Book excerpt: In recent years there has been an increasing interest in quantitative analysis of coronary cineangiograms and already for a longer time of left ventricular cin eangiograms. The needfor quantitationofcoronary arterialdimensions has been stimulated by the introduction ofnew therapeutic procedures in the catheteriza tionlaboratory, suchas the balloon dilatationtechnique (PTCA) and thromboly tic therapy, by the need to study the vasoactive responses of pharmaceutical agents, and also by the desire to study the progressive nature ofcoronary artery disease with the ultimate goal to find ways to bring a halt to the progression of coronary atherosclerosis or even achieve regression of the disease. Parallel with these clinical developments, rapid technical developments in computerarchitect ures and semiconductor memories have made it possible to digitize and store cineframesor selected portions thereof in image processors and to analyze these pictorial data quantitatively at affordable prices. More than 15 years of research have been directed by various groups towards the semi- or fully-automated delineation of the left ventricular boundaries on a frame-to-frame basis. Yet not a single system with fully-automated capability is commercially available. In the mean time many different left ventricular wall motion models have been developed, again with little consensuson which model is to be preferred as no golden standard exists.

Book Synopsis Progress in quantitative coronary arteriography by : Johan H. C. Reiber
Download or read book Progress in quantitative coronary arteriography written by Johan H. C. Reiber and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the fifth volume in this series on quantitative coronary arteriography (QCA) published over the last nine years. Research and applications in this exciting, field are covered in a total of 26 chapters by world renowned experts. This book is subdivided into a total of 6 parts, each emphasizing the latest progress in these respective fields. In Part One a comprehensive overview is given of the current knowledge and research in endothelial function, which is of eminent importance for the further understanding of the pathophysiology of coronary artery disease in patients. Fortunately, the use of QCA tools is not limited anymore to leading research institutes; over the last several years these tools have been installed in many cardiology centers world wide. To understand the current possibili ties, limitations and future expectations of QCA, several relevant topics are presented in Part Two. First of all, the questions about why and how QCA systems should be validated both at the development site and at the appli cation sites, and whether data from different vendors and core laboratories can be pooled, are discussed. As the X-ray cardiovascular world steadily moves into the digital imaging era, differences and similarities between the conventional cinefilm and the modern digital approaches are presented. Cur rently. the widespread use of digital imaging is still hindered by the lack of proper archival and exchange media. Requirements and possible solutions for this problem are handled in this section as well.
Book Synopsis State of the Art in Quantitative Coronary Arteriography by : Johan H. C. Reiber
Download or read book State of the Art in Quantitative Coronary Arteriography written by Johan H. C. Reiber and published by Springer. This book was released on 1986-09-30 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past twenty years, technical advances in coronary arteriography have contributed to our understanding of the pathophysiologic aspects and natural history of coronary artery disease. Probably more than 700. 000 coronary arterio grams are performed annually throughout the world. Usually, these arteriograms are interpreted visually to determine the morphologic extent and severity of coronary artery disease. These subjective determinations, which are hampered . by relatively large intra- and interobserver variations, are used as a basis for critically important therapeutic decisions: Which arteries are to be revascular ized, which lesions are suitable for coronary bypass surgery or for percutaneous coronary angioplasty? To improve on this clinical decision making, on the treat ment and follow-up of such patients, new, objective and reproducible techniques for the assessment of the extent and severity of coronary artery disease, both in terms of anatomy and functional significance of the lesions, must be made widely available. With such new procedures and technologies the efficacy of new thera peutic procedures, the effects of vasodilating and constricting drugs, and the results of long-term studies on the regression and progression of atherosclerotic plaque can be determined in an objective and cost-effective manner.

Book Synopsis Quantitative Coronary Angiography in Clinical Practice by : P.W. Serruys
Download or read book Quantitative Coronary Angiography in Clinical Practice written by P.W. Serruys and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 754 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantitative coronary angiography has become an invaluable tool for the interventional cardiologist, providing objective and reproducible measurements of coronary artery dimensions, which can be used to study progression or regression of coronary atherosclerosis, as well as the immediate and long term effects of percutaneous interventions. Until recently, this powerful imaging technology was confined to a small number of so-called high level institutions. Fortunately, with the development of digital cardiac imaging equipment and adaptation of cine-angiographically based computer software for on-line use in the catheterization room, quantitative coronary angiography is now available to all interventionalists. This book is a timely guide for the impending QCA user, providing practical as well as theoretical and scientific information. A comprehensive evaluation of the clinical usefulness of QCA is covered, from the fundamental principles through experimental validation studies, application to clinical trials of a wide range of pharmacological and interventional therapies in the full spectrum of clinical presentation of coronary disease syndromes, evaluation of the therapeutic efficacy of various new devices for coronary intervention, together with extensive presentation of its physiological, functional and anatomical correlations, by comparison with other intracoronary measurement and imaging techniques. In addition, evolving theories and concepts in the ever topical `restenosis phenomenon' after percutaneous intervention, based on serial QCA studies, are presented and discussed and a potentially unifying methodological approach to further study of this ubiquitous problem is offered. This book, thanks to the collaboration of many experts in the field of intracoronary imaging and measurement, provides stimulating, interesting and practical information, both for the academic scientist and practising clinician.

This book was released on 2012-12-06 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this fourth book in the series on quantitative coronary arteriography (QCA) with the earlier three volumes published in 1986, 1988 and 1991, the latest developments in this exciting field are covered. Both the methodolog ical and clinical application aspects of these advances are presented in a comprehensive manner in a total of 37 chapters by world renowned experts. The book is subdivided into a total of eight parts, beginning with the more methodological issues, such as QCA and other modalities (3 chapters), cine film versus digital arteriography (3 chapters), quality control in QCA (4 chapters), and coronary blood flow and flow reserve (3 chapters). Since QCA has been well established as the technique for the assessment of regression and progression in atherosclerotic disease, and of restenosis after recanaliz ation procedures, major clinical trials in both groups are described extensively by their principal investigators in a total of 11 chapters. In addition, the QCA results after the application of various recanalization techniques are presented in another eight chapters. In the last part the experiences with various intracoronary prostheses with the emphasis on QCA are discussed in five chapters. This large increase in application oriented chapters means that QCA is well alive and gaining momentum. Although the accuracy and precision of the analytical methods steadily improve with the increasing complexity of the algorithms, there is still always the human factor involved in these processes in terms of frame selection, segment definition, etc.

This book was released on 2012-12-06 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Foreword by Eric J. Topol In the past five years, interventional cardiology has entered a new era of evaluating percutaneous transcatheter technologies to treat coronary artery disease and prevent restenosis. Cardiologists attempting to follow this new and exciting field may easily be confused by the growth and expansion of new devices, the technical details relevant to each device and enthusiastic claims of success. This monograph is a comprehensive and objective assessment of restenosis from the perspective of these new technologies including stenting, atherectomy, rotational abrasion and lasers, written by innovators and pioneers. The international breadth of experience is reflected in the summary of experiences from both sides of the Atlantic, at times with conflicting observations and results which in itself is valuable, given the diverse experience to date. In addition to the lucid summaries of the early and late results of these new devices, important issues in the methodology of restenosis research are addressed, including limitations of quantitative coronary arteriography in evaluating the new devices and important advances in alternatives to arteriography such as intravascular imaging. As a whole, this monograph is exceptionally worthwhile owing to its complete, up-to-date, balanced and visionary elements. There is no question that the new coronary device era has ushered in some excitement, and some despair. This book serves a pivotal purpose by weaving so many new concepts together, establishing the groundwork for further development of mechanical approaches to limit restenosis. I heartily recommend this text to all interventional cardiologists interested in practical and research aspects of restenosis.
Book Synopsis New Developments in Quantitative Coronary Arteriography by : Johan H. C. Reiber
Download or read book New Developments in Quantitative Coronary Arteriography written by Johan H. C. Reiber and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are few techniques that have influenced therapeutic strategies in modem cardiology to a similar extent as coronary arteriography. Bypass surgery as well as transluminal coronary angioplasty would not have been possible without coronary angiography serving as a 'midwife' in their evolu tion. Despite the widespread and long-standing use in clinical practice, however, the interpretation of coronary angiograms has not changed very much since the early days. Most angiogr~s are still reviewed in a visual and semi-quantitative and thus often very subjective way. In the face of an almost exploding field for interventional catheterization including thrombolysis, balloon dilatation, and other rapidly evolving techniques for transluminal revascularization or recanalization, a more detailed and quantitative analysis of coronary arteriograms is urgently required. In addition to the delineation of coronary morphology, we need dynamic and functional information about flow and perfusion to understand the physiological significance of anatomic abnormalities. Coronary arteriography contains and can provide most of this information. With the application of appropriate techniques, it can be made available in the catheterization laboratory even during the patient's investiga tion, thus facilitating and improving clinical decision making. Objective and reproducible analysis will furthermore enhance our understanding about the pathophysiology of coronary disease.

Available in PDF, EPUB and Kindle. Book excerpt: This is the first monograph to focus exclusively on coronary radiology. It is particularly timely, given that the emergence of computed tomography and magnetic resonance imaging, coupled with improvements in both hard- and software, has made reproducible non-invasive coronary imaging a practical reality. A wide range of topics is addressed, including: quantitative angiography, intravascular and quantitative ultrasound, multislice and electron beam computed tomography, magnetic resonance coronary angiography and use of the coronary calcium score as an independent risk factor. All of the latest developments, such as non-invasive intracoronary thrombus imaging, are covered. Particular care has been taken to consider the common questions confronted in asymptomatic patients. The text is supported by high-quality color images of the coronary and cardiac anatomy.

This book was released on 2012-12-06 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is indeed ironical that in the absence of a complete knowledge of Pathophysiology, clinical cardiologists are left with no choice but to do the best they can to help the patient with the armamentarium of drugs at their disposal. But nothing could be further from truth than to treat the diagnosed end point of a disease process without a full understanding of its patho physiology. This point was eloquently made by Dr. Arnold Katz in his Presidential Address (Chapter 1) at the 8th Annual Meeting of the American Section of the International Society for Heart Research held in Winnipeg, Canada, July 8-11, 1986. This volume represents a part of the scientific proceedings of this Meeting. From a reading of this treatise it will become evident that discoveries of newer scientific facts as well as a better understanding of pathophysiology are continuously influencing/ improving our therapeutic approaches in modern medicine. In this book, latest biochemical, physiological and pharmacological findings on different experimental models such as Myocaridal hypertrophy, Hypertension and heart failure, Diabetes, Cardio myopathies and Cardiac function in shock are described by internationally recognised experts. Hopefully information presented here will provide another building block to the edifice of Science of Cardiology which we all are trying to create.

Download or read book Pharmacological Aspects of Heart Disease written by R. E. Beamish and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of heart and artery disease as a cause of death and disability is difficult to exaggerate: it causes over half of all deaths in the western world and now accounts for one-quarter of deaths in the entire world. This appalling incidence persists in spite of commendable progress in treatment and prevention, particularly in the last two or three decades. Deaths from coronary disease have decreased by a third in the past twenty years and stroke has decreased by a half in the same period. This remarkable improvement, saving thousands of lives per year, has come about due to changes in life style (low fat diet, control of high blood pressure, less smoking and more exercise) and progress in treatment (more effective drugs, coronary care units, pacemakers, and cardiac surgery). Progress in understanding the pathophysiologic and pharn,acologic mechanisms operative in heart disease have been paramount in the development of more rational and more effective therapy. Dramatic and spectacular surgical treatments have fired the public imagination. Bypass surgery is commonplace and results in complete or considerable relief of symptoms in the majority of patients operated upon.
Book Synopsis Catheter Ablation of Cardiac Arrhythmias by : Melvin Scheinman
Download or read book Catheter Ablation of Cardiac Arrhythmias written by Melvin Scheinman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of catheter ablation has grown In a rather helter-skelter fashion. Ablative techniques were applied in patients before basic bioelectric and cellular electrophysiologic effects were fully defined. Since the introduction of this technique into clinical medicine in 1982, happily, a wealth of basic information has become available, and it was thought prudent to summarize existing data in the form of a text. The purpose of this text is to provide for a concise summary of both the basic and clinical experiences to date. It was simply not possible to include chapters from many workers who have made outstanding contributions in this area. For this, I offer my profound apolo gies. I do wish, however, to acknowledge the outstanding work of Drs. Bharati and Lev who provided us with a sound understanding of the histolo gic effects of various energy delivery systems. Their seminal observations allowed us to bring this technique to clinical fruition.
