    2. Current status of hybrid intravascular ultrasound and optical coherence tomography catheter for coronary imaging and percutaneous coronary intervention

      Current status of hybrid intravascular ultrasound and optical coherence tomography catheter for coronary imaging and percutaneous coronary intervention
      Both intravascular ultrasound (IVUS) and optical coherence tomography (OCT) play a crucial role in elucidating the pathophysiology of coronary artery disease (CAD) with the goal to improve patient outcomes of medical and/or interventional CAD management. However, no single intravascular imaging technique has been proven to provide complete and detailed evaluation of all CAD lesions due to some limitations. Although sequential use of multiple modalities may sometimes be performed, there ...

    3. Randomized Comparison Between Everolimus-Eluting Bioresorbable Scaffold and Metallic Stent Multimodality Imaging Through 3 Years

      Randomized Comparison Between Everolimus-Eluting Bioresorbable Scaffold and Metallic Stent Multimodality Imaging Through 3 Years
      Objectives The aim of this study was to investigate the vascular responses and fates of the scaffold after bioresorbable vascular scaffold (BVS) implantation using multimodality imaging. Background Serial comprehensive image assessments after BVS implantation in the context of a randomized trial have not yet been reported. Methods In the ABSORB Japan trial, 400 patients were randomized to a BVS (n = 266) or a cobalt-chromium everolimus-eluting stent (n = 134). Through 3 ...

    4. Comparing the vascular response in implantation of self-expanding, bare metal nitinol stents or paclitaxel-eluting nitinol stents in superficial femoral artery lesions: a serial optical frequency domain imaging study

      Comparing the vascular response in implantation of self-expanding, bare metal nitinol stents or paclitaxel-eluting nitinol stents in superficial femoral artery lesions: a serial optical frequency domain imaging study
      Aims: This study sought to investigate differences in vascular response between self-expanding bare metal nitinol stents (BMS) and paclitaxel-eluting nitinol stents (PES), in superficial femoral artery (SFA) disease, using optical frequency domain imaging (OFDI). Methods and results: Six months after stent implantation, follow-up quantitative vascular angiography (QVA) and OFDI assessment were scheduled to evaluate vascular response.

    5. Acute stent recoil and optimal balloon inflation strategy: an experimental study using real-time optical coherence tomography

      Acute stent recoil and optimal balloon inflation strategy: an experimental study using real-time optical coherence tomography
      Aims: Our aim was to evaluate stent expansion and acute recoil at deployment and post-dilatation, and the impact of post-dilatation strategies on final stent dimensions. Methods and results: Optical coherence tomography (OCT) was performed on eight bare metal platforms of drug-eluting stents (3.0 mm diameter, n=6 for each) during and after balloon inflation in a silicone mock vessel. After nominal-pressure deployment, a single long (30 sec) vs. multiple ...

    6. Quantitative precision of optical frequency domain imaging: direct comparison with frequency domain optical coherence tomography and intravascular ultrasound

      Quantitative precision of optical frequency domain imaging: direct comparison with frequency domain optical coherence tomography and intravascular ultrasound
      No systematic validation study is available with optical frequency domain imaging (OFDI), directly compared with frequency domain optical coherence tomography (FD-OCT) and intravascular ultrasound (IVUS). Controversy also remains about the impact of different stent contour tracing methods by OFDI/FD-OCT. In vitro: coronary phantom models (1.515.04 mm) were imaged with OFDI, FD-OCT, and IVUS, demonstrating excellent quantitative precision with a slight overestimation of mean lumen diameter (difference 0 ...

    7. Variability in quantitative and qualitative analysis of intravascular ultrasound and frequency domain optical coherence tomography

      Variability in quantitative and qualitative analysis of intravascular ultrasound and frequency domain optical coherence tomography
      Background: Frequency-domain optical coherence tomography (FD-OCT) is an intravascular imaging technique now available in the United States. However, the importance of level of training required for analysis using intravascular ultrasound (IVUS) and FD-OCT is unclear. The aim of this study was to evaluate inter- and intra-observer variability between expert and beginner analysts interpreting IVUS and FD-OCT images. Methods and results : Two independent expert analysts and two independent beginner analysts evaluated ...

    11. Evaluation of the Peri-strut Low Intensity Area Following Sirolimus- and Paclitaxel-Eluting Stents Implantation: Insights From an Optical Coherence Tomography Study in Humans

      Evaluation of the Peri-strut Low Intensity Area Following Sirolimus- and Paclitaxel-Eluting Stents Implantation: Insights From an Optical Coherence Tomography Study in Humans
      Background: In previous pathological studies, paclitaxel-eluting stents (PES) showed greater fibrin deposition around stent struts, while sirolimus-eluting stent (SES) showed predominance of inflammatory cells with less fibrin deposition than PES. However, there are limited in-vivo data clarifying those qualitative differences in the process of vascular healing after 1st-generation drug-eluting stents (DES) implantation. A recent animal study has shown that peri-strut low intensity area (PLIA) seen in optical coherence tomography (OCT ...

      Drug-Eluting Stents: Insights From Invasive Imaging Technologies
      Drug-eluting stents (DES) represent a revolutionary technology in their unique ability to provide both mechanical and biological solutions simultaneously to the target lesion. As a result of biological effects from the pharmacological agents and interaction of DES components with the arterial wall, considerable differences exist between DES and conventional bare metal stents (BMS), yet some of the old lessons learned in the BMS era remain clinically significant. In this context ...

    15. Local Determinants and Clinical Significance of Thrombus Formation Following Sirolimus-Eluting Stent Implantation: Insights from Optical Coherence Tomography Analysis

      Angioscopic analyses have shown the presence of subclinical thrombus in sirolimus-eluting stents (SES) is more common than the clinical incidence of stent thrombosis. However, the determinants and long term significance of subclinical thrombus remain unknown. Thirty five patients (44 stents) who received SES underwent 6 months follow-up optical coherence tomography (OCT). Patients were divided into 2 groups according to the presence of thrombus by OCT. Cross-sectional images were analyzed every ...
