The purpose of this study is to determine the optimal way of predilatation for BVS implantation.
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).
Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Counterpulsation in which a pumping unit synchronized with the patient's electrocardiogram rapidly fills a balloon in the aorta with helium or carbon dioxide in early diastole and evacuates the balloon at the onset of systole. As the balloon inflates, it raises aortic diastolic pressure, and as it deflates, it lowers aortic systolic pressure. The result is a decrease in left ventricular work and increased myocardial and peripheral perfusion.
Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1, laser fiber delivering the energy while the inflated balloon centers the fiber and occludes the blood flow; 2, balloon angioplasty immediately following laser angioplasty; or 3, laser energy transmitted through angioplasty balloons that contain an internal fiber.
