Dr. Jean-François Légaré

Cardiovascular Surgeon

Dr. Jean-François Légaré is the head of cardiac surgery at the New Brunswick Heart Centre and a professor of surgery, pathology, microbiology and immunology at Dalhousie Medicine New Brunswick.

Dr. Légaré has graduated from McGill University, Faculty of Medicine, in 1995 with training in Cardiac Surgery. He then joined Dalhousie Medical School in 2003 following fellowship training in Germany. From 2003-2016 worked as a cardiac surgeon at the Maritime Heart Centre in Halifax. During this tenure acted as the Director of Research and Director of Cardiac Transplantation in the Division of Cardiac Surgery. He has now taken the position of Head of the Division of Cardiac Surgery (2016-) at the New Brunswick Heart Centre in Saint John NB with continued affiliation with Dalhousie University.

Major clinical interests have included surgery for end stage heart failure and valve surgery with emphasis on clinical outcomes and performance indicators. Research interests have also included the role of immune-cell infiltration/inflammation in development of heart failure, with particular emphasis on fibrosis. Funding for this research work as been from the Canadian Institutes of Health Research (CIHR), Nova Scotia Health Research Foundation, Capital Health (NSHRF), Canadian Foundation for Innovation (CFI), Heart and Stroke Foundation (HSF) and the Dalhousie Medicine Research Foundation (DMRF).
