Thrombus Aspiration in ThrOmbus Containing culpRiT Lesions in Non-ST-Elevation Myocardial Infarction (TATORT-NSTEMI)

1. mai 2017 oppdatert av: Holger Thiele, University of Leipzig
Whereas thrombus aspiration in patients with ST-elevation myocardial infarction (STEMI) is recommended by current guidelines, there are insufficient data to unequivocally support thrombectomy in patients with non-STEMI (NSTEMI). The Thrombus Aspiration in ThrOmbus containing culpRiT lesions in Non-ST-Elevation Myocardial Infarction (TATORT-NSTEMI) trial is a 400 patient, prospective, controlled, multicenter, randomized, open-label trial. The hypothesis is that under the background of early revascularization, adjunctive thrombectomy in comparison to conventional percutaneous coronary intervention (PCI) alone leads to less microvascular obstruction (MO) assessed by cardiac magnetic resonance imaging (CMR) in patients with NSTEMI. Patients will be randomized in a 1:1 fashion to one of the two treatment arms. The primary endpoint is the extent of MO assessed by CMR. Secondary endpoints include infarct size and myocardial salvage assessed by CMR, enzymatic infarct size as well as angiographic parameters, such as Thrombolysis in Myocardial Infarction-flow post-PCI and myocardial blush grade. Furthermore, clinical endpoints including death, myocardial reinfarction, target vessel revascularization and new congestive heart failure will be recorded at 6 and 12 months. Safety will be assessed by bleeding and stroke. In summary, the TATORT-NSTEMI trial has been designed to test the hypothesis that thrombectomy will improve myocardial perfusion in patients with NSTEMI and relevant thrombus burden in the culprit vessel reperfused by early PCI.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Aktiv komparator: Trombektomi
Manual thrombectomy will be performed in the thrombus aspiration group using an aspiration catheter utilized in daily clinical routine (Eliminate, Terumo Europe, Leuven, Belgium). In the standard PCI group, patients will be treated by conventional PCI according to local practice without thrombectomy.
Annen: Standard percutaneous coronary intervention
In the standard percutaneous coronary intervention (PCI) group, patients will be treated by conventional PCI according to local practice without thrombectomy.
