    2. “Continuous-Flushing” OCT Identifies Vulnerable Plaques

      New findings show that using non-occlusive optical coherence tomography (OCT) in patients with acute coronary syndromes can help identify vulnerable thin-capped fibroatheromas (TCFAs) and ruptured plaques in culprit coronary arteries. The study, published online ahead of print in the August 4, 2008, issue of American Journal of Cardiology, also found TCFAs to significantly correlate with high plasma levels of C-reactive protein (CRP). Atsushi Tanaka, MD, and colleagues from Wakayama University ...

    4. Effect of statin therapy on coronary fibrous-cap thickness in patients with acute coronary syndrome: Assessment by optical coherence tomography study

      Background The thickness of coronary fibrous caps is a major determinant of vulnerable plaques. Several clinical trials have suggested that statin therapy could stabilize vulnerable plaques. Recently, optical coherence tomography (OCT) has been proposed as an effective histology-resolution imaging modality for assessing such micro-structural changes. Methods Forty AMI patients with hyperlipidemia were enrolled and underwent percutaneous coronary intervention (PCI). They were divided into two groups; statin treatment group (n = 23 ...

    5. Identification of multiple plaque ruptures by optical coherence tomography in a patient with acute myocardial infarction: a three-vessel study

      Optical coherence tomography (OCT) is a new imaging modality capable of obtaining cross-sectional images of coronary vessels with a high resolution of about 10 µm, which is about 10-fold greater than that of intravascular ultrasound. A 57-year-old man was admitted to our hospital with acute posterior myocardial infarction. An emergency coronary angiography demonstrated 99% stenosis (TIMI 2 flow) in segment 11 of the left circumflex artery, and 75% stenosis in ...

    6. Safety and Feasibility of an Intravascular Optical Coherence Tomography Image Wire System in the Clinical Setting

      Optical coherence tomography (OCT) is a fiber-optic technology that enables high-resolution intracoronary imaging. The aim of this study was to evaluate the safety and feasibility of intracoronary imaging with OCT in the clinical setting; 76 patients with coronary artery disease from 8 centers were enrolled. The OCT imaging system (ImageWire, Light Imaging Inc., Westford, Massachusetts) consists of a 0.006 inch fiber-optic core that rotates within a 0.016 inch ...

    7. Optical coherence tomography after cutting balloon angioplasty

      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 ...
