title: A case of coronary rupture and pseudoaneurysm formation after fracture of implanted paclitaxel-eluting stents.
abstract: A 48-year-old man who had undergone implantation of two paclitaxel-eluting stents (PESs) at the right coronary artery was admitted to our hospital with progressive dyspnea. In the coronary care unit, he developed cardiogenic shock due to cardiac tamponade treated by pericardiocentesis. A coronary angiogram showed a large pseudoaneurysm at the site of the previously implanted stents, suggesting coronary rupture due to implanted stent fracture. The pseudoaneurysm was completely sealed by polytetrafluoroethylene-covered stent implantation. Although this case is very rare, coronary rupture by stent fracture should be considered when cardiac tamponade occurs after drug-eluting stent implantation, especially PES.
