Comparison of clinical and angiographic outcome of sirolimus-eluting stent implantation versus cutting balloon angioplasty for coronary in-stent restenosis.

Sixty in-stent restenotic lesions were treated with sirolimus-eluting stent implantation and retrospectively compared with a group of matched lesions treated with cutting balloon angioplasty. The results indicate a good safety profile of the procedure and a 57% reduction in the incidence of recurrent restenosis in comparison with cutting balloon angioplasty.
