The aim of this prospective, randomized study is to compare the efficacy and safety of biodegradable polymer based limus-eluting stents (BPDES) with permanent polymer based everolimus eluting stents (PPDES).
Restenosis affects 20-40% of de novo coronary lesions treated with bare-metal stents. Although it is often considered a benign process, recent data indicate that in-stent restenosis has a negative impact on long-term survival of patients treated with coronary stents. Drug eluting stents have emerged as the most effective strategy for the prevention of restenosis. A large number of studies showed that drug-eluting stents significantly reduce in-stent restenosis and the subsequent need for target vessel revascularisation compared with bare-metal stents. Available evidence shows that all 3 limus drugs − rapamycin, everolimus and biolimus − are very effective in suppressing neointima formation after coronary stenting. Drugs are fully released within a few weeks from the majority of current DES. However, most of the DES use permanent polymers, which continue to remain in the vessel wall even after accomplishing their drug-release mission. Their permanent presence may be associated with persistent inflammatory reaction and delayed neointimal proliferation and vessel thrombosis. Clinical trial evidence with biodegradable polymer DES is still limited, but there are great expectations that this DES technology might be the dominant one in the years to come.

Stents that are covered with materials that are embedded with chemicals that are gradually released into the surrounding milieu.
Strongly cationic polymer that binds to certain proteins; used as a marker in immunology, to precipitate and purify enzymes and lipids. Synonyms: aziridine polymer; Epamine; Epomine; ethylenimine polymer; Montrek; PEI; Polymin(e).
A polymer obtained by reacting polyacrylic acid with a special anion-leachable glass (alumino-silicate). The resulting cement is more durable and tougher than others in that the materials comprising the polymer backbone do not leach out.
A polyester used for absorbable sutures & surgical mesh, especially in ophthalmic surgery. 2-Hydroxy-propanoic acid polymer with polymerized hydroxyacetic acid, which forms 3,6-dimethyl-1,4-dioxane-dione polymer with 1,4-dioxane-2,5-dione copolymer of molecular weight about 80,000 daltons.
Devices that provide support for tubular structures that are being anastomosed or for body cavities during skin grafting.
A stent is a small mesh tube that's used to treat narrow or weak arteries. Arteries are blood vessels that carry blood away from your heart to other parts of your body. A stent is placed in an artery as part of a procedure called angioplasty. &...
