European Recognised Specialist in Veterinary Cardiology
Simon Swift
Simon qualified from Cambridge in 1986 and joined a mixed practice in Cornwall. After 2 years, he realised small animal practice was his passion and moved to a small animal hospital practice in the North West where he started to focus on cardiology. This lead to his attaining the Certificate in Small Animal Cardiology in 1990 and becoming a partner in a large small animal referral emergency and first opinion practice in South Manchester. He stayed there for 15 years developing the practice and particularly the referral side. A month’s sabbatical to Missouri working with a world renown cardiologist, John Bonagura, lead to the consideration of further specialisation. In 2005 he joined Liverpool University Teaching Hospital as a lecturer in cardiology helping to build the referral service offered by the Hospital. This lead to the European Diploma in cardiology and specialist status. In 2009 he moved to his current position as the cardiologist at Northwest Surgeons in Frodsham, Cheshire, a dedicated referral practice.

Simon was asked to attend the 1991 Cavalier Championship show and this has lead to closer ties to the Club over the last 20 years. Simon regularly attends heart testing sessions across the country and advises the Club on cardiac problems particularly degenerative mitral valve disease and the breeding programme. Simon currently maintains the database for the Club.

Mitral valve disease has been a particular interest and Simon has taken part in several clinical trials establishing the optimum treatment for the disease. The most recent of these is the QUEST study.
