This is the first book to present an overview of the exciting new cardiac imaging technique of tissue Doppler echocardiography (TDE). In order to understand the background of this technique, it is necessary to compare the physical properties of blood, which reflects ultrasound poorly but moves with high velocity (up to 150 cm/s) with those of the myocar dium, which reflects ultrasound strongly but moves with low velocity (less than 10 cm/s). In tissue Doppler imaging, existing Doppler technology has been modified to bypass the high-pass filter and enhance calculation of low velocities, thus enabling selective visualization of the myocardium rather than of the blood. Because the color Doppler tissue images are super imposed on the conventional two-dimensional ultrasound images, this technique is known as TDE. Following a brief introduction, the history of ultrasound and Doppler imaging is presented. It is now about 150 years since the death of Christian Doppler, who described the "Doppler" effect, and more than 100 years since Pierre Curie discovered the piezoelectric effects of crystals. TDE was developed by Nobuo Yamazaki and Yoshitaka Mine at the Medi cal Engineering Laboratory, Toshiba Corporation, Tochigi, Japan. En gineers involved in the development of the technique have provided important technical information, which the reader will find an invaluable background to potential applications ofTDE.

The introduction of quantitative Doppler echocardiography gave rise to explo sive interest in the application of this method in clinical cardiology. However, before cardiologists could fully validate its clinical utility, they were confronted with a further development, namely color-coded Doppler flow imaging. This new technique allows a comprehensive study of the direction, velocity, uniformity and timing of intracardiac blood flow, while simultaneously revealing cardiac struc tures and their movement. 'Color Doppler' facilitates the diagnosis of a variety of cardiac conditions, and an overwhelming amount of information is available at any instant. Interpretation of these fascinating images requires a substantial experience and theoretical background. This monograph updates the application of color Doppler to both congenital and acquired heart disease. The work comprises 15 chapters written by authorities in the field, each of whom presents his most recent experience in the field. In addition, further advantages in the clinical use of pulsed and continuous wave Doppler in pediatric and adult cardiol ogy are presented. This book contains, of course, many color plates. 1.

Basic Concepts in Doppler Echocardiography The objective of this textbook is to offer a detailed yet concise overview of the various applications of Doppler echocardiography. The fundamental principles of pulsed mode, continuous mode, and color flow mapping are fully explained as well as the clinical applications of each modality in the evaluation of various cardiac pathologies. A copious amount of figures and illustrations is included so that the reader is able to follow the discussions in the text by referring to the appropriate case studies. The emphasis of this book is focused upon the practical Doppler examination. The sections on theoretical considerations are therefore brief but comprehensive, while the didactic sections concentrate upon how to perform and interpret the clinical examination. The instrumentation of the Doppler system is also discussed so that the physician or technologist can acquire a basic understanding of how the Doppler system actually functions. CONTRmUTORS Bjorn AJ.

For almost 40 years, a small but intense group of cardiovascular investigators have evaluated cardiac performance by measuring the mass, velocity, and acceleration of blood ejected from the left ventricle. These studies reveal that energy is transferred from ventricle to blood very early in systole, and that the left ventricle is charac terized as an impulse generator. Recent explosive developments in Doppler echocar diography have allowed study of the energetics of ventricular contraction through noninvasive acceleration, velocity, and volumetric flow measurements. Compared against reference standards of ejection fraction, dP/dt, and instantaneous pressure gradient across the aortic valve, Doppler acceleration and velocity measurements are highly sensitive to changes in ventricular performance. Most patients seeking cardiovascular care present with coronary artery disease as a chief concern. This book focuses upon identification of coronary disease presence and severity through the evaluation of left ventricular Doppler ejection responses to stress loading. Chapters I through 4 detail basic research on the dynamics of left ventricular ejection in ischemic and nonischemic animal models. Chapters 5 through 13 present clinical correlates of changes in the Doppler systolic ejection pulse during exercise and under pharmacologic stress loading. Angiographic anatomy, thallium perfusion defects, and radionuclear ejection fraction responses serve as reference standards. Chapters 14, 15 and 16 address applications of Doppler echocardiography during the stresses of brief coronary occlusion, myocar dial infarction and post infarction recovery, while chapters 17 and 20 illustrate applications of stress Doppler techniques in valvular heart disease.

This book covers the full range of Doppler echocardiography in infants and children, documenting the wide variety of potential findings with the aid of a wealth of high‐quality images. The imaging features of more than 20 conditions on conventional two‐dimensional echocardiography, pulsed wave, continuous wave and color Doppler imaging are described and depicted, drawing attention to differential diagnostic criteria and other issues of importance in everyday clinical practice. Each condition is individually addressed, covering all relevant aspects, and helpful information is also provided on the normal examination. The book is supplemented by more than 500 videos demonstrating typical findings of two-dimensional and color Doppler echocardiography. Special chapters focus on the differential diagnosis of cyanotic infants and echocardiography specifically for the neonatologist. The authors' aim in compiling this book is to equip the reader with the knowledge required in order to employ Doppler echocardiography optimally and to interpret findings confidently and correctly. Doppler Echocardiography in Infancy and Childhood will be an invaluable reference for echocardiographers, pediatricians, neonatologists, and pediatric and general radiologists.
