Acute ST segment elevation myocardial infarction(STEMI) is characterized by complete thrombotic occlusion of a major coronary artery. Early recanalization of the infarct-related artery is most efficiently delivered by primary percutaneous coronary intervention(PPCI),however this does not always restore normal myocardial perfusion,mainly due to distal embolization of the thrombus and microvascular obstruction. Early evidence for manual thrombus aspiration during PPCI was promising and this was once considered an important aspect of the procedure,especially in patients with a high thrombus burden. However,a large body of evidence from recent major randomized controlled trials(notably TASTE and TOTAL) does not support the routine use of manual thrombus aspiration in patients with STEMI undergoing PPCI.
