MGuard is a bare-metal stent covered by an ultrathin polymer mesh sleeve on its external surface, designed to reduce embolization during coronary, cerebrovascular and peripheral interventions. AIM: To evaluate the feasibility and safety of MGuard-based percutaneous coronary interventions (PCIs) of human native coronary arteries (NCs) and coronary vein grafts (VGs). METHODS: MGuard-based PCI executed by 2 centers with postprocedural clinical and laboratory monitoring; including creatinine phosphokinase (CPK), troponin, electrocardiography and 6-month angiographic follow up. The primary endpoint was 30-day major adverse cardiac events (MACE) including cardiac death, myocardial infarction, stent thrombosis and repeat target lesion revascularization. The secondary endpoint was device and procedural success. RESULTS: Twenty-nine patients with a mean age of 68.1 ± 12 years were enrolled. The mean VG age (n = 17) was 12.6 years (range 8-19). All patients received heparin, clopidogrel and aspirin, while none received bivalirudin, glycoprotein IIb/IIIa inhibitors (GPIs) or an embolic protection device (EPD). Device and procedural success were 100% and 96.5%, respectively. One patient experienced a procedure-related CPK rise. No MACE were reported at 1 month. CONCLUSION: MGuard-based PCI of NCs and VGs appears encouraging, especially in view of unfavorable patient and lesion characteristics. Both efficacy and safety need to be further established in larger-scale studies with longer follow-up periods.
