Not Applicable

Completed

• Conditions: Cardiovascular Diseases

• Registration Number: NCT02499692
• Lead Sponsor: Boston Scientific Corporation

Brief Summary

Prospective, multicenter, single-arm study, enroll 100 patients in no more than 10 sites across China, the primary endpoint is Technical success.

Detailed Description

The study is To evaluate clinical and peri-procedural angiographic outcomes for the SYNERGYTM MONORAILTM Everolimus-Eluting Platinum Chromium Coronary Stent System in the treatment of subjects with atherosclerotic lesion(s) ≤34 mm in length (by visual estimate) in native coronary arteries ≥2.25 mm to ≤4.0 mm in diameter (by visual estimate).

4. Planned treatment of more than 3 lesions, Planned treatment of lesions in more than 2 major epicardial vessels, Planned treatment of a single lesion with more than 1 stent
5. Target lesion(s) is located within 3 mm of the origin of the left anterior descending (LAD) coronary artery or left circumflex (LCx) coronary artery by visual estimate.
6. Target vessel develops a dissection greater than National Heart, Lung, Blood Institute (NHLBI) type C following the pre-dilatation/pre-treatment of the first target lesion
