    2. Feasibility of a porcine arteriovenous shunt model for assessment of acute thrombogenicity in bifurcation stenting technique by optical coherence tomography

      Feasibility of a porcine arteriovenous shunt model for assessment of acute thrombogenicity in bifurcation stenting technique by optical coherence tomography
      Background Double kissing (DK) crush stenting has been reported as a superior bifurcation stenting strategy compared to culotte stenting. However, the mechanism associated with the reduction of clinical events by DK crush stenting remains unclear. We therefore investigated the thrombogenicity of DK crush stenting and culotte stenting with both bare-metal stents (BMS) and drug-eluting stents (DES) and the feasibility of a novel porcine arteriovenous shunt model. Methods High-resolution intracoronary imaging ...

    3. Serial 3-Dimensional Optical Coherence Tomography Assessment of Jailed Side-Branch by Second-Generation Drug-Eluting Absorbable Metal Scaffold (From the BIOSOLVE-II Trial)

      Serial 3-Dimensional Optical Coherence Tomography Assessment of Jailed Side-Branch by Second-Generation Drug-Eluting Absorbable Metal Scaffold (From the BIOSOLVE-II Trial)
      Second-generation drug-eluting absorbable metal scaffold (DREAMS 2G) is used for treating coronary lesions. However, the natural history of the jailed side-branch (SB) after DREAMS 2G implantation remains to be elucidated. The aim of this study is to investigate the effect of scaffold struts on jailed SBs as assessed by 3-dimensional (3D) optical coherence tomography (OCT) after implantation of DREAMS 2G. We enrolled the patients who received a DREAMS 2G implantation ...

    4. Impact of procedural characteristics on coronary vessel wall healing following implantation of second-generation drug-eluting absorbable metal scaffold in patients with de novo coronary artery lesions: an optical coherence tomography analysis

      Impact of procedural characteristics on coronary vessel wall healing following implantation of second-generation drug-eluting absorbable metal scaffold in patients with de novo coronary artery lesions: an optical coherence tomography analysis
      Aims Second-generation drug-eluting absorbable metal scaffold (DREAMS 2G) is an alternative novel device for treating coronary lesions. However, the relationship between in-scaffold dimensions after implantation of DREAMS 2G and vessel healing and luminal results at follow-up is unknown. The aim of this study is, therefore, to investigate whether the expansion index after implantation of DREAMS 2G as assessed by optical coherence tomography (OCT) impacts late luminal status and healing of ...

    5. Serial 2-Dimensional and 3-Dimensional Optical Coherence Tomography Assessment of Overhanging Struts of Drug-Eluting Absorbable Metal Scaffold

      Serial 2-Dimensional and 3-Dimensional Optical Coherence Tomography Assessment of Overhanging Struts of Drug-Eluting Absorbable Metal Scaffold
      A 75-year-old woman with stable angina pectoris underwent percutaneous coronary intervention of the left anterior descending coronary artery, whereby a 3.25/16-mm paclitaxel-eluting absorbable metal scaffold (DREAMS, Biotronik, Blach, Switzerland) was successfully implanted. Post-procedural angiography showed excellent results without pinching of the side branch ostium. The patient experienced no procedure-related complications, and was discharged 48 h after the procedure on dual antiplatelet therapy. Optical coherence tomography (OCT) (LightLab Imaging ...

    6. Intra-Stent Tissue Evaluation within Bare Metal and Drug-Eluting Stents > 3 Years since Implantation in Patients with Mild to Moderate Neointimal Proliferation Using Optical Coherence Tomography and Virtual Histology Intravascular Ultrasound

      Intra-Stent Tissue Evaluation within Bare Metal and Drug-Eluting Stents > 3 Years since Implantation in Patients with Mild to Moderate Neointimal Proliferation Using Optical Coherence Tomography and Virtual Histology Intravascular Ultrasound
      Objective: We aimed to compare neointimal tissue characteristics between bare-metal stents (BMS) and drug-eluting stents (DES) at long-term follow-up using optical coherence tomography (OCT) and virtual histology intravascular ultrasound (VH-IVUS). Background: Neoatherosclerosis in neointima has been reported in BMS and in DES. Methods: Thirty patients with 36 stented lesions [BMS (n = 17) or DES (n = 19)] 3 years after implantation were prospectively enrolled. OCT and VH-IVUS were performed and analyzed ...

    7. Optical coherence tomography and intravascular ultrasound imaging of bioabsorbable magnesium stent degradation in porcine coronary arteries

      Abstract: Background: Absorbable metallic stents (AMS) composed of magnesium alloy were designed to complete degradation within 90120 days. Among the potential advantages of these stents, when compared to conventional stents, are the elimination of late stent thrombosis, chronic inflammation, and artifacts during noninvasive imaging.Methods: Magnesium-based AMS were deployed in juvenile domestic pig coronary arteries. Angiography, optical coherence tomography (OCT), and intravascular ultrasound (IVUS) were performed before and after implant ...
