    1. 3D reconstruction of coronary artery bifurcations from coronary angiography and optical coherence tomography: feasibility, validation, and reproducibility

      3D reconstruction of coronary artery bifurcations from coronary angiography and optical coherence tomography: feasibility, validation, and reproducibility

      The three-dimensional (3D) representation of the bifurcation anatomy and disease burden is essential for better understanding of the anatomical complexity of bifurcation disease and planning of stenting strategies. We propose a novel methodology for 3D reconstruction of coronary artery bifurcations based on the integration of angiography, which provides the backbone of the bifurcation, with optical coherence tomography (OCT), which provides the vessel shape. Our methodology introduces several technical novelties to tackle the OCT frame misalignment, correct positioning of the OCT frames at the carina, lumen surface reconstruction, and merging of bifurcation lumens. The accuracy and reproducibility of the methodology were ...

    2. Evolution of Intravascular Assessment Of Coronary Anatomy And Physiology: From Ultrasound Imaging to Optical and Flow Assessmen

      Evolution of Intravascular Assessment Of Coronary Anatomy And Physiology: From Ultrasound Imaging to Optical and Flow Assessmen

      The fact that coronary angiography has limitations in terms of precise estimation and progression of atherosclerosis has been partially overcome during the last years by the use of new techniques. Catheter based invasive modalities are of a profound clinical importance in regards to accurate assessment of coronary anatomy and physiology and the choice of the appropriate treatment strategy for each patient. Also their potential in clinical investigation projects is of great interest. This current review summarizes the basic principles of these methodologies and evidently highlights not only their use in clinical practice but also their contribution in clinical outcomes.

    3. Interventional Cardiology: Principles and Practice (Book)

      Interventional Cardiology: Principles and Practice (Book)
      This new volume offers a balanced and current presentation of the key topics that form the cornerstone of an Interventional Cardiology training program including sections on Optical Coherence Tomography. Globally recognized editors and contributors draw on their years of experience to provide practical information emphasizing the basics of material selection and optimal angiographic setup for purposes of the interventional procedure. Comprehensive chapters address the different techniques of approaching complex coronary lesions such as chronic occlusions, bifurcations, and unprotected left main lesions.

    4. First-in-Man 1-Year Clinical Outcomes of the Catania Coronary Stent System With Nanothin Polyzene-F in De Novo Native Coronary Artery Lesions: The Atlanta (Assessment of The Latest Non-Thrombogenic Angioplasty stent) Trial

      Objectives: This study sought to assess safety and efficacy of implantation of the Catania Coronary Stent System with Nanothin Polyzene-F (CeloNova BioSciences, Newnan, Georgia) in human coronary arteries with clinical data and comprehensive intracoronary imaging. Background: Novel approaches to modify stents (e.g., bioactive agents, coatings) have been developed to address the limitations of bare-metal and drug-eluting stents (e.g., restenosis, target lesion revascularization [TLR], late thrombosis). Methods: This first-in-man study using the Catania stent is a prospective, single center, nonrandomized, single-arm study of 55 patients with symptomatic ischemic heart disease with de novo, obstructive lesions of native coronary arteries ...
