Successful sealing of a coronary artery perforation with a mesh-covered stent.

Coronary artery perforation is a rare, but particularly feared and sometimes life-threatening, complication of percutaneous coronary interventions. The incidence of coronary perforation has increased with newer, more invasive interventional devices and techniques like rotablation, excimer laser coronary angioplasty, routine high-pressure balloon dilatation, or chronic total occlusion interventions. Here we describe a case of Ellis grade 2 perforation following a balloon dilatation performed in an in-stent restenotic total occlusion. The perforation was successfully sealed with a recently introduced device, a mesh covered stent (MGuard stent, Inspire MD). This new stent is much more flexible than the polytetrafluoroethylene-covered stent, which is often implanted in Ellis 2 or 3 grade perforations.
