Detailed Description:

Background: The optimal treatment of bare metal stent restenosis (implantation of a drug-eluting stent, simple balloon dilatation, CABG) is still not defined. The most used option nowadays is the implantation of a drug-eluting stent (DES). However, this procedure implies application of a double metal layer in the vessel wall, which is linked to delayed healing. Furthermore there might be a higher risk of malapposition of both struts of the bare metal and the newly implanted drug-eluting stents. These phenomenon's might give rise to an increased risk of stent thrombosis in this patient population. Recently, drug-eluting balloons (DEB) were proposed as a new treatment strategy for bare metal stent restenosis. The initial results of this technique look promising.

Aim: To compare healing processes after treatment of BMS ISR with balloon dilatation using DEB versus implantation of DES.

Methods: 50 patients with BMS restenosis (SVG and bifurcation lesions will be excluded) will be randomized into two treatment groups: SeQuent Please drug-eluting balloon dilatation (group I) versus implantation of an everolimus-eluting Xience V stent (group II). At 9 months, a control angiography with OCT pullback of the treated segment is planned.
