    2. 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 ...

    3. Impact of stent platform on longitudinal stent deformation: an in vivo frequency domain optical coherence tomography study

      Impact of stent platform on longitudinal stent deformation: an in vivo frequency domain optical coherence tomography study
      Recently, longitudinal coronary stent deformation has been highlighted as a possible cause of drug-eluting stent failure. Although bench tests and in vivo studies have demonstrated difference in longitudinal stent strength among the stents with different platforms, its clinical impact is still unknown. Furthermore, it is unknown if modified stent platform favorably affect the incidence of stent deformation. The aim of this study was to investigate the longitudinal deformation of the ...

    4. High Platelet Reactivity and Intrastent Thrombi Assessed by OCT After DES

      High Platelet Reactivity and Intrastent Thrombi Assessed by OCT After DES
      High platelet reactivity (HPR) on clopidogrel may be related to stent thrombosis after drug-eluting stent (DES) implantation (1) . To investigate the relationship between HPR and intrastent thrombi following DES implantation, 202 lesions treated with DES from 109 patients were studied. Coronary angiography and optical coherence tomography (OCT) examination were performed as parts of routine follow-up examination at our institution except for the presence of renal dysfunction or congestive heart failure ...

    5. Detection of Plaque Neovascularization by Optical Coherence Tomography: Ex Vivo Feasibility Study and In Vivo Observation in Patients With Angina Pectoris

      Detection of Plaque Neovascularization by Optical Coherence Tomography: Ex Vivo Feasibility Study and In Vivo Observation in Patients With Angina Pectoris
      Abstract: Objectives. The purposes of this study were: (1) to assess the feasibility of optical coherence tomography (OCT) for detecting neovascularization; and (2) to clarify the impact of plaque neovascularization on coronary vessel behavior over time. Background. Plaque neovascularization may be related to plaque vulnerability. Methods. In an ex vivo study, a total of 55 coronary plaques from 31 human cadavers were examined by OCT. Plaque neovascularization was diagnosed based ...

    6. In-stent neointimal characteristics and late neointimal response after drug-eluting stent implantation: A preliminary observation

      In-stent neointimal characteristics and late neointimal response after drug-eluting stent implantation: A preliminary observation
      Background Progressive neointimal proliferation may lead to late restenosis and/or neoatherosclerosis after drug-eluting stent (DES) implantation. Late neointimal response may be different among different tissue characteristics. The aim of this study was to assess impact of in-stent neointimal characteristics on late neointimal response following DES implantation. Methods Serial (median 270 days and median 551 days after stent implantation) optical coherence tomography (OCT) examinations were performed in 42 stented lesions ...

    7. Calcified plaque ablated by rotational atherectomy visualised by optical coherence tomography

      Calcified plaque ablated by rotational atherectomy visualised by optical coherence tomography
      This paper also includes accompanying supplementary data published online at: http://www.pcronline.com/eurointervention/86th_issue/62 Calcification is visualised by optical coherence tomography (OCT) as a well-delineated, signal-poor region with sharp borders. A 63-year-old female patient with stable angina underwent percutaneous coronary intervention. OCT (C7 Dragonfly, ILUMIEN OCT system; St. Jude Medical, St. Paul, MN, USA) showed lumen narrowing with heavily calcified plaque (Figure 1A) . Rotational atherectomy (RA) was ...

    8. A unique feature of thin flat thrombus visualised by optical coherence tomography

      A unique feature of thin flat thrombus visualised by optical coherence tomography
      Optical coherence tomography (OCT) has recently been developed as a high-resolution intravascular imaging modality, detecting small abnormal structures in the coronary lumen that could not be visualised by intravascular ultrasound (IVUS). A 77-year-old man died with acute myelogenous leukemia. After he died, the coronary artery was imaged by OCT (ImageWire; LightLab Imaging, Westford, MA, USA) and IVUS (Atlantis SR Pro, 40 MHz; Boston Scientific, Natick, MA, USA). OCT clearly demonstrated ...

    9. 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 ...

      Natural History of Stent Edge Dissection, Tissue Protrusion and Incomplete Stent Apposition Detectable Only on Optical Coherence Tomography After Stent Implantation
      Background: The clinical impact of stent edge dissection, tissue protrusion, and incomplete stent apposition (ISA) after stent implantation, detectable only on optical coherence tomography (OCT), is still unknown because the natural course has not been investigated. Methods and Results: All consecutive patients with angina pectoris in whom both intravascular ultrasound (IVUS) and OCT were performed immediately after stenting and at follow-up were included in the present study. The natural history ...
