This book was released on 2017-11-15 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although improved treatments have reduced the rates of acute complications from myocardial infarction, sequelae such as heart failure and sudden death threaten the future wellbeing of those patients. Secondary prevention after myocardial infarction is related to cardiovascular risk factors and the effect of the infarct on left ventricular function. Cardiovascular magnetic resonance imaging (CMR) is necessary to determine the size of the infarct scar and can with great precision determine left ventricular volumes, left ventricular ejection fraction, and deformation (strain and torsion). The purpose of this thesis was to improve on CMR methods to facilitate image acquisition and post processing in patients with high risk of coronary artery disease (CAD). In Paper 1, a three-dimensional phase-sensitive inversion-recovery (3D PSIR) sequence was modified to measure T1 during a single breath hold. The measured T1 values were used to extrapolate a map of T1 relaxation, which avoided the time-consuming manual determination of the inversion time. The data collection consisted of phantom experiments, Monte Carlo simulations of the effect of various heart rates, and clinical investigation of 18 patients with myocardial infarction. Scar images created with the modified sequence were compared to those created with the standard sequence. The 3D PSIR sequence was able to measure T1 relaxation with a high accuracy up to 800 ms, which is in the suitable range for scar imaging. Simulated arrhythmias showed that the method was robust and able to tolerate some variation in heart rate. The modified sequence provides measurements of inversion time that can be used to facilitate standard scar imaging or to reconstruct synthetic scar images. Images of infarct scar obtained with the 3D PSIR sequence bore striking similarity to images obtained with the standard sequence. In Paper 2, 125 patients with high risk of CAD were investigated using the displacement encoding with stimulated echoes (DENSE) sequence. Image segments with infarct scar area >50% (transmurality) could be identified with a sensitivity of 95% and a specificity of 80% based on circumferential strain calculated from the DENSE measurements. The DENSE sequence was also applied in other directions, but its sensitivity and specificity to detect scar was lower than when used for circumferential strain. In Paper 3, 90 patients with high risk of CAD were examined by DENSE, tagging with harmonic phase (HARP) imaging and cine imaging with feature tracking (FT), to detect cardiac abnormalities as manifested in end-systolic circumferential strain. Circumferential strain calculated with DENSE had higher sensitivity and specificity than the competing methods to detect infarction with transmurality >50%. Global circumferential strain measured by DENSE correlated better with global parameters such as left ventricular ejection fraction, myocardial wall mass, left ventricular end-diastolic and end-systolic volume; than strain measured by FT or HARP. In Paper 4, myocardial torsion was investigated using DENSE, HARP, and FT in 48 patients with high risk of CAD. Torsion measured by each of the three methods was correlated with other global measures such as left ventricular ejection fraction, left ventricular mass, and left ventricular end-diastolic and end-systolic volumes. The torsion measurements obtained with DENSE had a stronger relationship with left ventricular ejection fraction, left ventricular mass, and volumes than those obtained with HARP or FT. DENSE was superior to the other methods for strain and torsion measurement and can be used to describe myocardial deformation quantitatively and objectively.

This book was released on 2023-09-26 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This heavily updated textbook focuses on the use of cardiac magnetic resonance (CMR) imaging in pediatric and adult patients with congenital heart disease. Over past two decades, CMR has come to occupy an ever more important place in the assessment and management of patients with congenital heart defects (CHD) and other cardiovascular disorders. The modality offers an ever-expanding amount of information about the heart and circulation, provides outstanding images of cardiovascular morphology and function, is increasingly being used to detect pathologic fibrosis, and has an expanding role in the assessment of myocardial viability. Magnetic Resonance Imaging of Congenital Heart Disease is an excellent foundation for any reader not familiar with the field whether they are imagers or clinicians who deal with cardiovascular disease. It also describes the technical details of MRI techniques to help the clinician understand the most important elements of CMR in assessing and managing their patients. In creating the book, the editors have assembled a world-renowned panel of contributors to review the use of CMR in CHD and make it accessible to those working in the field and to those who use the information derived from CMR in their clinical practice.

This book was released on 2012-12-06 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is with pleasure that I write this foreword for the book "Magnetic Resonance Imaging in Coronary Artery Disease", edited by Dr. van der Wall and Dr. de Roos. I am pleased for two reasons. Firstly, as chairman of the Scientific Board of the Interuniversity Cardiology Institute of the Netherlands (ICIN), because ever since the technique became available for use in medicine and biology our Institute has tried and succeeded to promote the introduction and dev- opment of magnetic resonance imaging in cardiology in the Netherlands. ICIN was the first cardiological institute on the European continent to purchase its own nuclear magnetic resonance spectroscope for the study of myocardial metabolism. Secondly, because I have always been infatuated with this noninvasive technique that can produce cardiac images without ionic radiation and at the same time allows for the study of myocardial metabolism as well. And even more so because nuclear magnetic resonance imaging in medicine is one of the shining examples of medical progress as a result of breakthrough discoveries in physics and chemistry.

Download or read book The Heart in Rheumatic Autoimmune and Inflammatory Diseases written by Udi Nussinovitch and published by Academic Press. This book was released on 2017-02-10 with total page 768 pages. Available in PDF, EPUB and Kindle. Book excerpt: The prevalence of autoimmune diseases and rheumatic conditions is constantly increasing. Autoimmune diseases affect approximately 7-10% of the population of the United States, while more than 50,000,000 American adults suffer from some type of arthritis. The Heart in Rheumatic, Autoimmune and Inflammatory Diseases examines the complex mechanisms relating to cardiac diseases from a pathophysiological and clinical point of view. Autoimmune rheumatic diseases can affect the coronary vessels, myocardium, pericardium, heart valves and the conduction system. The diagnosis of these unique cardiac complications necessitates medical awareness and a high index of suspicion. Increased risk of advanced atherosclerosis plays a pivotal role in the development of cardiac diseases in systemic, rheumatic and autoimmune illnesses. Yet, other complex immune medicated mechanisms may contribute to the pathogenesis. Patients' optimal care requires coordination between the primary caregiver, the rheumatologist, immunologist and cardiologist. Screening for cardiovascular risk factors, recognition of high-risk patients and identification of subclinical cardiac conditions are of great importance. Moreover, regulation of inflammation, as well as abnormal immune responses and the initiation of early treatments should be the focus of patient management. A continuous attempt to identify novel therapeutic targets and change the natural history of the underlying disease and its cardiac manifestations is in progress. The book aims at providing the readers with a state of the art collection of up to date information regarding clinically important topics based on experts' perspectives. This book was a result of an extended coordinated collaboration of one-hundred and fifty-four distinguished scientists from thirty-one countries around the globe. A review of common, as well as unusual (yet clinically significant) medical cardiac complications of prevalent rheumatic, autoimmune and inflammatory diseases. Focuses on aspects of pathophysiological processes, clinical presentations, screening tests, prognostic implications and novel therapeutic approaches. Presents an up-to-date “level of evidence” and “strengths of recommendations” for suggested therapies and reviews all randomized clinical trials, meta-analyses and other supporting published clinical findings.

Download or read book Myocardial Viability written by Vasken Dilsizian and published by Wiley-Blackwell. This book was released on 2000-02-10 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite remarkable advances in the understanding and management of impaired left ventricular function (LVF) and related coronary disease, the prevalence of heart failure in the U.S. and the resulting death rates have almost tripled in the past 3 decades. New understanding of the relationships between the myocardium and LVF demonstrate a direct correlation between myocardial viability and improved patient survival. Because of this, myocardial viability is now a major investigative area in contemporary cardiology, one that holds significant clinical and prognostic relevance. Authored by physicians of international renown, the book brings together various disciplines affecting myocardial viability, with five main sections providing an introduction and comprehensive review of: basic concepts and mechanisms; vascular biology and cellular physiology; advances in functional imaging; and perfusion, metabolism and cell membrane integrity. New concepts, such as stunning and hibernation, are clarified, and subsequent novel diagnostic and therapeutic strategies are described. New and sophisticated examination techniques are also presented, as well as advances in instrumentation and imaging techniques, which may result in improved use of resources and enhanced efficiency of health care delivery. This monograph will serve as a reference source for those interested in the field of myocardial viability, and hopefully improve understanding between investigators from various disciplines. Clinical cardiologists, physicians, and nurses in the field, as well as radiologists, vascular surgeons, reperfusionists, cellular biologists and physiologists, and students will all find material of interest in this book.
