Dr Will Davies is a Consultant Cardiologist at Royal Papworth Hospital with specialist interests in percutaneous coronary intervention for coronary artery disease and structural intervention for degenerative valvular disease.

Dr Davies graduated from the University of Sheffield in 1998, gaining clinical distinctions and prizes at Final MB ChB. He then undertook training in Cardiothoracic Surgery, and was awarded Membership of the Royal College of Surgeons in 2001.

During his period of surgical training, Dr Davies was appointed as the William J von Liebig Scholar in Cardiothoracic Transplantation at the Mayo Clinic, USA where he studied towards a Doctor of Philosophy research degree. His work on the role of circulating progenitor cells post cardiac transplantation led to him being honoured with the Mayo Clinic and Foundation Award for Individual Excellence.

On returning to the UK he worked as a Specialist Registrar for 18 months on the cardiac surgery service here at Papworth, including a six month period within the Transplant Team.

Having experienced first-hand the exciting advances in minimally invasive valve therapies whilst in the US, Dr Davies undertook cardiology training within the Eastern Deanery and gained Membership of the Royal College of Physicians in 2009. His Fellowship at St Thomas’ Hospital, London afforded him the opportunity to work alongside the pioneers in the field of minimally-invasive heart valve implantation.

Dr Davies’s unique training in both cardiac surgery and cardiology allows him to understand the relative strengths and weaknesses of both specialties when dealing with the patient with complex cardiac pathology.

Dr Davies is also the driving force behind our Laudit positive reporting system, used by the staff here at Royal Papworth since 2018. The reporting tool allows our staff to provide peer-to-peer recognition and celebrate the everyday extraordinary steps they take to improve the patient experience and to support each other.
