Abstract
The BARASTER registry was formed to evaluate the initial success and long‐term results of rotational atherectomy in the management of in‐stent restenosis. Rotational atherectomy was used in 197 cases of in‐stent restenosis: 46 with stand‐alone rotational atherectomy or at most 1 atmosphere of balloon inflation (Rota strategy), and 151 with rotational atherectomy and adjunctive balloon angioplasty P = 0.08). There was a reduction in one year clinical outcomes (death, myocardial infarction or target lesion revascularization) in the combination group (38% vs. 60% with Rota and 52% with balloons, P = 0.02). These data support a benefit of the strategy of debulking with rotational atherectomy followed by adjunctive balloon angioplasty, in the management of in‐stent restenosis. Cathet. Cardiovasc. Intervent. 51:407–413, 2000.
