Dr Marco Spartera

Dr. Marco Spartera is an NHS Consultant Cardiologist at both the John Radcliffe Hospital (Oxford University Hospitals NHS Foundation Trust) and the Great Western Hospital NHS. In addition to his NHS roles, he is the director of Oxford Cardiovascular Health Ltd (OCH), a private clinic providing cardiology services across Oxfordshire, Wiltshire, and the Cotswolds.  Internationally recognised for his expertise in multi-modality cardiovascular imaging, Dr. Spartera specialises in diagnosing and managing complex cardiac conditions, including those related to ischaemic stroke, obesity, atrial fibrillation, valvular heart disease, arrhythmias, and heart failure. He also leads clinical services such as the 'stroke-cardiology' and 'valve clinic' at the Great Western Hospital. Dr. Spartera has an empathetic and compassionate approach to his practice, offering consultations via video, telephone, or face-to-face appointments. His patients consistently provide positive feedback, emphasising his ability to deliver clear, actionable cardiology plans that are tailored to each individual’s needs and values. With a special focus on non-invasive cardiac imaging, Dr. Spartera employs advanced diagnostic tools, including cardiovascular MRI, cardiac CT, and sophisticated echocardiography techniques such as trans-oesophageal, bubble, contrast, 3D, and stress echocardiography. His diagnostic expertise is often sought in challenging cases where symptoms are complex or have remained unresolved after multiple consultations. His ability to navigate these intricate cases ensures accurate, timely assessments and personalised care. Dr. Spartera earned his PhD in cardiovascular medicine at the University of Oxford, where he currently leads research into cardiac flow abnormalities, aiming to uncover novel mechanisms of cardioembolism and heart failure. He is also a principal investigator in the LOSE-AF trial, which explores weight loss as a strategy to improve outcomes for overweight/obese patients with atrial fibrillation. His research is supported by the NIHR Oxford Biomedical Research Centre and the British Heart Foundation.
