Book Description
According to Schopenhauer problems are usually passing through three stages: - in the first stage they are ignored or just smiled at, - in the second stage they are fought, and in the third stage they are considered to be self-evident, just taken for granted. Whereas digital subtraction angiography (DSA) has obviously reached stage three of that scale, i.e. routine use in radiology, digital angiocardiography, in particular imaging the heart and coronary circulation, is still on its way to the final goal: the filmless heart catheterization laboratory for all invasive and interventional procedures. A few pioneers have already completely abandoned the conventional cine coronary and angiocardiographic technique, others - as we do -still combine both digital and conventional methods in clinical routine, but most cardiol ogists up till now stay sceptically aside. We hope that at least some of the articles published in this volume may convince more and more cardiologists that digital imaging procedures are the method of choice, in particular if quantitative assessment of the anatomical or functional status of the cardiovascular system is required (pre- and post operations or pre-and post-interventions). Such a critical control of all therapeutic procedures, be it by surgical, catheter-or medical 'interventions', is indeed an urgent and widely under estimated or neglected requirement.

Book Description
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.

Book Description
by JULIEN IE HOFFMAN One of the earliest coronary physiologists was Scaramucci who, in 1695, postu lated that during systole the contracting myocardium inhibited coronary blood flow. Since then, the many contributions that have been made to our knowledge of the coronary circulation can be arbitrarily divided into three phases based on advances in technical methods. The early phase of research into the coronary circulation, done with great difficulty with crude methods, may be regarded as ending in the 1940s, and it included major discoveries made by such well known investigators as Georg von Anrep, Ernest Starling, Carl Wiggers, and Louis Katz, who formulated much of our basic understanding of the field. After 1940, the field of coronary physiology entered a new phase when instruments for high fidelity registration of coronary flow and pressure became available. This era was domi nated by Donald Gregg who combined careful attention to the function of these instruments (some of which he helped to develop) with an extraordinary ability to discern mechanisms from apparently minor changes in coronary flow and pressure patterns. His book 'The Coronary Circulation in Health and Disease' set a new standard in the field. After 1960, techniques for measuring regional myocardial blood flow became available, and enabled a large group of eminent investigators to make major advances in understanding the physiology and pathophysiology of myocardial blood flow.

Book Description
In June 1989, a third conference concentrating on the progress in quantita tive coronary angiography and related techniques was held in Rotterdam, again very successful as the two preceding events in 1985 and 1987. Tech nical as well as clinical aspects of digital and digitized coronarography, morphometry, parametric imaging and functional quantification of the human coronary circulation were presented and discussed by prominent exponents of those groups who have been active in this particular field for many years. This book contains the chapters representing the lectures held by leading experts during the symposium that update the knowledge currently available, including most recent aspects in angioscopy and intravascular ultrasound imaging. It also includes a historical review on the development of angiogra phic techniques from the very early days on to our times given by one of the pioneers in heart catheterization and angiography, Dr. Kurt Amplatz. Those who had the chance to listen to his talk, will surely remember his impressive, humorous lecture as one of the highlights of this meeting.

Book Description
Occult atherosclerotic diseases impose great challenges in the cardiovascular practice. Although their pathology is not much different from that of the overt group of diseases, the clinical approach to their diagnoses remains a puzzle. This has mainly emerged as a result of the problems faced in trying to pick up the vulnerable subjects from among the general public. More definitive candidates to be evaluated are those belonging to one of the high risk groups. There are no statistical figures available on the incidence of occult atherosclerotic disease in the "non risky" general public and this is definitely an area that needs further investigation. Atherosclerotic disease whether they are in the cerebral, coronary, renal or lower limb arteries are theoretically interrelated because the basic patho logical changes are usually similar. However there still remain some differ ences which are mainly due to variation in the flow pattern in the arteries. Thus it will be important clinically and from the management point of view to investigate for the presence of occult disease in other arteries if an atherosclerotic disease in a certain artery has been discovered. This approach is of a great significance especially from the preventive point of view in order to avoid catastrophic events which may have resulted from pathology in the other region.

Book Description
An international meeting of experts on Cardiovascular Imaging by Ultrasound was held in Aachen from 26-27 April, 1991. It provided new and interesting insights into what has already been achieved in ultrasound-based cardiovascular diagnosis and therapy and what will be introduced in clinical practice in the near future. Since the introduction of ultrasound in clinical practice in 1984 there has been no other physical principle that has added and will continue to add so much to clinical diagnosis and therapy. Echocardiography, once established as a non-invasive diagnostic tool, is increasingly becoming an invasive technique for cardiovascular imaging. This book contains the edited contributions from 38 scientists and engineers from all over the world who presented the most up-to-date findings on 2-dimensional echocardiography, different Doppler modalities, contrast and stress echocardiography and the different modalities of transesophageal echocardiography, including mono-, bi- and multiplane TEE, as well as pulsed and CW-Doppler application via TEE. Exciting and promising developments are discussed in the field of intravascular ultrasound, tissue characterization, ultrasound ablation, ultrasound-based 3-dimensional reconstruction of the heart, and high frequency Doppler analysis.
