The Division of Cardiovascular Surgery operates as a component of the Labatt Family Heart Centre, which includes Cardiology, Cardiac Surgery, Cardiac Intensive Care and Cardiac Research. 

The Labatt Family Heart Centre is an evolving structure that may ultimately include other clinical groups; however, these are the areas of expertise required for the care - and for the progress in care - of the congenital heart patient. Our strategic directions and daily accountability occurs within that structure.

The Division is staffed by a team of six cardiovascular surgeons. Click on the directory links below to reveal more about their research interests, achievements and bios.
