The investigators will test the hypothesis that utilization of a blood and blood component transfusion algorithm guided by the POC Quantra QPlus System in patients undergoing complex cardiac surgery will reduce RBC, plasma, cryoprecipitate, and platelet transfusion during surgery and the first 12 postoperative hours, compared to standard of care (central laboratory transfusion monitoring at the primary anesthesia provider's discretion).
