth arranging this even if you feel entirely well. NHS adult congenital heart disease clinics can have variable waiting times; a private consultation with a specialist in this area is typically available within about 2 weeks for earlier assessment.
