Conditions

Bleeding, Drug Removal, Emergent Cardiothoracic Surgery

Brief summary

TISORB is a study to show that the CytoSorb device removes ticagrelor from blood during surgery in patients who need emergency surgery on their heart. The hypothesis of TISORB is that removal of ticagrelor by the CytoSorb device during surgery will decrease the risk for surgical bleeding from ticagrelor.
