We are a national referral centre for several rare heart diseases, including pulmonary hypertension, carcinoid heart disease, amyloidosis, and glycogen storage disorders. 

The Royal Free Hospital is a campus of the University College London Medical School. The cardiology department undertakes a large amount of research and takes part in key national and international heart studies.

Conditions we treat

  • hypertrophic cardiomyopathy
  • dilated cardiomyopathy
  • arrhythmogenic cardiomyopathies
  • restrictive cardiomyopathy
  • myocarditis and other non-specific cardiomyopathies.


The clinical team is supported by several clinical research fellows with ties to University College London. We have innovated in the development of excellent care for our patients.

Our cardiac catheter (cath) laboratories

Royal Free Hospital

Our dedicated diagnostic department specialises in invasive coronary investigations, featuring two cardiac catheter labs and a 10-bed day-case coronary interventional unit. As one of London's premier heart attack centres, we provide 24/7 on-call emergency services for those who have experienced a cardiac event.

Distinguished for operating the largest standalone percutaneous coronary intervention (PCI) site in London, we perform approximately 1,500 invasive procedures annually, including diagnostic angiography and coronary artery stenting. 

Patients benefit from state-of-the-art technologies like optical coherence tomography (OCT), advanced intra-coronary imaging, and innovative adjunctive therapies like 'shock-wave' therapy supported by artificial intelligence (AI). These advancements enhance the effectiveness of treatments, ensuring optimal results. Our commitment to patient well-being extends to those attending as day cases.

Our dedicated day interventional unit provides personalised care in a comforting environment with a lounge to encourage post-procedure mobility. Experience unparalleled cardiovascular care at the Royal Free Hospital, where technology meets compassion for you and your loved ones.

Barnet Hospital 

Our cardiac catheter laboratory at Barnet Hospital provides high quality care for patients requiring a wide range of cardiac rhythm management procedures. These procedures include invasive electrophysiological studies and ablation; facilitating the accurate diagnosis and treatment of heart rhythm disturbances.

A wide range of cardiac pacing procedures, including pacing for slow heart rates, pacing to improve cardiac function (CRT) and implantation of both transvenous and subcutaneous implantable cardioverter defibrillators (ICDs). We are a pioneering centre delivering pacing directly to the hearts own conduction system where needed aiming to deliver near normal activation of the heart when pacing is delivered. 

You will receive an appointment letter and text message notifying you of your clinic appointment. At the clinic visit you will be asked about your family history and their history of heart conditions. Please remember to bring along relevant medication lists, family information including any autopsy reports or clinic letters if appropriate, and details about your previous medical history.

Royal Free Hospital

The CIU at Royal Free Hospital provides a wide range of outpatient and inpatient clinical and diagnostic services that have a key role in diagnosing and treating heart conditions.

The CIU provides different investigations such as Echocardiograms, Stress Echocardiograms, Bubble and Contrast Echocardiograms, Transesophageal Echocardiograms, Electrocardiograms, Exercise Tolerance Testing, Ambulatory 24 hour ECG (Holter) and Blood Pressure monitoring and also pacemaker clinics/follow ups.

Barnet Hospital and Chase Farm Hospital 

The unit at our Barnet Hospital site is the main cardiac device implanting centre for the Trust.  The team implant a wide range of cardiac devices including Pacemakers, ICDs, CRT-Ds, CRT-Ps and ILRs. 

We also follow up cardiac device patients in regular face to face device clinics and we also have a very well-established remote monitoring service, where we can carry out cardiac device checks remotely via monitors in patients’ homes.

At Barnet Hospital and Chase Farm hospital, our diagnostic departments provides different investigations like:

  • Echocardiograms
  • Stress echocardiograms
  • Bubble and contrast echocardiograms
  • Electrocardiograms
  • Exercise tolerance testing
  • Ambulatory 24 hour ECG (Holter) and Blood Pressure monitoring
  • Pacemaker clinics/follow ups.

Our rapid access chest pain clinic (RACPC) provides prompt specialist assessment for patients with chest pain that suggests angina, and for patients not currently under a cardiologist who have known ischaemic heart disease (a previous percutaneous coronary intervention — PCI, or coronary artery bypass graft — CABG) and have experienced a recent increase in symptoms of chest pain.  The service is available at Royal Free hospital, Edgware Community Hospital and Barnet and Chase Farm Hospitals.

The RACPC service aims to see all patients for outpatient assessment within four weeks of being referred.

The service provides:

  • assessment for suspected angina (including diagnostic cardiac investigations)
  • treatment to relieve symptoms and reduce risk
  • information on treatment options/modifiable risk factors

Patients with suspected myocardial infarction (MI) or acute coronary syndrome should be sent directly to the emergency department (A&E). 

We run clinics at different sites within our trust. Each clinic is run by cardiac specialist nurses and is supported by our clinical lead consultant.

Please note, this is a nurse-led clinic. Patients requesting to be seen by a doctor only will need to be referred to the general cardiology clinic.

The service includes a range of outpatient diagnostic tests, including echocardiography, Holter heart monitors and blood pressure monitors.

There are also one-stop community clinics at the hospital, where patients can have their test and see a hospital consultant on the same day, to speed up time to diagnosis and treatment.

Referrals to the cardiology team can be made via a GP or hospital doctor. Patients cannot be seen without an appointment.

Electronic referrals from a GP are made through the NHS e-Referral Service. Tertiary referrals (from other hospital consultants) are also available.

A referral from your GP will not automatically lead to an outpatient appointment at one of our hospitals. Referrals to the cardiology team are reviewed by a clinician and then one of the following happens:

  1. You will receive an outpatient appointment at one of our hospitals.
  2. You will receive an appointment for a test or an investigation before your first outpatient appointment. 
  3. You and your GP will receive a letter explaining how best to manage your symptoms. This is if one of our clinicians has reviewed your symptoms and does not think you need to attend an outpatient appointment.

More information about what to expect when you are referred to the Royal Free London can be found on our outpatient page.
