ANCHOR: Assessment of Stent Malapposition and Neointimal Coverage on Optical coHerence Tomography at Post-procedure and 3 Months After Platinum Chromium Alloy Of the Element™ Stent Implantation
Study Details
Study Description
Brief Summary
The purpose of this study is to compare the degree of stent malapposition on an immediate optical coherence tomography (OCT) after nominal stent pressure and at a final post-procedure OCT (ANCHOR-I) and the neointimal coverage on 3-months OCT following the intervention with the randomly assigned two drug-eluting stents (DES), PromusTMElementTM stents versus Xience PRIME® stents.

Outcome Measures
Primary Outcome Measures
- the ratio of the malapposed strut [Participants will be followed from first OCT invervention to 3month OCT following intervention]
The ratio of the malapposed strut, on an immediate OCT after nominal stent pressure and at a final post-procedure between two different DES; ANCHOR-I
Secondary Outcome Measures
- Incidence of stent malapposition [3months OCT following intervention]
- Neointimal coverage(ANCHOR II) [3 month-OCT after stent implantation]
- Incidence of plaque prolapse [final postprocedural OCT]
- Evaluation of stent expansion [an immediate and post-procedural OCT]
- Stent malapposition [on 3 month OCT intervention]
