    2. Impact of Culprit Plaque and Atherothrombotic Components on Incomplete Stent Apposition in Patients With ST-Elevation Myocardial Infarction Treated With Everolimus-Eluting Stents – An OCTAVIA Substudy –

      Impact of Culprit Plaque and Atherothrombotic Components on Incomplete Stent Apposition in Patients With ST-Elevation Myocardial Infarction Treated With Everolimus-Eluting Stents – An OCTAVIA Substudy –
      Background: The role of culprit plaque and related atherothrombotic components on incomplete stent apposition (ISA) occurrence after primary percutaneous coronary intervention (p-PCI) is unknown. Methods and Results: ST-segment elevation myocardial infarction (STEMI) patients undergoing p-PCI with an everolimus-eluting stent were prospectively investigated with optical coherence tomography (OCT) of the infarct-related artery before, after stenting and at 9 months. OCT data, aspirated thrombus and serum inflammatory biomarkers were analyzed. 114 patients ...

    3. Embolization of Fractured Bioresorbable Scaffold Struts Insights From 2- and 3-Dimensional Optical Coherence Tomography

      Embolization of Fractured Bioresorbable Scaffold Struts Insights From 2- and 3-Dimensional Optical Coherence Tomography
      A 58-year-old diabetic man underwent implantation of 3 overlapping Absorb bioresorbable vascular scaffolds (BVS) (2.5/28, 2.5/28, and 3.0/28 mm) (Abbott Vascular, Santa Clara, California) in a heavily calcified left anterior descending artery stenosis. Optical coherence tomography (OCT) revealed multiple fractures of the 3.0/28 BVS, leading to in-scaffold implantation of a zotarolimus-eluting stent (ZES) ( Figures 1A and 1B ). The 4-month angiography showed a ...

    4. Clinical Impact of OCT Findings During PCI: The CLI-OPCI II Study

      Clinical Impact of OCT Findings During PCI: The CLI-OPCI II Study
      Objectives The goal of this study was to assess the clinical impact of optical coherence tomography (OCT) findings during percutaneous coronary intervention (PCI). Background OCT provides unprecedented high-definition visualization of plaque/stent structures during PCI; however, the impact of OCT findings on outcome remains undefined. Methods In the context of the multicenter CLI-OPCI (Centro per la Lotta contro lInfartoOptimisation of Percutaneous Coronary Intervention) registry, we retrospectively analyzed patients undergoing end-procedural ...

    5. Incidence and potential mechanism of resolved, persistent and newly acquired malapposition three days after implantation of self-expanding or balloon-expandable stents in a STEMI population: insights from optical coherence tomography in the APPOSITION II

      Incidence and potential mechanism of resolved, persistent and newly acquired malapposition three days after implantation of self-expanding or balloon-expandable stents in a STEMI population: insights from optical coherence tomography in the APPOSITION II
      Aims: The aim of the current study was to investigate the frequency and mechanisms of sequential incomplete stent apposition (ISA) changes such as persistent, resolved or newly acquired ISA during the first three days after primary PCI (pPCI) in a matched segment-level analysis, with the comparison between self-expanding and balloon-expandable stents assessed by optical coherence tomography (OCT). Methods and results: The current analysis is a substudy of the APPOSITION II ...

    6. Cyphering the Mechanism of Late Failure of Bioresorbable Vascular Scaffolds in Percutaneous Coronary Intervention of the Left Main Coronary Artery

      Cyphering the Mechanism of Late Failure of Bioresorbable Vascular Scaffolds in Percutaneous Coronary Intervention of the Left Main Coronary Artery
      A 48-year-old woman with history of multiple percutaneous coronary interventions and bypass grafting on the left anterior descending coronary artery presented with unstable angina. Coronary angiography showed a patent left internal mammary artery and de novo critical stenoses of the mid-shaft left main and the unprotected left circumflex coronary artery (LCX). Both lesions were treated with 2 nonoverlapping bioresorbable vascular scaffolds (BVS) (Absorb, Abbott Vascular, Santa Clara, California) 3.5 ...

    8. Optical Coherence Tomography Assessment of Late Intra-Scaffold Dissection - A New Challenge of Bioresorbable Scaffolds

      Optical Coherence Tomography Assessment of Late Intra-Scaffold Dissection - A New Challenge of Bioresorbable Scaffolds
      A 48-year-old man was admitted because of a nonST-segment elevation myocardial infarction. Fifteen months previously, he had received a 3.0 28-mm bioresorbable vascular scaffold (BVS) (Absorb, Abbott Vascular, Santa Clara, California) in the mid-left anterior descending coronary artery for stable angina. Coronary angiography showed a focal in-scaffold restenosis (Figure 1 ). Optical coherence tomography (OCT) (Ilumien, St. Jude Medical, Saint Paul, Minnesota) revealed a heterogeneous pattern consisting of neointimal hyperplasia ...

    9. Optical coherence tomography for coronary imaging

      Optical coherence tomography for coronary imaging
      Optical coherence tomography (OCT) is a novel invasive imaging technique that produces high resolution intracoronary images. Its general principle of operation is similar to IVUS, however OCT uses infrared light, not ultrasound. In the last years, the need for more precise information regarding coronary artery disease to achieve optimal treatment has seen intravascular imaging becoming an area of primary importance in interventional cardiology. OCT in this area has grown and ...

      New Insights on acute expansion and longitudinal elongation of bioresorbable vascular scaffolds In-Vivo and at bench test: A note of caution on reliance to compliance charts and nominal length
      Objectives : We performed systematic optical coherence tomography (OCT) analyses after BVS implantation in a real world setting aiming at evaluating scaffold expansion and longitudinal integrity. Background : A comprehensive elucidation of bioresorbable vascular scaffolds (BVS) acute performance in the real-world setting is lacking Methods : Acute BVS expansion compared with compliance chart information and longitudinal integrity were assessed in 29 patients (32 lesions) by OCT. In addition, bench experiments with 4 scaffolds ...

      Mechanisms of Atherothrombosis and Vascular Response to Primary Percutaneous Coronary Intervention in Women Versus Men With Acute Myocardial Infarction : Results of the OCTAVIA (Optical Coherence Tomography Assessment of Gender Diversity in Primary Angiop
      Objectives This study sought to assess in vivo sex differences in the pathophysiology of ST-segment elevation myocardial infarction (STEMI) and vascular response to primary percutaneous coronary intervention (PCI). Background There is no consensus on whether differences in the pathophysiology of STEMI and response to primary PCI between women and men reflect biological factors as opposed to differences in age. Methods In this prospective, multicenter study, 140 age-matched men and women ...
