The goal of this observational study is to assess the correlation between Quantra viscoelastometric assay and laboratory hemostasis biology in a cardiac surgery cohort presenting with acute hemorrhage in the operating room. The main questions it aims to answer are: * is Quantra a valuable surrogate for hemostasis biology in the setting of bleeding cardiac surgery? * are Quantra parameters well correlated with tranfusion thresholds in the setting of bleeding cardiac surgery?
