Dr Mark Mason graduated medicine in 1988 from Charing Cross and Westminster Medical School, followed by his speciality training in Cardiology with the London Deanery. In 2001, he qualified as a Consultant Cardiologist. 

His vast expertise covers patients with coronary artery disease, valve disease, heart failure and patients who require or already have a pacemaker or defibrillator. Additionally, he is widely experienced in coronary angioplasty and stenting, including playing a significant role in developing the primary angioplasty service at Harefield since its inception in 2004.

He has developed a subspecialist interest in implanting pacemakers and ICDs, with a particular interest in Cardiac Resynchronisation Therapy (or ‘Biventricular Pacing’) and leads this service at Harefield Hospital. He used to be a specialist advisor to NICE on this area. 

Mark is a keen teacher and is particularly interested in developing the use of simulation-based training for teaching trainee doctors. He regularly lectures and chairs meeting in the UK and internationally.
