Biodegradable stents: an uncertain future
- Klinika kardiologie IKEM, Praha
The introduction of coronary stents in 1986 change the practice of interventional cardiology since its inception in 1977. Furtherdevelopment lead to metallic drug eluting stents (DES) with improving mechanical properties, decreasing strut thickness and introducingdegradable polymer or nonpolymer, abluminal drug coating. Leaving metallic support lifelong have generated interesttowards biodegradable technology. These temporary biodegradable vascular supports, made of polymers or metal alloys with a drugcoating, have the potential to scaffold the artery to allow natural healing, and then biodegrade. The development of this technologyhas been slow, several biodegradable stents have entered into clinical trials. This article will review the status of biodegradable stentswith an analysis of the causes that lead to worse clinical outcomes with uncertain future as compared to metallic stents.
