About Dr O'Sullivan
Dr O'Sullivan was appointed a Consultant Cardiologist in 2004 and was awarded membership of the Medical Advisory Committee of Cambridge Heart Clinic in 2008.
Following undergraduate training at Cambridge University, Dr O’Sullivan undertook postgraduate training at The Royal Brompton National Heart & Lung Hospital and the Oxford University Teaching Hospitals.
He returned to Cambridge in 1996 to complete higher cardiological training with particular emphasis on interventional cardiology. During this period he 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, he worked in the Department of Interventional Cardiology at University of British Columbia, Vancouver and gained extensive experience in advanced interventional techniques and new strategies for the treatment of coronary disease.
Dr O’Sullivan was appointed Consultant Cardiologist at Royal Papworth Hospital and Addenbrooke’s Hospitals in 2004. In this position he provides secondary and tertiary centre care to patients with general cardiac problems (valve disease, heart failure, heart rhythm problems etc.), in addition to those with coronary disease.
Whilst maintaining a busy clinical practice, Dr O’Sullivan has a major role in medical management, having been appointed Clinical Director of the Addenbrooke’s Cardiology Department in 2006.
He serves as regional specialty advisor for Cardiology to the British Cardiovascular Society and the Royal College of Physicians. In addition, he remains active in the research arena, with interests in the invasive assessment and treatment of coronary disease and the exciting field of percutaneous mitral valve repair.
