A multidisciplinary comparison of transfusion and perioperative support for high‐risk cardiac surgery at three large academic centres in North America

Abstract

Cardiac surgery is associated with numerous peri‐ and post‐operative haemostatic complications and blood transfusion requirements. Complex procedures such as redo‐sternotomy heart transplantation or type A aortic dissection repairs are at high‐risk for severe coagulopathy and significant transfusion requirements. However, current practice guidelines do not specifically address high‐risk surgeries, resulting in variable practice. To optimise outcomes, a multidisciplinary approach to blood transfusion and haemostasis is critical. How individual institutions construct these multidisciplinary teams, delegate responsibilities, and build procedures may differ depending on the institution and availability of resources. In this article, we compare how the transfusion medicine services support their cardiac surgery and transplant programs at three large medical centres—Vanderbilt University Medical Center (the largest heart transplant centre in the world by volume in 2021), Toronto General Hospital‐University Health Network (a quaternary‐care centre in Canada's most populous city, performing more >20 heart transplants annually), and Vancouver General Hospital (a quaternary‐care centre that performs numerous high‐risk cardiac surgeries). This article discusses management from multiple perspectives, including the blood bank and perioperative environments, and highlights how institutions have evolved their programs in accordance with nation‐specific policies and provisions.
