Cardiac surgery with extracorporeal circulation is the surgery in which postoperative bleeding is most common. The use of tests to assess coagulation such as thromboelastography or rotational thromboelastometry (ROTEM®) reduces perioperative bleeding and the need for transfusion in cardiac surgery and trauma. As with ROTEM®, the QUANTRA® device allows us to know the deficiency of coagulation factors before leaving extracorporeal circulation and neutralizing heparin with protamine. To evaluate the correlation and agreement of results between the QUANTRA® analyzer based on sonoreometry of sonic estimation of elasticity by resonance (SEER) and the ROTEM® analyzer based on rotational thromboelastometry in cardiac surgery patients with cardiopulmonary bypass. Multicenter, descriptive, prospective study. All patients undergoing cardiac surgery with extracorporeal circulation are included consecutively. All coronary patients with antiplatelet treatment, emergency interventions, reinterventions due to bleeding, hypercoagulable states will be excluded. Multiple variables will be collected such as hemoglobin value, age, sex, need for transfusion of blood products, etc. Both the CT of both systems and the CS of the QUANTRA® will be compared with the A10 of the ROTEM® . The sample size necessary to carry out the study (moderate correlation, type I error 0.05 and type II error 0.20) will be 50 patients. The study has been approved by the research ethics committee of the Hospital La Fe in Valencia. Statistical analysis will be performed using SPSS® version 18.0.1. A level of p
