The MGuard coronary stent: safety, efficacy, and clinical utility

Montserrat Gracida et al. Vasc Health Risk Manag. .

Abstract

Atheromatous and thrombotic embolization during percutaneous coronary revascularization is a feared complication that may cause impaired myocardial reperfusion even with a patent epicardial vessel. The MGuard stent is a cobalt chromium bare metal stent with a porous net attached to its outer surface that has been designed to prevent thrombus fragmentation and distal embolization during stent implantation. This review summarizes the available evidence supporting the use of the MGuard stent in different scenarios such as lesions with high thrombus burden, saphenous vein graft interventions, coronary perforations, or carotid lesions.

Keywords: Coronary artery disease; complication; coronary stent; myocardial infarction; no-reflow phenomenon; thrombus.

Coronary angiogram (30° cranial oblique projection) showing a totally occluded right coronary artery before intervention (A). Despite exhaustive thrombus aspiration. Red arrow points to the thrombotic total occlusion. (B), a high thrombus burden (TIMI thrombus score =4) persisted at the bifurcation (red arrows). After MGuard deployment (green line), TIMI 3 flow was restored to the posterolateral branch, although the posterior descending artery persisted totally occluded (C). Following “reverse T stenting,” final TIMI flow was 3 in both the posterior descending artery and the posterolateral branch branches (D, final result). Abbreviation: TIMI, thrombolysis in myocardial infarction.
