ABSTRACT
Treatment of in-stent restenosis lesions, especially calcified lesions, with stent underexpansion, generally requires more complex techniques, such as rotational atherectomy. The case reported is a male patient with a 99% in-stent focal restenosis lesion at the origin of the first diagonal branch, where two stents were implanted 14 years ago. After failure of balloon angioplasty alone, ablation of the plaque and part of the stent struts was performed using the rotational atherectomy technique, which allowed the implantation of a new stent which was totally expanded.
