xience v everolimus eluting coronary stent system (eecss) china: post-approval randomized control trial (rct)

Conditions: Coronary Occlusion; Thrombosis (Stent Thrombosis); Vascular Disease; Myocardial Ischemia; Coronary Artery Stenosis; Coronary Disease; Coronary Artery Disease; Coronary Restenosis

Summary: this is a prospective, randomized, active-controlled, open label, parallel two-arm, multi-center, post-approval study descriptively comparing the xience v eecss to the cypher select plus sirolimus-eluting coronary stent system (secss) ("cypher select plus") during commercial use in china.

objectives * confirm the safety and effectiveness of the xience v eecss for the treatment of patients in china * evaluate patient compliance with dual antiplatelet therapy (dapt) * evaluate physician-determined xience v eecss acute performance, deliverability, and resource utilization
