While polytetrafluoroethylene (PTFE)-covered stents (JOMED International Company, Sweden) have been used for many types of coronary intervention, reports of PTFE-covered stents for aorto-ostial in-stent restenosis are very rare. We report three cases treated at our center for in-stent restenosis of the right coronary ostium using PTFE-covered stent implants. However, the long-term results were not as expected. Neointimal proliferation at the edges of the stents remains a problem in PTFE-covered stent implantation. The efficacy of the PTFE-covered stent for the treatment of in-stent restenosis, especially of the ostium, remains to be elucidated by further studies.
