    2. Intracoronary Optical Frequency Domain Imaging for Identifying Stent-Related Complications

      Intracoronary Optical Frequency Domain Imaging for Identifying Stent-Related Complications
      Percutaneous coronary intervention is the most common treatment of coronary artery disease with the majority of cases undergoing stent implantation. Furthermore, adequate stent deployment is of primary importance to avoid late stent thrombosis and achieve a favorable clinical outcome. Optical coherence tomography (OCT) is a new imaging modality that utilizes advanced photonics and fiberoptics to obtain intravascular images on a microscopic scale. Today, many new drug-eluting stents (DES) are now ...

    3. Plaque and thrombus evaluation by optical coherence tomography

      Plaque and thrombus evaluation by optical coherence tomography
      Intravascular Optical Coherence Tomography has been explored as an imaging tool for vessel wall and thrombus characterization. OCT enables a high resolution arterial wall imaging, and light properties allow tissue characterization. It has been proved one of the most valuable imaging modalities for the evaluation of vulnerable plaque and thrombus. OCT has a unique capacity in volumetric quantification of calcium, and unlike ultrasound, light can easily penetrate calcified plaques. Finally ...

    6. Clinical Classification and Plaque Morphology Determined by Optical Coherence Tomography in Unstable Angina Pectoris

      Clinical Classification and Plaque Morphology Determined by Optical Coherence Tomography in Unstable Angina Pectoris
      Unstable angina pectoris (UAP) is categorized with the Braunwald classification. However, the association of clinical presentation and plaque structure/function has not yet been elucidated in relation to cause. We used optical coherence tomography to investigate this relation. One hundred fifteen patients with primary UAP were categorized according to the Braunwald classification. Patients with class I UAP had the highest frequency of ulcers without fibrous cap disruption (p = 0.003 ...

    8. Association of monocyte subset counts with coronary fibrous cap thickness in patients with unstable angina pectoris

      Association of monocyte subset counts with coronary fibrous cap thickness in patients with unstable angina pectoris
      Abstract: Objectives: We examined whether distinct monocyte subsets relate in specific ways to coronary fibrous cap thickness (FCT) in patients with unstable angina pectoris (UAP).Methods: Forty patients with UAP who underwent percutaneous coronary intervention were enrolled in this study. The changes in the non-culprit FCT were assessed by optical coherence tomography (OCT) at baseline and after 9 months. The distinct monocyte subsets (CD14+CD16−CCR2+ and CD14+CD16+CX3CR1 ...

    9. Relation of Microchannel Structure Identified by Optical Coherence Tomography to Plaque Vulnerability in Patients With Coronary Artery Disease

      Relation of Microchannel Structure Identified by Optical Coherence Tomography to Plaque Vulnerability in Patients With Coronary Artery Disease
      Increased neovascularization in atherosclerotic plaques is associated with plaque vulnerability. The high resolution of optical coherence tomography (OCT) might provide a chance to directly visualize plaque neovascularization in vivo. The aim of the present study was to investigate the relation between microchannels in culprit plaques identified by OCT and plaque vulnerability in patients with coronary artery disease. A total of 63 consecutive patients with coronary artery disease who had undergone ...

    10. Optical coherence tomography in unprotected left main coronary artery stenting

      Optical coherence tomography in unprotected left main coronary artery stenting
      Aims: Delayed or incomplete stent endothelisation and stent malapposition may predispose to DES thrombosis that can be catastrophic event in the left main coronary artery (LMCA). OCT can accurately identify stents struts and arterial tissue, but is limited by the need of vessel blood clearance and penetration; also no data exists on its use in LMCA. We sought to verify whether optical coherence tomography (OCT) can accurately assess arterial wall ...

    11. Multiple Coronary Lesion Instability in Patients With Acute Myocardial Infarction as Determined by Optical Coherence Tomography

      Autopsy studies have suggested that acute myocardial infarction (AMI) represents a pan-coronary process of vulnerable plaque development. We performed multifocal optical coherence tomographic (OCT) examination to compare coronary lesion instability between AMI and stable angina pectoris (SAP). A total of 42 patients with AMI (n = 26) or SAP (n = 16) who had multivessel disease and underwent multivessel coronary intervention were enrolled in the present study. The OCT examination was performed ...
