In order to compare the long-term clinical and angiographic outcomes after sirolimus-eluting stent (SES) and bare-metal stent (BMS) placement in severely calcified lesions using a rotablator under the widespread indication of SES, a nonrandomized examination of 312 consecutive lesions after successful implantation of a BMS (99 lesions in 84 patients; from January 2003) or SES (213 in 167; from September 2004) using a rotablator was conducted. The lesion-based primary endpoints (cardiac death and nonfatal recurrent myocardial infarction) and the secondary endpoint [binary restenosis (BR) (diameter stenosis > 50
