Biological and Clinical Relevance of Quantra Viscoelastic Hemostatic Assay in Hemorrhagic Cardiac Surgery
Sponsor: Pitié-Salpêtrière Hospital
Summary
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?

Interventions
Viscoelastometric hemostatic assay
As part of usual care, when weaning the patient from CPB during cardiac surgery, blood samples are withdrawn from the patient to assess hemostasis: we test both Quantra viscoelastometric assay and biological hemostasis including QT, ACT, fibrinogen and platelet count
