Among the second-generation non–balloon interventional coronary devices, stent has attained the greatest clinical dominance. This is due largely to its proven efficacy in salvaging failed interventional procedures from acute or threatened closures[ 1 Roubin GS Cannon AD Agrawal SK Macander PJ Dean JS Baxley WA Breland J Intracoronary stenting for acute and threatened closure complicating PTCA.

Therefore, different stents may yield different acute and late outcomes.[ 8 Rogers C Edelman ER Endovascular stent design dictates experimental restenosis and thrombosis.

This stent model was introduced in our catheterization laboratory in May 1996. To the best of our knowledge, there are to date no published results on this stent design. Accordingly, in this brief report, we analyzed our early experience with, and the early and midterm outcome of, this stent design.
