Outcomes
Primary Outcome Measures
Stent expansion index (SEI)
Stent expansion index (SEI), defined as minimum stent area divided by mean reference area in an optical coherence tomography (OCT) quantitative analysis
Secondary Outcome Measures
Angiographic Success
'Angiographic Success', defined as the achievement of residual angiographic stenosis <30% of the target lesion in the presence of TIMI 3 flow

5. Study Description
Brief Summary
The objective of this prospective, multicenter, randomized, open-label trial is to evaluate the completeness of stent expansion following a strategy of lesion preparation with either a Super High-Pressure NC PTCA Balloon (OPN NC) or a Scoring PTCA Balloon (NSE Alpha) after unsuccessful lesion preparation with conventional NC balloon angioplasty in an angiographically well-defined group of patients with severely calcified coronary lesions (grade 3) undergoing coronary stent implantation (SYNERGY everolimus-eluting stent (EES)).
