Research interests


Research summary

Dr. Yamashita’s research interests include aortic disease, heart failure and clinical outcomes post-cardiac surgery. He is currently examining the prevalence and incidence of thoracic aortic disease in Manitoba and the intermediate term outcomes of patients undergoing mechanical circulatory support. He serves as the site principal investigator at St. Boniface Hospital for the Left Atrial Appendage Occlusion Study III (LAAOS III) and the Post-Surgical Enhanced Monitoring for Cardiac Arrhythmias and Atrial Fibrillation Study (SEARCH-AF), both of which are randomized controlled trials.


Dr. Michael Yamashita completed his undergraduate and medical training at McGill University. He then pursued his residency training in cardiac surgery at the University of British Columbia (UBC) becoming certified by the Royal College of Physicians and Surgeons of Canada in June 2013. Dr. Yamashita then completed fellowships at UBC in transapical aortic valve replacement and ventricular assist device (VAD)/transplant surgery, at Northwestern Memorial Hospital in advanced valve repair, aortic surgery and VAD/transplant surgery, and at the Cleveland Clinic in aortic and endovascular surgery.

Dr. Yamashita earned a master of public health at Harvard University focusing on Epidemiology and Biostatistics. He has a strong publication record of peer-reviewed articles, book chapters and abstracts and has presented his work internationally. In October 2011, he was awarded the Dr. Paul Cartier Cardiac Surgery Resident Award which is given annually to a resident who has made an outstanding contribution to the field of cardiac surgery through research and who has demonstrated promise for a distinguished academic career.

Dr. Yamashita joined the Cardiac Sciences Program as a Cardiac Surgeon and assistant professor in August 2016. He was appointed the director of complex thoracic aortic surgery and director of the Manitoba Thoracic Aortic Diseases Clinic in July 2017. As well, he has served as the surgical co-director of heart failure in the ECMO program since July 2018.
