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 (ANCHOR)

April 17, 2012 updated by: Myeong-Ki Hong, Yonsei University

2-phased Randomized Comparison Between PromusTMElementTM Versus Xience PRIME® Stent

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.
