简要总结

To evaluate the safety and efficacy of the Janus OPTIMA Tacrolimus-Eluting Stent (Optima TES, CID) for the treatment of de novo coronary lesions when associated with short-term (two months) dual antiplatelet (aspirin + clopidogrel) regimen.

详细描述

The present study is a post-market, prospective, international, two-center, single arm study involving 60 patients with single, de novo non-complex coronary lesions.

Enrolled patients will be asked to return for follow-up clinical evaluation at 1, 6, 12 and 24 months. At 3 months there will be an additional follow-up by phone contact.

Furthermore, the first 15 patients should undergo angiographic and OCT follow-up at two months. The remaining 45 patients should undergo angiographic and IVUS follow-up at 8 months.
