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 is a highly accomplished and respected cardiac surgeon, with a wealth of experience and expertise in a variety of surgical techniques and procedures. He completed his undergraduate and medical training at McGill University, before going on to pursue his residency training in cardiac surgery at the University of British Columbia (UBC). He became certified by the Royal College of Physicians and Surgeons of Canada in 2013, after which he completed several fellowships in aortic and endovascular surgery, advanced valve repair, and ventricular assist device/transplant surgery.

Throughout his career, Dr. Yamashita has demonstrated a deep commitment to research, and has published many peer-reviewed articles, book chapters, and abstracts. He has also presented his work at conferences and other events around the world, and has been honored with several awards and accolades for his contributions to the field.

Dr. Yamashita joined the Cardiac Sciences Program as a cardiac surgeon and assistant professor in 2016, and has since taken on several leadership roles within the program. He currently serves as the director of complex thoracic aortic surgery and the director of the Manitoba Thoracic Aortic Diseases Clinic, and is also the surgical co-director of heart failure in the extracorporeal membrane oxygenation (ECMO) program.
