Heart valve services

We're one of the largest valve disease services in the UK. 

We identify, investigate and treat people with heart valve problems and diseases

We provide:

  • structural heart intervention, using key hole techniques to replace or repair various heart conditions
  • valve disease surveillance
  • surgical valve replacements including minimally invasive techniques
  • post-operative valve surveillance
  • pregnancy planning
  • anticoagulation advice

We see people who have:

  • problems with their valves, such as narrowing or leaking
  • been born with heart valve abnormalities, such as an aortic valve with only 2 cusps (or flaps) instead of 3
  • conditions that mean it might be dangerous to have surgery
  • heart valve disease that cannot be treated with surgery
  • heart murmurs
  • infective endocarditis

We run a number of clinics including:

Our team includes:

  • consultants
  • clinical scientists
  • specialist nurses

We work with other services, including:
