    1. Clinical use of intracoronary imaging. Part 2: acute coronary syndromes, ambiguous coronary angiography findings, and guiding interventional decision-making: an expert consensus document of the European Association of Percutaneous Cardiovascular Intervent

      Clinical use of intracoronary imaging. Part 2: acute coronary syndromes, ambiguous coronary angiography findings, and guiding interventional decision-making: an expert consensus document of the European Association of Percutaneous Cardiovascular Intervent

      This consensus document is the second of two reports summarizing the views of an expert panel organized by the European Association of Percutaneous Cardiovascular Interventions (EAPCI) on the clinical use of intracoronary imaging including intravascular ultrasound (IVUS), optical coherence tomography (OCT), and near infrared spectroscopy (NIRS)-IVUS. Beyond guidance of stent selection and optimization of deployment, invasive imaging facilitates angiographic interpretation and may guide treatment in acute coronary syndrome. Intravascular imaging can provide additional important diagnostic information when confronted with angiographically ambiguous lesions and allows assessment of plaque morphology enabling identification of vulnerability characteristics. This second document focuses on useful ...

    2. An observational study of clinical outcomes of everolimus-eluting bioresorbable scaffolds comparing the procedural use of optical coherence tomography against angiography alone

      An observational study of clinical outcomes of everolimus-eluting bioresorbable scaffolds comparing the procedural use of optical coherence tomography against angiography alone

      Objectives The introduction of the bioresorbable vascular scaffold (BVS) has led to new avenues of coronary intervention; however, there have been concerns raised regarding the mechanical properties of BVS and the resulting in-stent thrombosis. We aim to assess whether intracoronary imaging improves outcome in patients following BVS implantation. Patients and methods All patients undergoing percutaneous coronary intervention using BVS at a single centre between June 2013 and June 2016 were included in this study ( n =79). Percutaneous coronary intervention with BVS was performed according to conventional practice: predilatation, postdilatation and intracoronary assessment with optical coherence tomography (OCT) according to operator ...

    3. Intracoronary optical coherence tomography: Clinical and research applications and intravascular imaging software overview

      Intracoronary optical coherence tomography: Clinical and research applications and intravascular imaging software overview

      By providing valuable information about the coronary artery wall and lumen, intravascular imaging may aid in optimizing interventional procedure results and thereby could improve clinical outcomes following percutaneous coronary intervention (PCI). Intravascular optical coherence tomography (OCT) is a light-based technology with a tissue penetration of approximately 1 to 3 mm and provides near histological resolution. It has emerged as a technological breakthrough in intravascular imaging with multiple clinical and research applications. OCT provides detailed visualization of the vessel following PCI and provides accurate assessment of post-procedural stent performance including detection of edge dissection, stent struts apposition, tissue prolapse, and healing ...

    4. OCT for the Identification of Vulnerable Plaque in Acute Coronary Syndrome

      OCT for the Identification of Vulnerable Plaque in Acute Coronary Syndrome

      After 2 decades of development and use in interventional cardiology research, optical coherence tomography (OCT) has now become a core intravascular imaging modality in clinical practice. Its unprecedented spatial resolution allows visualization of the key components of the atherosclerotic plaque that appear to confer “vulnerability” to rupture—namely the thickness of the fibrous cap, size of the necrotic core, and the presence of macrophages. The utility of OCT in the evaluation of plaque composition can provide insights into the pathophysiology of acute coronary syndrome and the healing that occurs thereafter. A brief summary of the principles of OCT technology and ...
