Brief Summary:

This is a prospective, multi-center registry to evaluate safety and effectiveness of the Everolimus Drug Eluting Stent for treatment coronary revascularization in Chinese patients with long lesion, small vessel or multi-vessel diseases.

Condition or disease	Intervention/treatment	Phase
Coronary Artery Diseases	Procedure: Everolimus Drug Eluting Stent; Drug: Aspirin; Drug: Clopidogrel; Drug: Heparin or Bivalirudin	Phase 4

Detailed Description:

Study Device:The XIENCE V® Everolimus Eluting Coronary Stent System (XIENCE V EECSS or XIENCE V stent system) is a device/drug combination product consisting of either the MULTI-LINK VISION® Coronary Stent System or the MULTI-LINK MINI VISION® Coronary Stent System coated with a formulation containing everolimus, the active ingredient, embedded in a non-erodible polymer. Design:A prospective, multi-center, registry that is designed to enroll Chinese patients with either Long Lesion, or Small Vessel or Multi-Vessel diseases. Purpose:To evaluate the safety and effectiveness of the XIENCE V® everolimus drug eluting stent for coronary revascularization of patients with either long lesion, or small vessel, or multi-vessel diseases. Enrollment:Approximately 1900 patients will be enrolled in at least 45 but up to 51 centers. Mainland China 41 up to 47 centers, Taiwan China 3 centers and Macao China 1 center. This registry is planned to enroll at least 50% of patients with multi-vessel disease. Primary Endpoint:Ischemia-driven Target Vessel Failure (TVF) which is a composite of cardiac death, myocardial infarction (Q and non-Q wave) and target vessel revascularization (TVR) at 12 months post-index procedure. Follow-Up Visits:30 days, 6 months, 12 months, and 24 months post index procedure.
