PROMUS Element Japan Small Vessel Trial
1. března 2016 aktualizováno: Boston Scientific Corporation
A Prospective Multicenter Trial to Assess an Everolimus-Eluting Coronary Stent System (PROMUS Element™) for the Treatment of a Small Vessel De Novo Coronary Artery Lesion in Japan
A non-randomized, small vessel (SV) trial at approximately 15 sites in Japan to enroll 60 patients with a de novo lesion ≤28 mm in length (by visual estimate) in a native coronary artery ≥2.25 mm to <2.50 mm in diameter (by visual estimate).
Approximately thirty patients will be randomly assigned to the angiographic subset to also undergo angiographic assessment after the 12-month clinical follow-up.
