   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. (Read Full Article)

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

   Explore Article eurointervention.org (Nov 16 2009) Cardiology

   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.

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

   Explore Article eurointervention.org (Nov 16 2009) Cardiology

   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. (Read Full Article)

5. Reproducibility of quantitative optical coherence tomography for stent analysis

   Explore Article eurointervention.org (Jul 5 2009) Cardiology

   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 in ... (Read Full Article)

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

   Explore Article eurointervention.org (May 20 2009) Cardiology

   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. (Read Full Article)

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

   Explore Article eurointervention.org (Apr 22 2009) Cardiology

   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 ... (Read Full Article)

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

   Explore Article eurointervention.org (Feb 13 2009) Cardiology

   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.
