Abstract
Microembolization of particulate debris during percutaneous coronary intervention (PCI) will lead to various degree of microvascular obstruction, terminating in no-reflow phenomenon observed angiographically. Different methods, including angiography, non-invasive imaging, and assays of myocardial injury markers, have been used for detection of occurrence of microvascular obstruction. The prevalence of, and the adverse prognosis associated with microvascular obstruction have led to the concept and application of distal protection for coronary interventions. While its value has been confirmed in saphenous vein grafts intervention, data is now growing to support use of distal protection devices in native coronaries. Findings from a local registry that reveals the initial experience on use of GuardWire Plus System, a kind of occlusive distal protection device, for elective PCI are discussed herein.
