Conditions

Coronary Artery Disease, Drug-eluting Stents

Brief summary

Durable polymer was considered to be the cause of a chronic inflammatory response that leadas to impaired endothelialization of the stent strut and subsequently increases the risk of stent thrombosis. Ultimaster stent (Ultimaster, Terumo Corporation, Tokyo, Japan) are thin strut, silorimus-eluting, biodegradable copolymer to completely degrade over 3-4 months.

Detailed description

Drug-eluting stents (DES) significantly improved outcome compared wiht bare-metal stents because of slow-elution of the antiproliferative drug mixed with a polymer coated on the stent surface. However, the polymers used in the first-generation DES were considered to be the cause of a chronic inflammatory response that leadas to impaired endothelialization of the stent strut and subsequently increases the risk of stent thrombosis. One strategy to mitigate this problem is a biodegradable polymer, which dissolves over time and leaves only the metalic struts behind. Ultimaster stent are silorimus-eluting, biodegradable poly DL-lactide-co-caprolactone copolymer (PDLLA+PCL) to completely degrade over 3-4 months and is also made of 80μm thin strut. The aim of the current study is to investigate the efficacy and safety outcomes in patients treated with ultimaster stents in real-world.
