      Complex bifurcation lesions: Randomized comparison of a fully bioresorbable modified t stenting strategy versus bifurcation reconstruction with a dedicated self-expanding stent in combination with bioresorbable scaffolds, an OCT study: Rationale and desig
      Objective There is an ongoing controversy regarding the efficacy and safety of different percutaneous stenting techniques for coronary bifurcation lesions needing 1 stent. The promise of safe vessel restoration with bioresorbable scaffolds (BRS) may not be transferable to complex double BRS bifurcation techniques, and permanent metallic scaffolding of the bifurcation core may be needed. We identified modified-T stenting as the most promising fully bioresorbable 2-stent strategy in a preclinical setting ...

    7. Optical coherence tomography-based assessment of bifurcation stenting using the Axxess™ Biolimus A9™-eluting stent system

      Optical coherence tomography-based assessment of bifurcation stenting using the Axxess™ Biolimus A9™-eluting stent system
      Bifurcation lesions are associated with increased procedural complications and worse long-term outcome. Multiple techniques are available, including the dedicated drug-eluting Axxess stent system (Biosensors International Ltd., Singapore, Singapore), providing complete bifurcation support without covering the carina. Low rates of restenosis in both main vessel (MV) and side branch (SB) have been demonstrated. High-resolution imaging techniques such as intravascular optical coherence tomography (IV-OCT) may help the positioning and implantation of the ...

      Feature Of The Week 10/18/2015: Characterising Kiwifruit (Actinidia sp.) Near Skin Cellular Structures using Optical Coherence Tomography
      Pre-harvest growing conditions during the development of fruit have impacts on fruit quality at the time of harvest and during storage. These impacts may result in differences in the skin properties of the fruit and some sub-surface cellular structural changes, which have potential effects on postharvest fruit quality and storability. Optical coherence tomography (OCT) is a non-destructive imaging method that enables acquisition of three-dimensional (3D) images of sub-surface structures of ...

    11. OCT for bifurcation stenting: what have we learned?

      OCT for bifurcation stenting: what have we learned?
      Treatment of bifurcation lesions by percutaneous coronary intervention (PCI) shows major variation in complexity. Intravascular optical coherence tomography (OCT) provides high-resolution images of the pathoanatomy, thrombus, wires and stent positions during the procedure. This information may prove crucial in optimising PCI results and clinical outcomes after complex bifurcation treatment. Mounting evidence confirms the feasibility of OCT in bifurcations, and specific steps where OCT may be advantageous in guiding bifurcation PCI ...
