Brief summary
The PROMUS Element Long Lesion clinical trial –PLATINUM LL, is a prospective, multi-centre trial to evaluate the safety and effectiveness of the PROMUS Element Everolimus-Eluting Coronary Stent System in patients with a lesion that is 24-34mm in length. Treatment will be in participants with a single de novo (new or untreated) atherosclerotic coronary artery lesion. A separate coronary artery (de novo) narrowing is able to be treated with a commercial treatment (eg: stent such as PROMUS, balloon angioplasty, excluding brachytherapy) during the initial procedure. Up to 35 sites enrolling up to 102 patients. Follow up at 30 days, 6 and 12 months after intervention.
Interventions
The Everolimus-Eluting Coronary Stent System (PROMUS Element) is a metal tube coated with the drug Everolimus. One stent will be permanently implanted in the patient via use of a catheter inserted into the vasculature. The drug dosage depends on the size of the stent and varies from 57 micrograms (2.25x12mm stent) to 242 micrograms (4.0x38mm stent) and this drug is gradually released into the surrounding arterial tissue for approximately 3 months following stent implantation. Stent size is selected by the investigator based on vessel diameter and length. Typically stent diameter is selected to be slightly larger than the vessel diameter (ie a 3.0mm stent would be used to treat a 2.8mm vessel). Typically stent length is selected so that the stent is 2-4mm longer than the lesion length (ie a 28mm stent would be used to treat a 22mm lesion)
