Coarctation repaired adults
Adults who had coarctation of the aorta repaired in childhood are not cured in the everyday sense: hypertension, re-narrowing and aneurysm at the repair site can develop decades later, so lifelong specialist follow-up is essential.

Key points
What matters most, at a glance.
The essentials in plain English - symptoms, when to seek help, who to see and what treatment looks like.
-
Lifelong follow-up in an ACHD centre is recommended for everyone with repaired coarctation
-
High blood pressure is the commonest late issue and may need ambulatory and exercise blood pressure assessment
-
Periodic MRI or CT surveys the repair site for re-coarctation or aneurysm; echocardiography checks the frequently associated bicuspid valve
-
Re-narrowing can usually be treated with balloon dilatation and stenting rather than repeat surgery
-
Pregnancy is usually safe with planning, but needs pre-pregnancy ACHD assessment
Understanding it
About Coarctation repaired adults, and what to do next.
Even a technically perfect childhood repair leaves an aorta that is stiffer than normal and baroreceptors that reset, so hypertension emerges in a large proportion of adults over time - sometimes only on exercise testing. Untreated, it silently drives early coronary disease, which is the main long-term threat in this group.
The follow-up package is well defined: blood pressure surveillance and firm treatment, imaging of the repair site at intervals, and assessment of associated lesions such as bicuspid aortic valve. Many adults repaired decades ago have drifted out of follow-up; re-establishing ACHD care is worthwhile at any age. Most people start with their GP, who can refer to a consultant cardiologist at an adult congenital heart disease (ACHD) specialist centre. In many parts of the UK, routine NHS referrals for this kind of problem currently take 20-45+ weeks, whereas an initial private consultation is typically available within around two weeks.

Frequently asked
Common questions about Coarctation repaired adults.
Quick, plain-English answers to what people ask us most.
-
What does it mean to have repaired coarctation of the aorta as an adult?
Coarctation of the aorta is a narrowing of the main artery leaving the heart, usually present from birth and typically repaired surgically or with a catheter-based procedure in childhood. Adults who had this repaired in childhood need ongoing, lifelong specialist cardiology follow-up, since certain complications can develop or recur even many years after apparently successful initial repair. This lifelong monitoring is an important aspect of care for anyone with this history.
-
What ongoing issues can occur after coarctation repair?
Even after successful repair, adults can develop high blood pressure (which is common even with a technically good repair), re-narrowing at the repair site over time, aneurysm formation at or near the repair site, and, since coarctation is often associated with other heart abnormalities (such as a bicuspid aortic valve), issues with these associated conditions may also need ongoing monitoring. Regular imaging helps monitor for these specific concerns over the long term. This combination of potential issues is why lifelong specialist follow-up, rather than a one-off childhood treatment, is generally recommended.
-
Why is blood pressure often a particular concern?
High blood pressure is common in adults with repaired coarctation, even when the repair itself looks structurally excellent on imaging, and is thought to relate to changes in the blood vessels and how the body regulates blood pressure that developed during the period before repair. Good blood pressure control is particularly important in this group, given the additional stress it can place on the heart and blood vessels, including the repair site itself. Regular blood pressure monitoring, sometimes including exercise blood pressure testing, is an important part of ongoing follow-up.
-
How is follow-up structured for adults with repaired coarctation?
Follow-up typically involves regular consultations with a specialist in adult congenital heart disease, periodic imaging (such as MRI or CT) to assess the repair site and look for aneurysm or re-narrowing, and regular blood pressure monitoring. The specific frequency of monitoring depends on individual factors and how the repair site and blood pressure have behaved over previous reviews. This specialist, ongoing follow-up differs from standard general cardiology care given the specific, lifelong risks involved.
-
Is this condition dangerous if well managed?
With appropriate lifelong specialist follow-up and management of blood pressure and any other issues that arise, many adults with repaired coarctation live full, active lives. However, without ongoing monitoring, undetected complications such as re-narrowing, aneurysm formation, or poorly controlled blood pressure can lead to more significant problems, including a small but recognised risk of aortic complications. This is why continued specialist follow-up, even many years after initial repair and feeling entirely well, remains important.
-
When should I see a specialist?
If you had coarctation repair in childhood 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. 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.
