Abstract

This study examined the outcomes of patients who underwent sirolimus‐eluting stent (SES) implantation for the treatment of heavily calcified coronary lesions (HCCL) with and without the use of rotational atherectomy (rotablator). We investigated 150 consecutive patients with angiographic evidence of HCCL who underwent SES implantation. Sixty‐nine patients underwent SES implantation without the need of rotablator (SES), and 81 patients required rotational atherectomy to modify the plaque and facilitate the delivery of the stent (SES + rotational atherectomy). Clinical success was equivalent in both groups (>98%) and there were no in‐hospital outcome differences. At 6 months, the target lesion revascularization rate was 4.9% in SES vs. 4.2% in SES + rotational atherectomy groups, respectively (P = NS). Mortality at 6 months was 7.9% in the SES group vs. 6.8% in the SES + rotational atherectomy group (P = NS). SES performs well in patients with complex HCCL, with a relative low event rate. Lesions requiring rotational atherectomy to facilitate dilation and stenting had similar outcomes after SES implantation to those that could be stented without the need for rotablator. © 2006 Wiley‐Liss, Inc.
