Randomized Controlled Trial Multicenter Study
Primary Stenting of Totally Occluded Native Coronary Arteries II (PRISON II): a randomized comparison of bare metal stent implantation with sirolimus-eluting stent implantation for the treatment of total coronary occlusions.
Sirolimus-eluting stents markedly reduce the risk of restenosis compared with bare metal stents. However, it is not known whether there are differences in effectiveness between bare metal and sirolimus-eluting stents in patients with total coronary occlusions. ⋯ In patients with total coronary occlusions, use of the sirolimus-eluting stents are superior to the bare metal stents with significant reduction in angiographic binary restenosis, resulting in significantly less need for target lesion and target vessel revascularization.
