The Investigators will test the hypothesis that MGuard net protective stent, the investigational device, would be superior to conventional revascularization strategy (i.e. bare-metal stenting plus manual thrombectomy), for STEMI patients undergoing urgent percutaneous coronary interventions.
Embolization of thrombotic debris still represents a complication for ST-elevation myocardial infarction (STEMI) patients undergoing percutaneous coronary interventions (PCI).
Distal embolization may decrease coronary and myocardial reperfusion after PCI in STEMI setting.
Unfortunately, intracoronary filters present several important limitations limiting their use and their efficacy especially in presence of huge amount of thrombus. In this respect, recent trials investigated whether a default manual thrombectomy strategy before stenting would ameliorate angiographic as well as clinical outcomes for STEMI patients undergoing percutaneous revascularization.
Of note, the most of embolization occurs when guidewire, and thrombectomy device cross the thrombus, and after the stent has been implanted as a consequence of plaque prolapse through the stent struts.
MGuard net protective stent, the investigational device, is a bare-metal stent covered with a ultra-thin flexible polyethylene terephthalate (or Dacron) mesh sleeve, that is anchored to the external surface of the struts. This biocompatible fiber net (string diameter 10-22 μm) has minimal effects on the stents' trackability and deliverability. During stent deployment, the net stretches and slides over the expanding stent struts, trapping the thromboembolic debris underneath the fiber net and isolating the prothrombotic intima components from the blood stream.
This protocol will test the hypothesis that MGuard stent would be superior to conventional revascularization strategy (i.e. bare-metal stenting plus manual thrombectomy), for STEMI patients undergoing urgent PCI in terms of angiographic as well as clinical outcomes.

A stent is a small mesh tube that's used to treat narrow or weak arteries. Arteries are blood vessels that carry blood away from your heart to other parts of your body. A stent is placed in an artery as part of a procedure called angioplasty. &...
