5. 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.
