Book Description
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.

Book Description
In this book, the importance and value of accurately assessing coronary stenosis morphology is reviewed, including recent thoughts regarding the pathogenetic mechanisms ascribed to angiographically assessed morphology, several new and potentially more accurate means of determining plaque composition and its relationship to stenosis morphology, and the latest hypotheses regarding interventional device selection. Each chapter has been written by acknowledged experts in the area, who have contributed significantly to that body of knowledge and are considered opinion leaders nationally and internationally. Each chapter contains the basic `how-to' of that technique, the manner in which it is best utilized or considered, and the limitations that must be taken into account in its application. In some chapters, the authors address guidelines regarding image acquisition and analysis to minimize the variations resulting from the potential error sources. It is hoped that this work will lead to technological developments, improved performance, and more rational clinical utilization.

Book Description
Written by a distinguished pioneer in the history and development of coronary angioscopic techniques, Coronary Angioscopy is the first and only book to systematically describe the present status of percutaneous coronary angioscopy and cardioscopy. Cardiologists and other interested physicians will value its clear explanations of the pathophysiology of coronary artery diseases, as well as the author's advice and instruction on the mastering of cutting-edge coronary angioscopic and cardioscopic techniques. The book's scope includes a review of the dramatic developments that have brought so much change in such a short time. From the introduction of the flexible endoscope in the late 1940s to the creation of the fiberscope by the author in the late 1990s, the tools and techniques described within are presented with well-earned authority. Composed of three parts (addressing the topics of coronary angioscopy, cardioscopy, and a discussion of possible future applications of both techniques), the book's large, well-designed, atlas-style format and extensive use of color illustrations (160 of 250 figures are in color) make it a particularly effective resource. In addition, it provides information on new findings, techniques and devices, such as the cardioscopic observation of coronary microvessels from the cardiac chambers themselves, many of which are not previously reported.

Book Description
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.

Book Description
In recent years, there has been increasing interest in the clinical applications of coronary angiography techniques. Coronary MRA can be instrumental in the evaluation of congenital coronary artery anomalies, however, the complexity of advanced MR pulse sequences and strategies may be overwhelming to many. Coronary MR Angiography demystifies the art of coronary MRA by providing a text in plain language with clearly illustrated imaging steps and protocols. Designed to bridge the gap between radiology and cardiology, it is written for physicians and scientists planning to incorporate this technique into their research or practice.

Book Description
This book presents a thorough review of coronary angioscopy, ranging from instructions on its use to the latest advances. Starting with the structure and fundamental principles of angioscopy, it shows readers how to apply the image to comprehensive care of coronary-artery patients. Plentiful color photos and illustrations will enable readers to investigate and classify plaques and thrombi and to evaluate coronary stent- and drug-based therapies. The authors are leading researchers on angioscopy. This book offers the perfect guide not only for new clinicians but also for cardiologists who have already adopted this technique for medical examination and treatment. Angioscopy is a unique medical technique for visualizing the interior of blood vessels and helps physicians not only to diagnose the pathology but also to measure the effectiveness of Percutaneous coronary intervention (PCI) or antiarteriosclerotic drugs. Furthermore, the recently developed molecular angioscopy approach allows us to observe Low-density lipoprotein (LDL) oxide, collagen, and macrophages, and is rapidly growing in importance.

Book Description
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.

Book Description
In the past two decades a number of studies have shown that abnormalities in the function and structure of coronary microcirculation can be detected in several cardiovascular diseases. On the basis of the clinical setting in which it occurs, coronary microvascular dysfunction (CMD) can be classified into four types: CMD in the absence of any other cardiac disease; CMD in myocardial diseases; CMD in obstructive epicardial coronary artery disease; and iatrogenic CMD. In some instances CMD represents an epiphenomenon, whereas in others it represents an important marker of risk or may contribute to the pathogenesis of myocardial ischemia, thus becoming a possible therapeutic target. This book provides an update on coronary physiology and a systematic assessment of microvascular abnormalities in cardiovascular diseases, in the hope that it will assist clinicians in prevention, detection and management of CMD in their everyday activity.
