Use of rotational atherectomy for treatment of in-stent restenosis with coronary double-mesh stent underexpansion. Case report

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