One Heart Clinic
One Heart Clinic is a cardiac specialist group that brings together world-class cardiologists from leading teaching hospitals across the UK.
One Heart Clinic was founded by three leading consultant cardiologists – Dr Ravi Assomull, Dr Fakhar Khan and Dr Sayan Sen – who are recognised experts in all areas of heart disease. The clinic has since grown to include more than 38 cardiologists working across several locations.
Using a multidisciplinary approach, the team provides a comprehensive range of non‑invasive heart tests, delivered using the highest quality equipment. They believe the best cardiac care can only be achieved by the best cardiologists in their fields, working together for you and your heart.

This means that whatever treatment or expertise you need, One Heart Clinic can provide support from a specialist in that specific field.
