About this trial
This is an interventional treatment trial for Coronary Artery Stenosis focused on measuring PCI, bioabsorbable scaffold
Eligibility Criteria
Inclusion Criteria:
- patients undergoing percutaneous coronary intervention (PCI)
- lesion no more than 25 mm in length with a reference-vessel diameter of 2.5 to 3.75 mm on visual assessment
Exclusion Criteria:
- patients with acurate myocardial infarction (STEMI)
- patients with specific complex lesion features (left main, aorto ostial, bifurcation with side branch ≥ 2 mm in diameter, extreme angulation proximal or within the target lesion, moderate or heavy calcification proximal or within the target lesion, chronic total occlusion)

Outcomes
Primary Outcome Measures
Minimal lumen area (MLA) in the BVS (mm2)
After BVS implantation, optical coherence tomography is used to measure MLA in the scaffold area.
Secondary Outcome Measures
Clinically - driven target vessel revascularization
Patient is followed after BVS implantation in 1,6 and 12 months in the outpatient department.
Eccentricity index
After BVS implantation, optical coherence tomography is used to measure MLA in the scaffold area. Eccentricity index is calculated as minimal luminal diameter divided by maximal luminal diameter in the MLA segment.
Expansion index
After BVS implantation, optical coherence tomography is used to measure MLA in the scaffold area. Expansion index is calculated as minimal luminal diameter divided by maximal expected diameter of the non-compliant balloon used for high pressure postdilatation.

5. Study Description
Brief Summary
The purpose of this study is to determine the optimal way of predilatation for BVS implantation.
Detailed Description
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).
