Abstract
This extensively revised second edition traces the development of the basic concepts in cardiovascular physiology in light of the accumulated experimental and clinical evidence. It considers the early embryonic circulation, where blood circulation suggests the existence of a motive force, tightly coupled to the metabolic demands of the tissues. It proposes that rather than being an organ of propulsion, the heart, serves as an organ of control, generating pressure by rhythmically impeding blood flow. New and expanded chapters cover the arterial pulse, circulation in the upright posture, microcirculation and functional heart morphology. Heart and Circulation offers a new perspective for deeper understanding of the human cardiovascular system. It is therefore a thought-provoking resource for cardiologists, cardiac surgeons and trainees interested in models of human circulation.

What drives the circulation? In this comprehensive review of existing circulation models, the conventional view that the heart is a pressure-propulsion pump is challenged. The existing models fail to explain an increasing number of observed circulatory phenomena. A unifying circulation model is proposed in which the blood, responding to metabolic demands of the tissues, is the primary regulator of cardiac output. This new model arises from accumulated clinical and experimental evidence. The hea…

Abstract
What drives the circulation? In this comprehensive review of existing circulation models, the conventional view that the heart is a pressure-propulsion pump is challenged. The existing models fail to explain an increasing number of observed circulatory phenomena. A unifying circulation model is proposed in which the blood, responding to metabolic demands of the tissues, is the primary regulator of cardiac output. This new model arises from accumulated clinical and experimental evidence. The heart, rather than being an organ of blood propulsion, assumes a secondary role and generates pressure by impeding the flow of blood. This is supported by examples from the fields of early embryonic circulation, comparative phylogeny, functional morphology, exercise physiology and a range of clinical scenarios. The Heart and Circulation: An Integrative Model offers a paradigm shift in the understanding of circulatory phenomena. It will become a valuable resource for all those clinicians, researchers, educators and students who, having been confronted with the paradox of the circulation, are looking for a broader interpretation.

Abstract
This book, now in its revised and updated third edition, is designed to meet the needs of both novice and experienced sonographers by offering a superbly illustrated, wide-ranging account of the use of ultrasonography in the diagnosis of vascular diseases. Each of the main chapters is subdivided into text and atlas sections. The text part documents the relevant ultrasound anatomy, explains the examination procedure, specifies the indications for diagnostic ultrasound, describes normal and pathological findings, and considers the clinical impact of the examination. The atlas part presents a rich compilation of case material illustrating the typical ultrasound findings for both common vascular diseases and rarer conditions that are nevertheless significant for the vascular surgeon and angiologist. The new edition places special emphasis on the role of hemodynamics in clinical symptomatology, and the use of spectral analysis techniques is fully explained. Particular attention is also drawn to the sources of potential discrepancies between investigative methods, including different ultrasound studies, the role of contrast-enhanced studies, and the therapeutic consequences of pathological findings. Helpful algorithms are included to illustrate how targeted ultrasound diagnosis often permits therapeutic planning without the need for further imaging techniques.

Vortex formation has received much attention over the past few years. Vortices occur in nature wherever propulsive flow exists; from erupting volcanoes to the ones generated by squid and jellyfish to propel them. There has been particular interest in the wide variety of vortices that develop in the cardiovascular system, particularly in the cardiac chambers and in large arteries. These vortices play fundamental roles in the normal physiology and provide proper balance between blood motion and s…

Abstract
Vortex formation has received much attention over the past few years. Vortices occur in nature wherever propulsive flow exists; from erupting volcanoes to the ones generated by squid and jellyfish to propel them. There has been particular interest in the wide variety of vortices that develop in the cardiovascular system, particularly in the cardiac chambers and in large arteries. These vortices play fundamental roles in the normal physiology and provide proper balance between blood motion and stresses on the surrounding tissues. In contrast, formation of unnatural vortices may alter the momentum transfer in the blood flow and increase energy dissipation. Vortex Formation in the Cardiovascular System reviews the current knowledge of vortex formation, from the basic physics to cardiac physiology. There is a particular focus on the formation of vortices at different locations inside the heart, the effect of cardiac devices and surgery on vortex formation, fluid dynamics of the artificial heart valves and ventricular assist devices. The Authors have translated physical, mathematical and engineering concepts related to vortex formation into a clinical perspective with the objective to advance cardiovascular patient care. This book therefore represents a comprehensive and valuable resource for those involved in the field of cardiology and cardiovascular physiology, cardiovascular surgeons, interventional cardiologists, medical bioengineers and researchers in fluid mechanics.
