Randomized, single-center study. Forty-five patients with intended BVS implantation will be randomized in ratio of 1:1:1 to different predilatation strategies(non-compliant balloon/Emerge NC™, Boston Scientific, cutting balloon/Flexitome™, scoring balloon/Scoroflex™,Orbus). Predilatation is intended to be done in a vessel:balloon ratio of 1:1. If the device is not able enter the lesion, it will be replaced with a conventional semicompliant balloon with the same predilatation strategy (a vessel:balloon ratio of 1:1) After a successful predilatation, the BVS (Absorb™, Abbott) will be implanted and this procedure will be accomplished by a high pressure postdilatation with a non-compliant balloon (Emerge NC™, BSCI). The MLA of the Absorb stent will be evaluated with optical coherence tomography (OPTIS, St.Jude).
The purpose of this study is to determine the optimal way of predilatation for BVS implantation.
