Role of thromboelastography in predicting and defining pump thrombosis in left ventricular assist device patients

•TEG derived coagulation index (CI) has been shown to represent “normocoagulability” in mechanical circulatory support patients•We compared serial CIs over time in LVAD patients who had suspected pump thrombosis (PT) to those who did not•Compared to non-PT group, suspected PT group had significantly higher mean changes in CI when followed to 24 months•This suggests mean changes in CI may be useful in predicting suspected PT, and TEGs can be considered in routine follow-up
