    2. 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 ...

    4. 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 ...

    5. 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 ...

    6. 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

      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 ...

    7. 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

      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 ...

    8. Stent-related defects in patients presenting with stent thrombosis: differences at optical coherence tomography between subacute and late/very late thrombosis in the Mechanism Of Stent Thrombosis (MOST) study

      Stent-related defects in patients presenting with stent thrombosis: differences at optical coherence tomography between subacute and late/very late thrombosis in the Mechanism Of Stent Thrombosis (MOST) study
      Aims: Subacute, late, and very late stent thrombosis (ST) may occur after stent implantation, but they are characterised by different underlying pathophysiological mechanisms. We sought to appraise differences between subacute and late/very late ST at the thrombus site by optical coherence tomography (OCT). The Mechanism Of Stent Thrombosis (MOST) study was a prospective multicentre non-randomised registry which enrolled six subacute ST and six controls (subacute ST study), and 17 ...

    12. Volumetric assessment of lesion severity with optical coherence tomography: relationship with fractional flow reserve

      Volumetric assessment of lesion severity with optical coherence tomography: relationship with fractional flow reserve
      Aims: Frequency-domain optical coherence tomography (FD-OCT) provides a rapid tomographic scan of a coronary vessel, with an accurate reconstruction of its lumen profile. An FD-OCT-based metric that corresponds more closely with physiological significance of lesions may enable more precise guidance of interventional procedures. The aim of this feasibility study was to evaluate a new method for quantifying coronary lesion severity that estimates hyperaemic flow resistance of branched vessel segments imaged ...
