Left main coronary artery stenosis is associated with dismal prognosis when untreated. Coronary artery bypass grafting (CABG) is the standard treatment. Although stent implantation is increasingly performed for de novo left main lesion, CABG is inevitable if in-stent restenosis (ISR) occurs. Recently, use of sirolimus eluting stents has proved effective in reducing restenosis in simple de novo lesions. Authors present a patient who underwent sirolimus eluting stent implantation for significant left main ISR involving the bifurcation. The patient was a 60 year old woman who presented with exertional angina caused by isolated ostial left anterior descending artery stenosis. Direct bare stent implantation was initially performed, but was followed by occurrence of diffuse ISR six months later.
