An 88-year-old woman underwent emergency percutaneous coronary intervention (PCI) to treat circulatory collapse with severe stenosis in the distal left main coronary artery (LMCA). After 3.5/18-mm stent deployment from the LMCA to the left anterior descending artery (LAD), coronary perforation occurred in the LAD ostium. Therefore, we implanted a polytetrafluoroethylene (PTFE)-covered stent crossing over the left circumflex artery (LCX), and achieved successful hemostasis. Additional PCI was undertaken to recanalize the LCX. A Confienza 8-20 guidewire was able to penetrate the wall of the PTFE-covered stent, and coronary flow was successfully recovered after deployment of a 2.5/8-mm stent in the proximal LCX.
