— RISTRATAVIOfficial title:
Risk Stratification for Subclinical Leaflet Thrombosis Post TAVI Using Thromboelastography
Transcatheter aortic valve implantation (TAVI) has become the standard of care in elderly patients at increased risk for surgical aortic valve replacement . However, the optimal antithrombotic strategy post TAVI is still unclear. Current European guidelines recommend dual antiplatelet therapy (DAPT) for 3 to 6 months.The prevalence of subclinical leaflet thrombosis after TAVI is 15% up to 40%, but its clinical long-term relevance is uncertain. Thromboelastography (TEG(R)) can be used as a point-of-care system evaluating a patient's individual hemostasis profile. For the detection of transcatheter valve thrombosis it may be superior to conventional platelet function testing because global hemostasis can be assessed in addition to platelet function. The investigators intend an observational trial recruiting patients undergoing TAVI under standard care. At defined time points the investigators will serially perform TEG(R) as well as further platelet function testing (multiple electrode aggregometry) and conventional coagulation testing. The primary objective is to find surrogate TEG-derived markers / models predicting the development of a subclinical leaflet thrombosis after TAVI under usual care. The secondary objective is to find TEG-derived markers / models identifying patients at an increased risk after TAVI (all-cause mortality, cardiovascular mortality, thromboembolic and bleeding events).
