Coronary Thrombus

The presence of coronary thrombus creates special challenges in the performance of primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI). Large thrombus burden is associated with an increased incidence of distal embolization and no-reflow, and may limit reperfusion at the microvascular level. In addition, large thrombus burden is associated with higher major adverse cardiac event rates and is a strong independent predictor of 2-year mortality (Slide 1).[1] There have been a number of adjunctive strategies to deal with coronary thrombus at the time of primary PCI, and these have included pharmacologic therapies (primarily glycoprotein IIb/IIIa platelet inhibitors), mechanical thrombectomy, embolic protection devices, and manual aspiration.
