Book Description
This book introduces magnetic bearings--mechatronic devices that produce contact-free electromagnetic force to support a load, such as a moving train or a spinning rotor. Compared to traditional bearings, magnetic bearings offer several advantages: no friction, low heat generation, no required lubrication, quiet operation, and fast and stable rotation. For these reasons, magnetic bearings have been used in rotary ventricular assist devices (VADs) to increase design life, reduce or eliminate material wear and bearing maintenance, as well as to increase biocompatibility by eliminating high fluid stresses and heat generation, both of which are associated with hemolysis, platelet activation and aggregation, and thrombus growth. The book covers the principles of these bearings, how they are used in integrated control and electronics systems, and useful information on several major brands of current assist devices.

Book Description
A comprehensive history of the development of artificial hearts in the United States. Artificial hearts are seductive devices. Their promissory nature as a cure for heart failure aligned neatly with the twentieth-century American medical community’s view of the body as an entity of replacement parts. In Artificial Hearts, Shelley McKellar traces the controversial history of this imperfect technology beginning in the 1950s and leading up to the present day. McKellar profiles generations of researchers and devices as she traces the heart’s development and clinical use. She situates the events of Dr. Michael DeBakey and Dr. Denton Cooley’s professional fall-out after the first artificial heart implant case in 1969, as well as the 1982–83 Jarvik-7 heart implant case of Barney Clark, within a larger historical trajectory. She explores how some individuals—like former US Vice President Dick Cheney—affected the public profile of this technology by choosing to be implanted with artificial hearts. Finally, she explains the varied physical experiences, both negative and positive, of numerous artificial heart recipients. McKellar argues that desirability—rather than the feasibility or practicality of artificial hearts—drove the invention of the device. Technical challenges and unsettling clinical experiences produced an ambivalence toward its continued development by many researchers, clinicians, politicians, bioethicists, and the public. But the potential and promise of the artificial heart offset this ambivalence, influencing how success was characterized and by whom. Packed with larger-than-life characters—from dedicated and ardent scientists to feuding Texas surgeons and brave patients—this book is a fascinating case study that speaks to questions of expectations, limitations, and uncertainty in a high-technology medical world.

Book Description
The increasing pace of advances in cardiology throughout the last few decades has fundamentally altered the natural course of heart patients. In the last few years, available therapies have been revolutionized completely by new transcatheter therapeutic approaches, novel ventricular assist devices, and new drugs. Also, molecular biology and genetics have a rapidly growing impact on cardiovascular diseases, enabling the field of regenerative medicine to become increasingly closer to routine clinical implementation. Emerging Technologies for Heart Diseases was conceived to cover the recent extensive literature on current and novel therapeutic options for cardiac patients. The first volume is dedicated to heart failure and valvular disorders, and the second covers myocardial ischemia and arrhythmias. The clinical topic is addressed in several chapters divided according to the therapeutic approach (mechanical or electrical device-based, or cell and gene-based). Each of the 46 chapters focuses on clinically available solutions, new therapies currently under evaluation in clinical trials, promising preclinical technologies, and emerging concepts and innovations that have not yet been tested in a preclinical model. Also, the book discusses future challenges and opportunities for clinical implementation. Lessons learned from abandoned experimental practices are also covered, giving the readers the widest possible perspective of current therapeutic dilemmas. Overall, this textbook was designed for physicians who want to stay up-to-date with current therapies and those of the future, for biomedical companies, and for those who wish to broaden their knowledge of new cardiovascular therapeutic options. - Provides a comprehensive review of the latest therapeutic developments for heart failure, valvular disorders, myocardial ischemia and arrhythmias, and their clinical implications - Written by both specialists in the field and established researchers, it delivers a review of emerging medical technologies and presents insight into their therapeutic promise - Chapters are arranged according to disease pathogeneses and relevance and include coverage of the mechanical, electrophysiological, and biological approaches for the management of patients with heart failure should be replaced with heart failure and valvular disorders
