    2. 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 ...

    3. New implication of three-dimensional optical coherence tomography in optimising bifurcation PCI

      New implication of three-dimensional optical coherence tomography in optimising bifurcation PCI
      With the advance of optical coherence tomography (OCT) technology, three-dimensional (3D) reconstruction based on the optical coherence tomography has become feasible. In bifurcation lesions, 3D OCT may guide positioning of the wire through the appropriate (distal) cells. The early studies suggested that such a guidance strategy could reduce the incidence of malapposition in bifurcation lesions. The pre-installed real-time 3D OCT on the console will promote the utilisation of 3D assessment ...

    4. Early and late optical coherence tomography findings following everolimus-eluting bioresorbable vascular scaffold implantation in myocardial infarction: a preliminary report

      Early and late optical coherence tomography findings following everolimus-eluting bioresorbable vascular scaffold implantation in myocardial infarction: a preliminary report
      Introduction: Although bioresorbable vascular scaffolds (BVS) have been used with promising results in patients with stable and unstable angina, little is known about the acute vascular response following BVS implantation in myocardial infarction. We present angiographic and OCT findings from the first patients undergoing bioresorbable vascular scaffold (BVS) implantation for non-ST-elevation myocardial infarction (NSTEMI) or ST-elevation myocardial infarction (STEMI) in our institution. Methods: The first 5 patients with NSTEMI and ...

      Serial 2-Dimensional and 3-Dimensional Optical Coherence Tomography Assessment of Overhanging Struts of Drug-Eluting Absorbable Metal Scaffold
      A 75-year-old woman with stable angina pectoris underwent percutaneous coronary intervention of the left anterior descending coronary artery, whereby a 3.25/16-mm paclitaxel-eluting absorbable metal scaffold (DREAMS, Biotronik, Blach, Switzerland) was successfully implanted. Post-procedural angiography showed excellent results without pinching of the side branch ostium. The patient experienced no procedure-related complications, and was discharged 48 h after the procedure on dual antiplatelet therapy. Optical coherence tomography (OCT) (LightLab Imaging ...

      Feature Of The Week 3/2/14: Erasmus MC Investigates Fusion of OCT and Coronary Angiography for Accurate Assessment of the Local Blood Flow Patterns
      Intravascular ultrasound (IVUS)-based reconstructions have been traditionally used to examine the effect of endothelial shear stress (ESS) on neointimal formation. The aim of this analysis is to compare the association between ESS and neointimal thickness (NT) in models obtained by the fusion of optical coherence tomography (OCT) and coronary angiography and in the reconstructions derived by the integration of IVUS and coronary angiography. We analyzed data from six patients ...

      Effect of the Endothelial Shear Stress Patterns on Neointimal Proliferation Following Drug-Eluting Bioresorbable Vascular Scaffold Implantation : An Optical Coherence Tomography Study
      Objectives The goal of this study was to investigate the effect of endothelial shear stress (ESS) on neointimal formation following an Absorb bioresorbable vascular scaffold (BVS) (Abbott Vascular, Santa Clara, California) implantation. Background Cumulative evidence, derived from intravascular ultrasoundbased studies, has demonstrated a strong association between local ESS patterns and neointimal formation in bare-metal stents, whereas in drug-eluting stents, there are contradictory data about the effect of ESS on the ...

      Coronary evaginations are associated with positive vessel remodelling and are nearly absent following implantation of newer-generation drug-eluting stents: an optical coherence tomography and intravascular ultrasound study
      Objectives The purpose of this study was to assess the occurrence, predictors, and mechanisms of optical coherence tomography (OCT)-detected coronary evaginations following drug-eluting stent (DES) implantation. Background Angiographic ectasias and aneurysms in stented segments have been associated with a risk of late stent thrombosis. Using OCT, some stented segments show coronary evaginations reminiscent of ectasias. Methods Evaginations were defined as outward bulges in the luminal contour between struts. They ...

    13. Natural history of optical coherence tomography-detected non-flow-limiting edge dissections following drug-eluting stent implantation

      Natural history of optical coherence tomography-detected non-flow-limiting edge dissections following drug-eluting stent implantation
      Aims: Angiographic evidence of edge dissections has been associated with a risk of early stent thrombosis. Optical coherence tomography (OCT) is a high-resolution technology detecting a greater number of edge dissections -particularly non-flow-limiting- compared to angiography. Their natural history and clinical implications remain unclear. The objectives of the present study were to assess the morphology, healing response, and clinical outcomes of OCT-detected edge dissections using serial OCT imaging at baseline ...

      In vivo assessment of the three-dimensional haemodynamic micro-environment following drug-eluting bioresorbable vascular scaffold implantation in a human coronary artery: fusion of frequency domain optical coherence tomography and angiography
      The biplane angiographic data, acquired after implantation of an everolimus-eluting bioresorbable vascular scaffold (Absorb BVS; Abbott Vascular, Santa Clara, CA, USA) in the right coronary artery of a 46-year-old patient, were separately fused with frequency domain optical coherence tomography (FD-OCT) and intravascular ultrasound (IVUS) data to reconstruct the three-dimensional (3-D) anatomy. The local shear stress (SS) distribution in the FD-OCT- and IVUS-based models was assessed using computational fluid dynamics. The ...

      Randomized study to assess the effect of thrombus aspiration on flow area in patients with ST-elevation myocardial infarction: an optical frequency domain imaging study—TROFI trial
      Aims Primary percutaneous coronary intervention (PPCI) with thrombectomy (TB) seems to reduce the thrombus burden, resulting in a larger flow area as measured with optical frequency domain imaging (OFDI). Methods and results In a multi-centre study, 141 patients with ST elevation myocardial infarction 12 h from onset were randomized to either PPCI with TB using an Eliminate catheter (TB: n = 71) or without TB (non-TB: n = 70), having operators blinded ...
