I am interested in the clinical outcomes of patients with a wide range of aortic disease, including aortic valvular disease, following both conventional surgery as well as endovascular or percutaneous intervention. St. Michael’s Hospital participates in the International Registry of Acute Aortic Dissection study, which prospectively collects data on patients with either Type A or Type B dissections in 24 centers around the world. We are in the process of developing a National Aortic and Endovascular Surgery Registry to prospectively study patients undergoing either conventional surgery or endovascular surgery in major centers across Canada. I am also interested in the basic biology of aneurysm formation and aneurysm regression following endovascular stent-grafting.
