      How should I treat a complex Post-CABG patient?
      A 69 year old man was admitted with unstable angina (Class IIB). He had a history of chronic renal impairment, diabetes melltus, hypertension and coronary bypass surgery in 1997 (LIMA graft to the LAD and diagonal branch, saphenous vein grafts to the RCA and first marginal branch of LCx). Diagnostic coronary angiogram revealed: occlusion of the proximal LCx and RCA.

    2. Optical coherence tomography assessment of a new dedicated bifurcation stent

      Optical coherence tomography assessment of a new dedicated bifurcation stent
      Dedicated bifurcation stents should facilitate deployment and improved coverage of bifurcational lesions. We used optical coherence tomography (OCT) to assess bifurcation lesions treated with a dedicated stent implanted in the side branch (SB) in conjunction with drug eluting stents in the main vessel (MV) in a culotte-like fashion.

    3. Comparison of optical coherence tomography and intravascular ultrasound for the assessment of in-stent tissue coverage after stent implantation

      Comparison of optical coherence tomography and intravascular ultrasound for the assessment of in-stent tissue coverage after stent implantation
      At present there exists no direct comparative data for the detection of in-stent tissue coverage as assessed by intravascular ultrasound (IVUS) and optical coherence tomography (OCT) in clinical settings. To explore this subject, we investigated the correlation between the IVUS and OCT measurements derived from a contemporary population.

    4. Reproducibility of quantitative optical coherence tomography for stent analysis

      Aims: To assess the inter- and intra- observer reproducibility for strut count, strut apposition and strut tissue coverage measurements with optical coherence tomography (OCT).Methods and results: Ten drug-eluting stents (244 frames, 1712 struts) imaged with OCT nine months after implantation were analysed by two independent analysts. One of the analysts repeated the analysis of five stents (120 frames, 795 struts) one week later. Offline analysis was performed with the proprietary LightLab Imaging software. The number of struts was counted and lumen and stent area contours were traced. Tissue coverage thickness was measured at 360 degrees of vessel circumference and ...

    5. A Multicentre Evaluation of the Safety of Intra-Coronary Optical Coherence Tomography

      Optical coherence tomography (OCT) is increasingly being applied to the coronary arteries. However, the risks associated with the imaging procedure are not yet well defined. The purpose of the present multicentre registry was to access the acute complicaitons associated with the clinical use of intera-coronary OCT in a large number of patients.

    6. In vivo characterisation of coronary plaques with conventional grey-scale intravascular ultrasound: correlation with optical coherence tomography.

      AIMS: Although intravascular ultrasound (IVUS) is widely used, there is limited published data on its accuracy in defining plaque characteristics in vivo. Optical coherence tomography (OCT) is a high-resolution imaging technique that takes advantage of the pronounced optical contrast between the components of normal and diseased vessels. The aim of this study was to evaluate the ability of conventional grey-scale IVUS in identifying in vivo coronary plaque characteristics, in particular lipid content as a marker of the vulnerable plaque, when compared to OCT. METHODS AND RESULTS: In patients undergoing cardiac catheterisation, IVUS and OCT imaging was performed. Detailed qualitative analysis ...

    7. Current and future developments in intracoronary optical coherence tomography imaging

      Current and future developments in intracoronary optical coherence tomography imaging
      Optical Coherence Tomography (OCT) has become a key intracoronary imaging modality able to tranerse some of the limitations of angiography and intravascular ultrasound. In vivo imaging with high resolution (around 15 um) has given unique insights into not only atherosclerotic plaque, but also to the understanding of tissue responses underlying stent implantation.

    8. Novelties in cardiac imaging – Optical Coherence Tomography (OCT)

      Novelties in cardiac imaging – Optical Coherence Tomography (OCT)

      In order to improve our understanding of late stent thrombosis an dto access the individual risk of a patient or lesion, there is clinical need to assess vascular healing after stenting in vivo. We will discuss the potential and limitations of Optical Coherence Tomography (OCT) for imaging of drug eluting stents (DES).

    9. Safety and feasibility of a new non-occlusive technique for facilitated intracoronary optical coherence tomography (OCT) acquisition in various clinical and anatomical scenarios

      Safety and feasibility of a new non-occlusive technique for facilitated intracoronary optical coherence tomography (OCT) acquisition in various clinical and anatomical scenarios
      To facilitate OCT images acquisition we developed a novel, simplified, non-occulsive technique based on manual infusion of a viscous isosmolar solution. The aims of the present study was to address the safety and efficacy of non-occulsive OCT images acquisition modality in a patient population with comples coronary lesions, and in various clinical sceanarios.
