      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 a total of 226±2 stent cross-sections with IVUS and 232±2 stent cross-sections with FD-OCT in 14 patients after stenting. Inter- and intra-observer variability for determining stent volume index ...

      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 of OCT-detected stent edge dissection, tissue protrusion, and ISA during follow-up was investigated. A total of 36 patients with 39 lesions was analyzed. At baseline, OCT showed 12 stent edge ...

    10. Optical coherence tomography evaluation of zotarolimus-eluting stents at 9-month follow-up: comparison with sirolimus-eluting stents

      Explore Heart Cardiology
      Objective: To evaluate the vascular response at 9 months after zotarolimus-eluting stent (ZES; Endeavor) implantation using optical coherence tomography (OCT). These findings were compared with those after implantation of a sirolimus-eluting stent (SES; Cypher Select). Design: Cross-sectional observational study with prospective OCT registry. Setting: Nine months after ZES or SES implantation. Patients and methods: A total of 68 patients (32 ZES and 36 SES) underwent OCT at 9 months after stent implantation. The neointima hyperplasia (NIH) thickness inside each strut and percentage of NIH area at every 1 mm cross section were measured. Main outcome measurement: The degree of neointimal ...

      Frequency and Spatial Distribution of Thin-Cap Fibroatheroma Assessed by 3-Vessel Intravascular Ultrasound and Optical Coherence Tomography: An Ex Vivo Validation and an Initial In Vivo Feasibility Study
      Background: The precursor of plaque rupture is known as thin cap fibroatheroma (TCFA). In the present study, the feasibility and accuracy of optical coherence tomography (OCT) for detecting the frequency and spatial distribution of TCFA was investigated ex vivo, and a 3-vessel OCT analysis was conducted to assess the feasibility of this modality in vivo. Methods and Results: In the ex vivo study, 108 coronary arterial segments from 38 human cadavers were examined by OCT, intravascular ultrasound (IVUS) and histology. The 3-vessel IVUS and OCT examinations were performed in 11 patients with acute coronary syndrome. By histological examination, 30 of ...

    13. Optical coherence tomography after cutting balloon angioplasty

      Explore Heart Cardiology
      Optical coherence tomography (OCT) is a recently developed optical imaging technique that provides high-resolution (approximately 10–20 µm) cross-sectional images of vessels. A 74-year-old man was admitted for chest pain. A coronary angiogram showed diffuse in-stent restenosis of an Express (Boston Scientific Corporation and Medinol Ltd) 2.75 x 15 mm stent which had been implanted in the left anterior descending coronary artery six months earlier (panel A; arrow). Using OCT (Image Wire, LightLab Imaging, Inc) imaging, well-apposed stent struts and neointima formation around the stent were clearly visualised (panel B). We performed angioplasty by using Cutting Balloon Ultra (Boston ...
