Jonathan Byrne is an interventional cardiologist who specialises in the treatment of coronary artery disease. This involves the treatment of patients with angina, heart failure, heart rhythm disturbances and high blood pressure. He also treat patients with valvular heart disease with new treatments which do not require an operation, such as TAVI (transcatheter aortic valve implantation) and Mitraclip (percutaneous treatment of the mitral valve). As well as coronary and structural intervention he also carries out a number of imaging tests for the heart including transoesophageal echocardiography and cardiac CT scanning.
Dr Byrne completed his undergraduate medical training in Bristol and then continued general professional medical training in the South-East of England and London. A PhD in the academic department of Cardiology at King’s College Hospital was awarded in 2004; this examined the molecular mechanisms underlying left ventricular hypertrophy.
His training in interventional cardiology was undertaken at King’s College Hospital from 2004, and continued on Vancouver Island, Canada in 2006 as an international fellow along with transoesophageal echocardiography and cardiac CT scanning. Since his appointment as a consultant in 2008 he has also been involved in the development of the structural programme at Kings College Hospital, with the use of novel percutaneous techniques to treat aortic and mitral valve disease.
His general cardiology interests include the assessment and treatment of coronary and valvular heart disease and risk stratification. He also treats hypertension and general heart rhythm disturbances. Interventional, catheter based treatment of artery or valve disease forms the mainstay of his clinical practice. This includes the treatment of narrowed, diseased heart arteries with angioplasty and stents, with the majority of procedures performed form the radial (wrist). In the past few years, the catheter based treatment of valvular heart disease has formed a much larger proportion of his clinical practice, with percutaneous treatment of the aortic valve (TAVI) and mitral valve (Mitraclip). His interests also include transoesophageal echocardiography to assess structural heart disease, and cardiac CT scanning to screen and assess patients with potential coronary disease.
His research interests have included the molecular mechanisms which underlie the development of left ventricular hypertrophy, and the application of coronary physiology in an interventional setting. His research has also explored the differences and potential advantages of intervention performed form the radial artery.
