    2. 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 ...

    4. Spontaneous Coronary Artery Dissection: Pathophysiological Insights From Optical Coherence Tomography

      Spontaneous Coronary Artery Dissection: Pathophysiological Insights From Optical Coherence Tomography
      Objectives This study used optical coherence tomography to investigate the mechanism of false lumen (FL) formation in spontaneous coronary artery dissection (SCAD) by studying: 1) differences between fenestrated and nonfenestrated SCAD; 2) vasa vasorum density; and 3) light attenuation characteristics of the FL. Background SCAD is an increasingly recognized cause of acute coronary syndromes , characterized by FL formation and compression of the true lumen (TL). The mechanisms underlying FL formation ...

    5. Qualitative and quantitative neointimal characterization by optical coherence tomography in patients presenting with in-stent restenosis

      Qualitative and quantitative neointimal characterization by optical coherence tomography in patients presenting with in-stent restenosis
      Aims To describe optical coherence tomography (OCT) findings in patients with in-stent restenosis (ISR) and determine predictors of neointimal patterns and neoatherosclerosis. Methods and results Patients undergoing OCT prior to PCI for ISR in three European centres were included. Analyses were performed in a core laboratory. Qualitative and quantitative [gray-scale signal intensity (GSI)] neointima analyses were performed on a per quadrant basis. A total of 107 patients were included. Predominantly ...

    6. Accuracy of intravascular ultrasound and optical coherence tomography in identifying functionally significant coronary stenosis according to vessel diameter: A meta-analysis of 2,581 patients and 2,807 lesions

      Accuracy of intravascular ultrasound and optical coherence tomography in identifying functionally significant coronary stenosis according to vessel diameter: A meta-analysis of 2,581 patients and 2,807 lesions
      Introduction Accuracy of intracoronary imaging to discriminate functionally significant coronary stenosis according to vessel diameter remains to be defined. Methods PubMed, Scopus, and Google Scholar were systematically searched for studies assessing diagnostic accuracy (area under the receiver operating characteristic curve [AUC], the primary end point) and sensitivity and specificity (the secondary end points) of minimal luminal area (MLA) or of minimal luminal diameter (MLD) derived from intravascular ultrasound (IVUS) or ...

    7. Combined In Vivo Insights Unraveling the Underlying Substrate of an Acute Myocardial Infarction Treated With a Bioabsorbable Vascular Scaffold

      Combined In Vivo Insights Unraveling the Underlying Substrate of an Acute Myocardial Infarction Treated With a Bioabsorbable Vascular Scaffold
      An 86-year-old man presented with an ST-segment elevation inferior myocardial infarction. Coronary angiography revealed a large filling defect in the proximal right coronary artery (Figure 1 A) that was significantly reduced after thromboaspiration (Figure 1 B). On visual examination, the aspirated material appeared to be just a large red thrombus (Figure 1 D and Figure 1 E). Optical coherence tomography (OCT) disclosed the culprit lesion, which consisted of a red ...

    8. Combined use of optical coherence tomography and intravascular ultrasound imaging for the evaluation of stent thrombosis

      Combined use of optical coherence tomography and intravascular ultrasound imaging for the evaluation of stent thrombosis
      Stent thrombosis (ST) represents the most feared complication after the percutaneous treatment of a coronary stenosis, usually involving very serious or fatal consequences for the patient. The interest in ST was initiated after the first longitudinal follow-up of drug-eluting stents (DES), which dramatically decrease the rate of restenosis. Further investigation revealed that ST is not a class effect, also affecting bare metal stents, and that several factors are potentially implicated ...

    9. Optical coherence tomography: from research to clinical application

      Optical coherence tomography: from research to clinical application
      Optical coherence tomography (OCT) has revolutionized intracoronary imaging. The unprecedented spatial resolution of this technique (15 m) provides unique insights on the microstructure of the coronary wall. Currently, OCT is increasingly used in clinical practice and also constitutes an emerging, highly robust, research tool. OCT allows detailed visualization of atherosclerotic plaques and provides reliable information on plaque composition (lipid, fibrous, calcified) although its limited tissue penetration usually precludes a comprehensive ...
