Broussais Hospital, 1983-1989 Gilles Dreyfus started as senior resident/assistant surgeon, before becoming staff surgeon of Professor Carpentier. He acquired a specific training in
mitral valve repair and developed new surgical techniques in valve repair with Professor Carpentier, in particular he performed the first mitral valve repair in case of acute
endocarditis and he published an article on innovative surgical procedures. He also improved the transplant program at the Broussais Hospital, started by Professor Dubost and discontinued after 4 patients. The program developed rapidly: from 1984 to 1989, more than 200
heart transplants were performed at the Broussais Hospital. An
artificial heart project as a bridge to transplant was also developed. In 1986, he helped Professor Carpentier perform the first artificial heart implant in
Europe. During his stay at the Broussais Hospital, Gilles Dreyfus published several articles on heart transplant, such as
Total orthotopic heart transplant: an alternative to the standard technique (Annals of Thoracic Surgery 1991), where he described a new technique called
total heart transplant. He was nominated Professor of Cardiovascular Surgery in 1989 by Professor Alain Carpentier.
Foch Hospital, 1989-2001 In November 1989, Gilles Dreyfus became staff surgeon of Professor Daniel Guilmet at the
Foch Hospital and Professor of Cardiovascular surgery. He performed more than 500 mitral valve repairs and described new repair techniques such as the
papillary muscle repositioning for anterior leaflet and posterior commissural prolapse. He also improved the heart transplant program, from 10 to 25 cases per year, so that the Foch Hospital became the 2nd-3rd most active center in the region of
Île-de-France. Gilles Dreyfus continued the research on artificial hearts as a bridge to transplant, implanting TCI and NOVACOR for the first time in France. In 1998, after Professor Guilmet’s retirement, Gilles Dreyfus became chief of cardiac and vascular surgery of the Foch Hospital, continuing the surgical activity and developing the heart valve repair surgery, the ventricular assist devices and heart transplant programs. In 2000, French actor
Gérard Depardieu underwent
coronary artery bypass surgery performed by Professor Dreyfus.
London : Royal Brompton and Harefield, NHS Trust, 2001-2009 In April 2001, Gilles Dreyfus joined Professor Sir
Magdi Yacoub at the
Harefield Hospital in
London, UK. They worked together for 6 months before Professor Dreyfus became director of the cardio-thoracic surgery in October 2001, following Sir Yacoub’s retirement. He was nominated Professor of cardio-thoracic surgery at the
Imperial College School of Medicine (2nd University of UK) and then became director of the cardio-thoracic surgery and transplantation at the Harefield Hospital. He also continued his research on mitral valve surgery and on
tricuspid valve. In 2003, he presented a research paper at the
AATS annual meeting with a study population of 311 patients, divided in two subgroups: one underwent isolated mitral valve repair, the other mitral valve repair associated to tricuspid valve repair. In this research, professor Dreyfus demonstrated the rationale in treating the tricuspid annulus dilation independently from the presence of
tricuspid regurgitation. This principle influenced the guidelines of the international societies of Cardiology, may it be the
American College of Cardiology /
American Heart Association, or the
European Society of Cardiology. He also focused his research on a new technique to replace the
aortic valve, using autologous
pericardium. Results of this method, called
Cardiomend were presented at the American Society of Thoracic Surgeons annual meeting in 2001 and were the object of two articles. As Director of one of the largest centers for transplantation in Europe, he led a program of heart and
lung transplant and cardiac assist devices. Under his influence, the Harefield group was the first group in Europe to implant the
Jarvik 2000, in addition to other assist devices as destination therapy or as bridge-to-recovery in case of heart failure. While practicing in London, he operated the Queen of Spain's brother, the Queen of England's cousin, the King Constantin of Greece. In 2002, professor Dreyfus, along with three other famous European surgeons specialized in mitral valve repair, developed the
Master of Valve Repair, a training course supported by
Edwards Lifesciences, happening twice or thrice a year, where more than 2000 European surgeons have been trained to advanced techniques in mitral valve repair.
Cardio-Thoracic Centre in Monaco In January 2010, upon the request of Professor Vincent Dor, Gilles Dreyfus was appointed as Medical Director or the Cardio-Thoracic Centre in Monaco, taking over Professor Dor who retired. ==Awards and honours==
