The cardiac system represents one of the most exciting challenges to human ingenuity. Critical to our survival, it consists of a tantalizing array of interacting phenomena, from ionic transport, membrane channels and receptors through cellular metabolism, energy production to fiber mechanics, microcirculation, electrical activation to the global, clinically observed, function, which is measured by pressure, volume, coronary flow, heart rate, shape changes and responds to imposed loads and pharmaceutical challenges. It is a complex interdisciplinary system requiring the joint efforts of the life sciences, the exact sciences, engineering and technology to understand and control the pathologies involved. The Henry Goldberg Workshops were set up to address these multivariable, multidisciplinary challenges. Briefly, our goals are: To encourage international cooperation and foster interdisciplinary interaction between scientists from the different areas of cardiology; to relate microscale cellular phenomena to the global, clinically manifested cardiac function; to relate conceptual modeling and quantitative analysis to experimental and clinical data; to gain an integrated view of the various interacting parameters, identify missing links, catalyze new questions, and lead to better understanding of the cardiac system. The outstanding success of past workshops has encouraged their continuation. The first Henry Goldberg Workshop, held in Haifa in 1984, introduced the concept of interaction between mechanics, electrical activation, perfusion and metabolism, emphasizing imaging in the clinical environment. The second Workshop, in 1985, discussed the same parameters with a slant towards the control aspects.

This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

The characteristics of the basic elements and the cardiac functions will be highlighted in this volume. In their contributions, the authors concentrate on the analysis and integration of the interactions of the micro-scale cellular elements, as well as of the macro-scale phenomena and their effects on the function of the cardiovascular system. The general goals of the cardiac workshop of which this volume is the proceedings were to (1) foster interdisciplinary interaction between leading world scientists and clinical cardiologists so as to identify "black holes" and catalyze new research ideas; (2) relate basic micro-scale, molecular, and subcellular phenomena to the clinically manifested cardiac performance; (3) apply conceptual modeling and quantitative analysis to better explore, describe, and understand cardiac physiology; (4) interpret available clinical data and design new revealing experiments; and (5) enhance international cooperation in the search for the secrets of life and their implications in cardiac pathophysiology.

The objective of this book is to provide the researcher and clinician with the recent developments in the analysis and assessment of cardiovascular func tion. The chapters are organized into sections that correspond with the various anatomical levels of the cardiovascular system. To a large extent, recent focus on the cardiovascular system function has been directed at the molecular level to the near exclusion of the tissue and organ function. While this may be useful in developing new therapeutic drugs, it does not aid the cardiologist or surgeon, who routinely deal with patient symptoms. This book integrates the micro-level and organ-level function so that new infor mation may be assimilated into the cardiovascular system as a whole. Within each section, the chapters have been arranged to progress from recent theoretical developments, to experimental research, and finally to clinical applications. This approach facilitates the timely transfer of infor mation from basic research to the clinic. The strength of the analytical approach will be evident to the reader. The theoretical analysis offers guidance to experimental design and, in some cases, offers solutions where measurements are as yet unattainable. In moving from newly attained knowledge to clinical practice, this book emphasizes the noninvasive meth in the future as technological advances ods. Such methods are desirable occur and the trend towards early preventive diagnosis is sought. What follows are highlights of new developments covered in each section of the book.

This book gathers together contributions from internationally renowned authors in the field of cardiovascular systems and provides crucial insight into the importance of sex- and gender-concepts during the analysis of patient data. This innovative title is the first to offer the elements necessary to consider sex-related properties in both clinical and basic studies regarding the heart and circulation on multiscale levels (i.e. molecular, cellular, electrophysiologically, neuroendocrine, immunoregulatory, organ, allometric, and modeling). Observed differences at (ultra)cellular and organ level are quantified, with focus on clinical relevance and implications for diagnosis and patient management. Since the cardiovascular system is of vital importance for all tissues, Sex-Specific Analysis of Cardiovascular Function is an essential source of information for clinicians, biologists, and biomedical investigators. The wide spectrum of differences described in this book will also act as an eye-opener and serve as a handbook for students, teachers, scientists and practitioners.

This outstanding resource provides a comprehensive guide to intracardiac blood flow phenomena and cardiac hemodynamics, including the developmental history, theoretical frameworks, computational fluid dynamics, and practical applications for clinical cardiology, cardiac imaging and embryology. It is not a mere compilation of the most up-to-date scientific data and relevant concepts. Rather, it is an integrated educational means to developing pluridisciplinary background, knowledge, and understanding. Such understanding allows an appreciation of the crucial, albeit heretofore generally unappreciated, importance of intracardiac blood flow phenomena in a host of multifaceted functional and morphogenetic cardiac adaptations. The book includes over 400 figures, which were prepared by the author and form a vital part of the pedagogy. It is organized in three parts. Part I, Fundamentals of Intracardiac Flows and Their Measurement, provides comprehensive background from many disciplines that are necessary for a deep and broad understanding and appreciation of intracardiac blood flow phenomena. Such indispensable background spans several chapters and covers necessary mathematics, a brief history of the evolution of ideas and methodological approaches that are relevant to cardiac fluid dynamics and imaging, a qualitative introduction to fluid dynamic stability theory, chapters on physics and fluid dynamics of unsteady blood flows and an intuitive introduction to various kinds of relevant vortical fluid motions. Part II, Visualization of Intracardiac Blood Flows: Methodologies, Frameworks and Insights, is devoted to pluridisciplinary approaches to the visualization of intracardiac blood flows. It encompasses chapters on 3-D real-time and "live 3-D" echocardiography and Doppler echocardiography, CT tomographic scanning modalities, including multidetector spiral/helical dataset acquisitions, MRI and cardiac MRA, including phase contrast velocity mapping (PCVM), etc. An entire chapter is devoted to the understanding of post processing exploration techniques and the display of tomographic data, including "slice-and-dice" 3-D techniques and cine-MRI. Part II also encompasses an intuitive introduction to CFD as it pertains to intracardiac blood flow simulations, followed--in separate chapters--by conceptually rich treatments of the computational fluid dynamics of ejection and of diastolic filling. An entire chapter is devoted to fluid dynamic epigenetic factors in cardiogenesis and pre- and postnatal cardiac remodeling, and another to clinical and basic science perspectives, and their implications for emerging research frontiers. Part III contains an Appendix presenting technical aspects of the method of predetermined boundary motion, "PBM," developed at Duke University by the author and his collaborators.

After yet another decade of leaming, experimenting, and inves tigating since my first book, Arterial System Dynamics, the many new medical breakthroughs and technological advances have inspired me to write this book to bridge the gap between basic research and clinical applications. The application of physical principles and quantitative approaches to the understanding of the arterial circulation and its interactions with the heart in normal and diseased conditions form the basis of The Arterial Circulation. Knowledge of the physiology and rheology of arteries, as well as all of their structural-functional corre lates, is a necessary prerequisite to the proper hemodynamic interpretatiqn of pressure-flow relations and the pulsatile transmis sion characteristics in different arteries. The natural coupling and interactions of the heart, the coronary circulation, and the arterial system necessitate analysis of alterations to global functioning. Modeling provides a tool for isolating and predicting parameter changes and is employed throughout the book. Experimental data are provided for model validations, and also for more realistic interpretations. Techniques and new methods for clinical hemo dynamic measurement and diagnosis are included to help the reader un derstand the physical principles underlying such abnormal cardiovascular functions as hypertension, stenosis, and myocardial ischemia. The progressive changes in vascular properties during aging are also discussed. Modem approaches utilizing computer mode ling and allomery are presented with selected examples, such as combined hypertension and aortic valve stenosis, and ventricular hypertrophy.

Projections for advances in medical and biological technology will transform medical care and treatment. This in great part is due to the result of the interaction and collaboration between medical sciences and engineering. These advances will result in substantial progress in health care and in the quality of life of the population. Frequently however, the implications of technologies in terms of increasing recurrent costs, additional required support services, change in medical practice and training needs are underestimated. As a result, the widespread irrational use of te- nologies leads to a wastage of scarce resources and weakens health systems performance. To avoid such problems, a syst- atic and effective Health Technology System must be developed and introduced, requiring the support and commitment of decision makers of all levels of the health system. The MediTech2009 conference aims to provide a special opportunity for the Romanian professionals involved in basic - search, R&D, industry and medical applications to exchange their know-how and build up collaboration in one of the most human field of science and techniques. The conference is intended to be an international forum for researchers and practit- ners interested in the advance in, and applications of biomedical engineering to exchange the latest research results and ideas in the areas covered by the topics (and not only!). We believe the reader will find the proceedings an impressive document of progress to date in this rapidly changing field.
