Advantages of MGuard coronary stent system

Effectiveness of percutaneous coronary intervention (PCI) within thrombus containing lesions (ST-segment elevation myocardial infarction setting, degenerated saphenous venous grafts) is limited by the risk of occurrence of distal embolization and no-reflow phenomenon. Several pharmacological agents, as well as mechanical devices (i.e. manual aspiration catheters/mechanical thrombectomy, proximal and distal protection devices) were introduced, in the last years, to reduce the risk of angiographic complications during percutaneous coronary intervention and to improve myocardial reperfusion. Recently, the MGuard stent (Inspire MD, Tel Aviv, Israel), a bare-metal stent covered by micron level mesh, which allows to prevent distal embolization by blocking the atherothrombi prolapse through the stent struts during deployment has been introduced. This article discusses the data concerning safety and efficacy of mesh covered stent implantation in a ST-segment elevation myocardial infarction setting, as well as during percutaneous coronary intervention in saphenous venous grafts.
