 The case of a 58-year-old woman with old myocardial infarction is described. She developed acute myocardial infarction in August, 2003. An emergency coronary arteriogram revealed total occlusion of the proximal right coronary artery. Reperfusion was achieved by bare metal stent implantation with a distal protection device. As a coronary angiogram 3 months and 10 months after the onset showed diffuse in-stent restenosis(ISR), the ISR was treated with gradually prolonged inflation balloon angioplasty and by using a perfusion balloon catheter,respectively. However, as a coronary angiogram 3 months after the second follow-up revealed diffuse ISR, the recurrent ISR was treated with CypherTM stents implantation. At twelve months follow-up after CypherTM stent implantation, the coronary angiogram showed no in-stent restenosis. However, three months later, a coronary angiogram showed 75% in-stent restenosis at the distal site of CypherTM stent. This is a case report of a late in-stent restenosis after 14 months of sirolimus eluting stent implantation. Further studies should investigate the clinical relevance of this phenomenon and the appropriate length of follow-up needed in patients who receive sirolimus eluting stents.
