title: Primary stenting of occluded native coronary arteries II--rationale and design of the PRISON II study: a randomized comparison of bare metal stent implantation with sirolimus-eluting stent implantation for the treatment of chronic total coronary occlusions.
abstract: Primary intracoronary stent placement after successfully crossing chronic total occlusions (CTO) decreases the high restenosis rate at long-term follow-up compared with conventional balloon angioplasty. Several studies have shown the efficacy of sirolimus-eluting stents in selected groups of patients. Whether sirolimus-eluting stents are superior to bare metal stents in CTO is unknown. In this prospective randomized trial, bare metal stent implantation will be compared with sirolimus-eluting stent implantation for the treatment of CTO. A total of 200 patients will be followed up for 12 months with angiographic follow-up at 6 months. Quantitative coronary analysis will be performed by an independent core laboratory. The primary end point is the binary angiographic restenosis and reocclusion rate.
