Thromboelastometry - diagnostic examination method of clot formation in pigs subjected to experimental procedures of the left atrial appendage

Abstract

The aim of the study was to evaluate the usefulness of thromboelastometry in evaluations of the blood clotting system in pigs subjected to clip occlusion of the left atrial appendage. In this study, blood samples for thromboelastometry were collected, after clip occlusion of the left atrial appendage, from five pigs, in order to assess clot quality formation. Thromboelastometry with three ROTEM assays were performed: INTEM, EXTEM and FIBTEM. Results of the test were presented in TEMograms. The shape of the graph demonstrates hypercoagulability. In the thromboelastometry examination clot quality was stable in all animals.
