Congenital heart disease

If you are an existing ACHD patient, find out more about recent changes

Congenital heart disease (CHD) is the term used to describe heart conditions which are present from birth, or have been inherited.

Our adult congenital heart disease (ACHD) centre provides outstanding care for patients with CHD, not matter how complex. It was one of the first, and is now one of the largest, facilities of its kind in Europe and cares for more than 10,000 adults with congenital heart disease - the largest number in the UK. Because CHD is a lifelong disease, more than 70% of those patients have transferred from our  paediatric congenital heart disease service.  

Care for all ages

Here at Royal Brompton and Harefield, we take a vertical model approach to care, which means that from pre-birth and childhood to adulthod, all our CHD patients are cared for in the same place throughout their lives. This is possible because our congenital heart disease services are closely integrated and we can provide our teenage patients with a seamless, coordinated transfer to the ACHD centre. 

 We also care for a number of patients with pulmonary hypertension.  

Our services and facilities

Our ACHD centre offers all types of treatment, including:


We also provide obstetric and gynaecological care for patients with congenital heart disease. This is provided jointly with the high-risk maternity team from Chelsea & Westminster Hospital.

New developments

  • Advanced ACHD heart failure and transplantation clinics run jointly with the transplant team
  • Risk stratification service for serious arrhythmias, run by the ACHD, MRI and electrophysiology teams 
  • The ACHD-PH network and specialist Eisenmenger clinics
  • International preceptorships for overseas consultants to learn about ACHD-PH 

Information for existing patients

If you are already a patient with us, you will be aware that two of the unit’s doctors, Lorna Swan and Rafael Alonso-Gonzalez, left to take up positions at the University of Toronto, Canada, in 2018. We understand that this may have been an unsettling time for many of you but we have, and will continue, to maintain the level of care you deserve as an ACHD patient.

As a result, we have had to make some changes to clinic arrangements, but if you have any concerns about this or any other queries, please contact us on: 0201 351 8764.

These changes do not apply to the rest of ACHD and/or PAH clinics at the moment, although we do anticipate further changes and improvements throughout 2019 as we recruit new consultants and clinical nurse specialists (CNS), to support the service.

We remain committed to providing the best care for you and will keep you up-do-date with any further changes.

Clinic information

Our ACHD clinics now run:


  • Dr Swan's clinic on Monday morning at Royal Brompton Hospital is now covered by Dr Isma Rafiq
  • Dr Alonso's Monday afternoon clinics at Royal Brompton and Harefield hospitals, are now covered by Dr Harith Alam


Dr Uebing's Wednesday afternoon clinic at Royal Brompton Hospital, is now covered by Dr Aleksander Kempny.

All other ACHD and/or PAH clinics will continue as they are at present. 

We are committed to providing patients with the best possible care. If you have any queries about these clinic changes, please contact the ACHD team by emailing or calling 0207 351 8764.

Patient education and empowerment are important components of the ACHD service. The clinical nurse practitioners coordinate education and patient involvement.

Professor Somerville

The centre was established in 1975 by Professor Somerville, one of the founders of the field of adult congenital heart disease (ACHD), at the National Heart Hospital. 

In 1989 the centre (also known as the 'grown-up congenital heart' or GUCH Unit) relocated to Royal Brompton Hospital. Since then the centre has continued to expand and go from strength to strength.

Education & research

As well as being a major research facility for congenital heart disease and cardiac surgery, our ACHD centre also provides national and international specialised training for cardiologists, cardiothoracic surgeons, and allied disciplines. 

Specialist international clinical fellows are an integral part of our centre and contribute to the worldwide reputation of the organisation.

National and international meetings in the field – coordinated from Royal Brompton and the National Heart & Lung Institute – are also an integral part of the programme's academic curriculum. Find out more about Royal Brompton's 12th advanced symposium on ACHD

Members of Royal Brompton Hospital's ACHD centre are sought-after conference speakers and contributors to major literature in this emerging cardiovascular field.  The team strives to share its learning with colleagues worldwide and has produced numerous highly regarded textbooks.
