This book is intended as a guide for all cardiologists who are interested in coronary imaging and physiology, a sound understanding of which is vital for the optimal performance of appropriate coronary interventions. The basics of each relevant modality are presented, with clear explanation of clinical utility and evaluation of the evidence regarding clinical outcomes. All technical methods are described in detail, and the text is complemented by numerous helpful tables and illustrations. The effectiveness of intravascular coronary imaging in improving clinical outcomes is proven, and it is widely used for this purpose. Two modalities for intravascular coronary imaging are available in clinical practice: intravascular ultrasound (IVUS) and optical coherence tomography (OCT). For coronary physiology, the pressure wire-derived fractional flow reserve (FFR) provides information on the functional status of coronary trees. This technique and its clinical applications receive particular attention in the book, which also looks beyond FFR to FFR-CT, a method using computational fluid dynamics, and to invasive assessment of the microcirculation.

Research centering on blood flow in the heart continues to hold an important position, especially since a better understanding of the subject may help reduce the incidence of coronary arterial disease and heart attacks. This book summarizes recent advances in the field; it is the product of fruitful cooperation among international scientists who met in Japan in May, 1990 to discuss the regulation of coronary blood flow.

Since the introduction of coronary angiography, a key technique in understanding coronary artery disease, a number of paradigms regarding its study and interpretation have taken place. Following an emphasis on improved angiographic and subsequent intracoronary imaging techniques, functional assessment of coronary circulation has demonstrated to have major implications for diagnosis and treatment of coronary artery disease. Fractional flow reserve, a pressure derived index of stenosis severity, constitutes the best example of the current importance of physiological assessment in clinical practice. However, the acceptance of FFR by cardiologists contrasts with important voids in knowledge on the basic principles of coronary physiology and of other available techniques that, as an alternative to FFR, allow a more comprehensive assessment of coronary circulation. This is particularly noticeable in the assessment of microcirculation, an unavoidable compartment of coronary circulation that is frequently affected in acute coronary syndromes of in the presence of cardiovascular risk factors or non-coronary heart disease. A deeper understanding of the relationship between epicardial vessel and microcirculatory involvement has started with the advent of newer imaging techniques like invasive optical coherence tomography, and non-invasive CT and NMR techniques. This book aims to be an indispensable tool for clinicians and researches in the field of coronary artery disease. It provides a balanced, comprehensive review of anatomy, physiology and available techniques, discusses both the diagnosis of epicardial vessel and microcirculatory disease, the impact of different diseases at different levels of coronary circulation, and the best way to address a separate or combined assessment of different levels of coronary circulation. ​

The Social Security Administration (SSA) uses a screening tool called the Listing of Impairments to identify claimants who are so severely impaired that they cannot work at all and thus immediately qualify for benefits. In this report, the IOM makes several recommendations for improving SSA's capacity to determine disability benefits more quickly and efficiently using the Listings.

Atherosclerotic Plaque Characterization Methods Based on Coronary Imaging provides a complete review of computer methods for atherosclerotic plaque reconstruction and characterization. The authors, with their expertise from biomedical engineering, computer science, and cardiology, offer a holistic view. The focus of the book is on the presentation of major imaging techniques, including their limitations. It includes details on the mechanical characterization and properties of plaques and appropriate constitutive models to describe the mechanical behavior of plaques. The authors explore the challenges of using multiple coronary imaging technologies, and provide the pros and cons of invasive vs. non-invasive techniques. Methods for plaque characterization and 3D reconstruction of coronary arteries using IVUS, OCT, and CT images are described. This book will help readers study new trends in image processing analysis and plaque characterization, implement automated plaque characterization methodologies, understand coronary imaging drawbacks, and comprehend 3 dimensional coronary artery and plaque reconstruction methods. - Describes the multimodality imaging techniques that are commonly used in the diagnosis of arterial diseases, including intravascular ultrasound, optical coherence tomography, angiography, computed tomography angiography, and magnetic resonance angiography - Discusses in-depth the computational methods which can be used for the detection of different plaque types - Explores plaque in 3D reconstruction methods and plaque modeling approaches

Cardiologists must answer three important questions when evaluating and treating patients with a coronary artery stenosis. As a physiologist: "What is the effect of this stenosis on coronary blood flow and myocardial function?"; as a clinician: " Is this lesion responsible for the patient's symptoms?"; and finally as an interventionalist: "Will revascularization of this artery improve the patient?" Fundamentally, the answer to these questions can be given to a large extent by measuring coronary pressure. That is the rationale of writing this book. 1. 1 Historical overview. Andreas Gruentzig and most interventional cardiologists in the early days of PTCA, had the intuitive feeling that pressure measurements could help to establish the severity of a coronary stenosis and to monitor the progress and result of a coronary intervention. At that time, measuring coronary pressure by the balloon catheter was part of a standard procedure. A residual transstenotic gradient of less than 15 mmHg was generally considered as a good result. Later, however, it turned out that measuring these (resting) gradients with balloon catheters was inaccurate an only had a limited prognostic value. Moreover, because there was no consistent theory to correlate pressure measurements to blood flow, the interest in measuring coronary pressures faded and disappeared almost completely with the introduction of new balloon catheters not intended for pressure measurement.

Coronary Heart Disease: Clinical, Pathological, Imaging, and Molecular Profiles presents a comprehensive picture of ischemic heart disease for practitioners, students, and investigators dealing with the varied facets of this complex subject. Individual chapters introduce the anatomy of the coronary blood vessels and cardiac development, while others consider current imaging modalities utilized for ischemic heart disease, including stress echo, nuclear diagnostic tests, non-invasive coronary artery imaging, and coronary angiography. Imaging chapters provide key clinical information on techniques and indications, and include examples of both normal and abnormal patterns. The principle thrust of the book concerns coronary atherosclerosis, the pathology of which is presented in conjunction with the results of anatomic, non-invasive imaging and angiographic studies. Related chapters cover atherogenesis, presenting new insights into the pathophysiology of the vulnerable plaque, the role of progenitor cells in vascular injury, inflammation and atherogenesis, and the genomics of vascular remodeling. Additional topics covered include angina pectoris, acute coronary syndromes, healed myocardial infarction and congestive heart failure, catheter-based and surgical revascularization, and surgical treatment of myocardial infarction and its sequelae. With contributions from a diverse group of internationally-known physicians with broad experience in the diagnosis and treatment of coronary heart disease, this book will be a valuable resource for practitioners in clinical cardiology, thoracic surgery, pathology, and cardiovascular molecular research, as well as for students in training.
