Dr Mark Philip Cassar

Dr Mark Cassar is a Consultant Cardiologist with specialist expertise in advanced cardiac imaging, including echocardiography, cardiac MRI and cardiac CT. He sees patients with a wide range of heart symptoms and cardiovascular conditions, including chest pain, breathlessness, palpitations, heart valve disease, heart failure, cardiomyopathy, hypertension, high cholesterol and cardiovascular risk assessment.

His approach is based on careful clinical assessment, clear explanation and the appropriate use of cardiac investigations. Consultations usually include a detailed history, examination and discussion of the most suitable next steps. Where appropriate, an echocardiogram can be performed on the same day, with further imaging arranged if needed.

Dr Cassar trained in cardiology at Oxford University Hospitals and completed a PhD in cardiac imaging at the University of Oxford, where his research focused on the effects of viral infections on the heart. He graduated in medicine from the University of Malta.

He holds the highest level of accreditation in echocardiography, cardiac MRI and cardiac CT. This combination allows him to advise on, perform and interpret the imaging tests most relevant to each patient’s clinical presentation.

Alongside his clinical practice, Dr Cassar holds several national and international professional roles. He is an Executive Committee Member of the British Society of Cardiovascular Imaging, a Taskforce and Leadership Working Group Member of the British Society of Echocardiography, a National Echocardiography Examiner, and the UK echocardiography representative to the European Society of Cardiology.

He has published extensively in peer-reviewed medical journals, including The Lancet, and remains actively involved in cardiovascular research and education. His clinical work brings together general cardiology and advanced imaging to support accurate diagnosis, risk assessment and treatment planning.
