Virtual consultations:

I have worked as a consultant cardiologist in Cambridge for 10 years and am based at Addenbrooke's Hospital and Papworth Hospital. I have extensive experience in all aspects of general cardiology and a subspecialty interest in interventional cardiology.

Following undergraduate training at Cambridge University, I undertook postgraduate medical training at The Royal Brompton National Heart & Lung Hospital and the Oxford University Teaching Hospitals. I returned to Cambridgeshire in 1996 and trained in all aspects of cardiology, with particular emphasis on interventional cardiology, at Papworth and Addenbrooke's Hospitals. During this period I was awarded a PhD and the British Cardiac Society Young Research Worker's Prize, for research into mechanisms of coronary stent failure. From 2003-2004, I worked in the Department of Interventional Cardiology at University of British Columbia, Vancouver gaining extensive experience in advanced interventional techniques and strategies for the treatment of coronary disease.

Following my return I was appointed Consultant Cardiologist at Papworth and Addenbrooke's Hospitals. In this position I provide secondary and tertiary centre care to patients with general cardiac problems (valve disease, heart failure, heart rhythm problems), in addition to those with coronary disease. I am one of the members of the Papworth transcatheter aortic valve implantation (TAVI) team. I was Director of the Addenbrooke's Cardiology Department from 2006 to 2014.

I maintain a keen research interest, with a particular focus on coronary physiology, novel techniques for treatment of coronary disease, and percutaneous techniques for treatment of valvular heart disease.

Echocardiography and exercise testing are available at the time of consultation at my Spire Cambridge Lea Hospital clinic.
