    2. Intracoronary Imaging

      Intracoronary Imaging
      Two intracoronary imaging techniques are routinely available to complement angiography in the management of coronary artery disease, namely intravascular ultrasound (IVUS) and optical coherence tomography (OCT). The former has been in clinical use for 25 years and has directly informed the fundamentals of atherosclerotic plaque composition and arterial remodelling, as well as contemporary optimal stent implantation technique. 1 , 2 The latter, introduced 10 years ago, has only been more widely ...

    7. Time-related changes in neointimal tissue coverage of a novel Sirolimus eluting stent: Serial observations with optical coherence tomography

      Time-related changes in neointimal tissue coverage of a novel Sirolimus eluting stent: Serial observations with optical coherence tomography
      Background DES has reduced rates of restenosis compared with BMS but it has been associated with delayed healing and increase of stent thrombosis. The aim of our study was to evaluate the vascular time-related changes following implantation of a new SES coated with an amorphous silicon carbide that allows faster re-endothelisation (Orsiro-Biotronik). Methods This prospective registry enrolled STEMI-patients with multi-vessel disease, thus candidates for a two-step procedure. PCI of the ...

    8. OCT imaging of aorto-coronary vein graft pathology modified by external stenting: 1-year post-surgery

      OCT imaging of aorto-coronary vein graft pathology modified by external stenting: 1-year post-surgery
      Aims The Venous External Support Trial (VEST) evaluated whether a novel external stent attenuated saphenous vein graft (SVG) disease assessed with intravascular ultrasound 1 year following coronary artery bypass graft (CABG) surgery. This sub-study assessed SVGs with and without external stenting using optical coherence tomography (OCT). The aim of this study was to accurately compare quantitative and qualitative features of SVGs with and without a novel external stent using OCT ...

    9. Comparative analysis method of permanent metallic stents (XIENCE) and bioresorbable poly-L-lactic (PLLA) scaffolds (Absorb) on optical coherence tomography at baseline and follow-up

      Comparative analysis method of permanent metallic stents (XIENCE) and bioresorbable poly-L-lactic (PLLA) scaffolds (Absorb) on optical coherence tomography at baseline and follow-up
      Aims: Fully bioresorbable Absorb poly-L-lactic-acid (PLLA) scaffolds (Abbott Vascular, Santa Clara, CA, USA) are a novel approach for the treatment of coronary narrowing. Due to the translucency of the material (PLLA), the optical coherence tomography (OCT) measurement methods used in the ABSORB trials were unique but not applicable for permanent metallic stents. When the Absorb scaffold and metallic stents are compared in the context of randomised trials, it is challenging ...

    10. Is high pressure postdilation safe in bioresorbable vascular scaffolds? Optical coherence tomography observations after noncompliant balloons inflated at more than 24 atmospheres

      Is high pressure postdilation safe in bioresorbable vascular scaffolds? Optical coherence tomography observations after noncompliant balloons inflated at more than 24 atmospheres
      Objectives Optical coherence tomography (OCT) was used to investigate integrity and expansion of bioresorbable drug-eluting scaffolds (BVS) after high-pressure postdilation (HPPD). Background Because of concerns about the risk of BVS damage, postdilation was not recommended and applied in the existing randomized studies and most registries. Recent real world data suggest incomplete BVS expansion cause higher rates of thrombosis. In vivo confirmation of the safety of high pressure postdilation is of ...

    11. Inducing Persistent Flow Disturbances Accelerates Atherogenesis and Promotes Thin Cap Fibroatheroma Development in D374Y-PCSK9 Hypercholesterolemic Minipigs

      Inducing Persistent Flow Disturbances Accelerates Atherogenesis and Promotes Thin Cap Fibroatheroma Development in D374Y-PCSK9 Hypercholesterolemic Minipigs
      Background Although disturbed flow is thought to play a central role in the development of advanced coronary atherosclerotic plaques, no causal relationship has been established. We evaluated whether inducing disturbed flow would cause the development of advanced coronary plaques, including thin cap fibroatheroma. Methods and Results D374Y -PCSK9 hypercholesterolemic minipigs (n=5) were instrumented with an intracoronary shear-modifying stent (SMS). Frequency-domain optical coherence tomography was obtained at baseline, immediately poststent ...

    12. Bioresorbable vascular scaffold overlap evaluation with optical coherence tomography after implantation with or without enhanced stent visualization system (WOLFIE study): a two-centre prospective comparison

      Bioresorbable vascular scaffold overlap evaluation with optical coherence tomography after implantation with or without enhanced stent visualization system (WOLFIE study): a two-centre prospective comparison
      To assess if enhanced stent visualization (ESV)-guided implantation of overlapping bioresorbable vascular scaffold (BVS) is superior to angiography alone-guided implantation in the reduction of overlap length. WOLFIE is a two-centre prospective open study enrolling 30 patients treated with implantation of at least two overlapping BVS. In the first centre (London), BVS implantation was guided by conventional angiography, while in the second centre (Ferrara), an ESV system was systematically employed ...

    13. Optical coherence tomography appraisal of residual thrombus burden in patients with ST-segment elevation myocardial infarction undergoing intraprocedural versus post-stenting prolonged bivalirudin infusion. Rationale and design of the MATRIX (Minimizing A

      Optical coherence tomography appraisal of residual thrombus burden in patients with ST-segment elevation myocardial infarction undergoing intraprocedural versus post-stenting prolonged bivalirudin infusion. Rationale and design of the MATRIX (Minimizing A
      Aims: Residual thrombus accumulation around stent struts has been observed after the end of primary PCI and may represent a risk factor for acute stent thrombosis. The aim of this study is to test whether a strategy of prolonged bivalirudin infusion may reduce thrombosis of stent struts as compared to an intraprocedural only administration in subjects undergoing primary PCI. Methods and results: One hundred and sixty patients will be selected ...

    14. Optical Coherence Tomography Evaluation of Overlapping Everolimus-Eluting Bioresorbable Vascular Scaffolds implantation guided by Enhanced Stent Visualization System

      Optical Coherence Tomography Evaluation of Overlapping Everolimus-Eluting Bioresorbable Vascular Scaffolds implantation guided by Enhanced Stent Visualization System
      In a porcine model, implantation of overlapping everolimus-eluting bioresorbable vascular scaffolds (BVS, Abbott Vascular, Santa Clara, California) resulted in delayed struts coverage and higher neointimal response [1] that might lead to important clinical consequences (scaffold thrombosis; in-scaffold restenosis). According to this, any effort to minimize BVS overlap area and the number of overlapping struts is desirable. A bench testing in an in vitro phantom model has shown how to minimize ...
