About

The purpose of this randomized study is to determine which treatment option, either paclitaxel-eluting balloon, paclitaxel-eluting stent or plain balloon angioplasty is the most effective in the treatment of restenosis after implantation of "Limus"-eluting stents, (LES).

Full description

The use of drug-eluting stents (DES) has led to a drastic reduction of restenosis rates compared to bare metal stents (BMS), but 5% to 10% of patients receiving DES are still in need of revascularization of the treated vessel. Two important families of drugs are used for stent coating: paclitaxel belonging to the taxane family, and the "limus"-family such as sirolimus, everolimus, zotarolimus, biolimus A9 and pimecrolimus.

Data regarding the optimal treatment of in-DES-restenosis is very limited. Implanting a new DES for in-DES-restenosis has been reported to be associated with re-restenosis rates as high as 43%. Several recent well published studies have shown a substantial reduction of restenosis using paclitaxel-eluting balloons (PEB) for de-novo lesions and BMS-restenotic lesions.

The objective of this randomized trial is to assess the hypothesis, that PEB are non-inferior to paclitaxel-eluting-stents (PES) for restenosis in "limus"-eluting-stents (LES), and both, PEB and PES, are superior to plain angioplasty in patients with restenosis after initial LES implantation.
