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.

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.

Just a very few years after Edler and Hertz had described the clinical use of M-mode echocardiographyl Satomura reported the application of Dop 2 pler ultrasound to the study of cardiac function. Yet Doppler ultrasound has been integrated into diagnostic practice in cardiology much more slowly than conventional (M-mode and two-dimensional) echocardiogra phy. Now, however, tremendous growth in the interest of clinicians in the diagnostic use of Doppler ultrasound can be observed and may in fact be due to the recent advent of color flow imaging. The reason for this growth may be that this method makes it possible to directly visualize the blood flow in the cardiovascular system in cross-sectional views. Moreover, the results are reproducible and much easier to understand than the older mapping techniques using a single-gate Doppler. In its short existence many different names have been used to describe this method, for instance, color Doppler, color flow imaging, real-time two-dimen sional Doppler echocardiography, and Doppler flow imaging. This diver sity reflects the large interest that many researchers have shown in this method. The technical development of color blood flow imaging (CBFI) - as this method will be called in this book - has not yet reached a universally accepted standard of performance in cardiology. Despite this state of flux and the uncertainty about future developments, I think it is justified to dedicate an entire book to this fascinating method.

In a relatively short period of time two-dimensional echo cardiography has become the most important non-invasive diagnostic tool in the daily practice of a pediatric cardiologist who predominantly deals with congenital structural heart disease in neonates and infants. Consequently, one-dimensional M-mode echocardiography has lost most of its importance particularly in this field. Therefore, an atlas showing exclusively two-dimensional echocardiograms of the most common and some less frequently occurring malformations appeared to be a useful addition to the existing literature. The confinement to two dimensional imaging alone allowed an elaborate presentation of the various defects with more than 200 selected still frames and many additional explanatory drawings and diagrams. The material was collected from patients who were referred to the Department of Pediatric Cardiology of the Wilhelmina University Children's Hospital in Utrecht during a period of about 2 years. The two-dimensional echocardiographic findings were correlated with cardiac catheterization data and/or surgical procedures and/or post mortem investigations. The necessary echocardiographic equipment was aquired with financial aid from the Dutch Heart Foundation. We are indebted to Mrs. J. W. Wetselaar for her outstanding artwork. We also thank P. D. Woltema and F. J. van Waert for the photographic reproductions, Jacomine Bosma for preparing and type-setting the entire manuscript and Dr. N. Middleton for critically reading the English text. G.
