Test Safety of Biodegradable and Permanent Limus-Eluting Stents Assessed by Optical Coherence Tomography
Randomized Comparison of Limus-Eluting Stents With Biodegradable or Permanent Polymer Coating Regarding Stent Coverage Assessed by Optical Coherence Tomography
The objective of the study is to assess the superiority of the biodegradable polymer based limus-eluting stent (Nobori®) compared with the permanent polymer based everolimus-eluting stent (XIENCE V®) regarding absolute percentage of uncovered stent strut segments.
The mid-term efficacy of drug-eluting stents has been well-established, but there is an ongoing debate on the potential of an increased incidence of late stent thrombosis, particularly after discontinuation of thienopyridine therapy, as well as of delayed onset of restenosis or catch-up phenomenon with permanent polymer-based DES. The extent of strut coverage with reduction of exposed thrombogenic material has been shown to be associated with the inflammatory reaction grade and with the incidence of stent thrombosis. The optical coherence tomography (OCT) is an intravascular imaging modality based on light. The principle is similar to intravascular ultrasound, but due to the much shorter wave length of light, it offers a much better resolution up to 10µm, enabling the exact determination of strut coverage, neointimal thickness, vessel size, presence of dissections, and even the presence of inflammation.
