SPECIALTY AND TITLE
Cardiovascular Surgery, Professor Emeritus and Senior Scientist Emeritus
Toronto General Hospital – University Health Network
University of Toronto
AREA OF RESEARCH
New techniques of cardiac surgery: our studies on cardioplegic protection led to a series of clinical trials which established many of the currently employed techniques.
As Chair of the Cardiothoracic Surgery Clinical Trials Network, we are performing a series of multi-national trials to evaluate new methods to improve cardiac surgery outcomes.
Regenerating injured hearts: we discovered that the implantation of stem cells prevented heart failure after coronary occlusion. The initial animal studies contributed to the rationale supporting extensive clinical trials of stem cell therapy in Toronto and worldwide.
