Distal Myocardial Protection During Percutaneous Coronary Intervention: When and Where?

摘要: The discrepancy between angiographic success and microvascular perfusion has been recognized for some time. In the face of an open artery, degree determines post-infarct prognosis. Despite successful epicardial recanalization, tissue may be absent in up to 25% patients with acute myocardial infarction. Historically associated saphenous vein graft intervention, embolization is increasingly native coronary arteries, particularly undergoing primary percutaneous intervention (PCI). With more than two million PCI procedures performed worldwide each year, there enormous interest protecting left ventricular myocardium from during PCI. This article reviews evidence distal protection discusses relative merits different available techniques.
