About Dr Mark Mason

Dr Mark Mason is a consultant cardiologist who treats private patients at Harefield Hospital, Royal Brompton Hospital, and 77 Wimpole Street.

He qualified in medicine at Charing Cross and Westminster Medical School (now part of Imperial College London), then went on to complete cardiology training with the London Deanery. He has been a consultant cardiologist since 2001.

He has been a specialist adviser to the National Institute for Health and Care Excellence (NICE) on the use of laser sheaths in pacing lead extraction.

He has extensive experience in managing patients with heart conditions such as:

  • Coronary artery disease
  • Valvular heart disease
  • Heart failure
  • Cardiac rhythm disorders, particularly decision making around the need for permanent pacing

He is an expert in a number of cardiac treatments and procedures including:

  • Cardiac resynchronisation therapy (also called ‘biventricular pacing')
  • Implanting pacemakers
  • Implantable cardioverter defibrillator (ICD)

He has a keen interest in sports cardiology- both professionally and as an athlete himself- including screening for the risks associated with participation in endurance sport, particularly in older athletes.

This is the second time Dr Mason and I have met in theatre. He has had to revise work done by others. He is very professional, has a great sense of humour and an easy going manner which makes you feel at ease. I can't thank Dr Mason enough, as I am pain free now after 2 and half years ofhell! He is a life changer. Thank you Dr Mason

The referral was made at my request following treatment at L&d cardiology where I was left feeling somewhat confused and without answers as to what is going on in regards to the episodes I have been experiencing. Dr Mason was able to explain things very clearly and provide next steps to better understand what is happening
