Clinical benefit of percutaneous coronary intervention (PCI) depends on both angiographic success at lesion site as well as the restoration of adequate macro and microvascular perfusion. The pathophysiology of embolization from coronary lesions during PCI is multifactorial, being more frequently observed in patients with acute coronary syndrome and in those with lesions at saphenous vein graft (SVG). In this population, despite successful epicardial intervention, distal tissue perfusion may still be absent in up to a quarter of all PCI. Multiple devices and pharmacologic regimens have been developed and refined in an attempt to protect the microvascular circulation during PCI. Among them, embolic protection devices have raised as an attractive adjunctive toll due to their ability to retain debris and potentially prevent distal embolization, reducing major adverse cardiac events. Currently, their use has been validated for the treatment of SVG lesions but failed to show effectiveness in the percutaneous approach of acute coronary syndrome patients, including those with ST elevation myocardial infarction.
