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 is the seventh edition of a long-selling book (first edition 1991) that was translated into Italian, French, Chinese, Portuguese, Spanish, English. In the last ten years, stress echocardiography has exploded in its breadth and variety of applications. From a one-fits-all approach (wall motion by 2D-echo in the patient with known or suspected coronary artery disease), the field has progressed to an omnivorous, next-generation laboratory employing a variety of technologies (from M-Mode to 2D, from pulsed, continuous, color and tissue Doppler to lung ultrasound) on patients covering the entire spectrum of severity (from elite athletes to patients with end-stage heart failure) and ages (from children with congenital heart disease to the elderly with aortic stenosis). This new edition is enriched with over 300 figures, 150 tables and video-clips. In a societal and economic climate of increasing pressure for appropriate, justified and optimized imaging, stress echocardiography offers the great advantages of being radiation-free, relatively low cost, with minimal environmental impact, and with a staggering versatility: we can get more (information) with less (cost and risk). The volume will be a tremendous aid to current best practices for all health operators who intend to use stress echocardiography and ultrasound for diagnosis and guidance of optimal management in their patients.

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.

Coronary flow reserve is an important functional parameter to understand the pathophysiology of coronary circulation. Coronary flow reserve measurement is used to assess epicardial coronary stenoses or to examine the integrity of microvascular circulation. An appreciation of coronary physiology is an integral part of clinical decision-making for cardiologists treating patients with coronary artery disease. The pioneering research efforts of Dr Lance Gould, who explored the relationship between the anatomic severity of a stenosis and its flow resistance (59;60) , have been transferred to clinical practice (94; 194). In the absence of stenosis in epicardial coronary artery, the coronary flow reserve may be decreased when coronary microvascular circulation is compromised by arterial hypertension with or without left ventricular hypertrophy, diabetes mellitus, hypercholesterolemia, or other diseases. Several techniques have been established for measuring coronary flow reserve. However, these techniques are either invasive (intracoronary Doppler flow wire), highly expensive and scarcely available (Positron Emission Tomography - PET) or semi-invasive and causing patient discomfort (transesophageal Doppler echocardiography), thus their clinical use is limited. Because of the clinical importance of coronary flow reserve there is a need for a simple, noninvasive, repeatable and inexpensive tool capable of this functional evaluation. This monograph focuses on the assessment of coronary flow reserve using transthoracic Doppler echocardiography - the technique fulfilling the above-mentioned criteria. Transthoracic Doppler echocardiography has become a popular tool evolving from a research to diagnostic technique applied in everyday practice.

This book provides essential information for using quantitative Doppler echocardiography in routine clinical cardiological practice. It translates complex concepts and formulations into practical, easily understood evaluations that will allow any properly equipped echocardiographic laboratory to enjoy the rewards of "quantitative" cardiac Doppler. The book is organized so that physical-physiological mechanisms and methods are presented first and then their practical applications are emphasized for various anatomical sites in the cardiovascular system. Chapter summaries are provided to allow readers to rapidly review the most pertinent information contained within each chapterr. The book's first four chapters deal basically with the fundamental mechanisms that affect clinical evaluations, such as basic formulations, pressure gradients, pressure half-times, and time velocity integrals. Remaining chapters discuss the anatomical areas of the heart and great vessels. Appendix A presents "technical tips" relative to the performance of the Doppler examination. Appendix B provides helpful blank "worksheets" and valvular and hemodynamic abnormalities. Appendix C presents an easy reference to normal and abnormal echo-Doppler values. Both cardiology students and practicing professionals will find this book indispensable for help with upgrading the level of noninvasive diagnostic capabilities in their Doppler echocardiographic labs.
