The notion of being able to engineer complete organs has inspired an entire generation of researchers. While recent years have brought significant progress in regenerative medicine and tissue engineering, the immense challenges encountered when trying to engineer an entire organ have to be acknowledged. Despite a good understanding of cell phenotypes, cellular niches and cell-to-biomaterial interactions, the formation of tissues composed of multiple cells remains highly challenging. Only a step-by-step approach will allow the future production of a living tissue construct ready for implantation and to augment organ function. In this book, expert authors present the current state of this approach. It offers a concise overview and serves as a great starting point for anyone interested in the application of tissue engineering or regenerative medicine for organ engineering. Each chapter contains a short overview including physiological and pathological changes as well as the current clinical need. The potential cell sources and suitable biomaterials for each organ type are discussed and possibilities to produce organ-like structures are illustrated. The ultimate goal is for the generated small tissues to unfold their full potential in vivo and to serve as a native tissue equivalent. By integrating and evolving, these implants will form functional tissue in-vivo. This book discusses the desired outcome by focusing on well-defined functional readouts. Each chapter addresses the status of clinical translations and closes with the discussion of current bottlenecks and an outlook for the coming years. A successful regenerative medicine approach could solve organ shortage by providing biological substitutes for clinical use - clearly, this merits a collaborative effort.

This book covers the latest research development in heart valve biomechanics and bioengineering, with an emphasis on novel experimentation, computational simulation, and applications in heart valve bioengineering. The most current research accomplishments are covered in detail, including novel concepts in valvular viscoelasticity, fibril/molecular mechanisms of tissue behavior, fibril kinematics-based constitutive models, mechano-interaction of valvular interstitial and endothelial cells, biomechanical behavior of acellular valves and tissue engineered valves, novel bioreactor designs, biomechanics of transcatheter valves, and 3D heart valve printing. This is an ideal book for biomedical engineers, biomechanics, surgeons, clinicians, business managers in the biomedical industry, graduate and undergraduate students studying biomedical engineering, and medical students.

As the proportion of older adults increases in the U.S. population, the prevalence of degenerative heart valve disease is also increasing. Calcific aortic stenosis (narrowing) and ischemic and degenerative mitral regurgitation (leakage) are the most common valvular disorders in adults aged 70 years and older. For patients with severe valve disease, heart valve replacement involving open heart surgery can improve functional status and quality of life. A variety of conventional mechanical and bioprosthetic heart valves are readily available. However, some individuals are considered too high risk for open heart surgery. These patients may benefit from a less invasive procedure. Percutaneous heart valve replacement is a relatively new interventional procedure involving the insertion of an artificial heart valve using a catheter, rather than through open heart surgery. The portal of entry is typically either via the femoral vein or artery, or directly through the myocardium via the apical region of the heart. An expandable prosthetic heart valve is delivered and deployed at the site of the diseased native valve. The percutaneous heart valve replacement procedure usually takes less time to perform and is less invasive than open heart surgery. The Agency for Healthcare Research and Quality (AHRQ) has commissioned this Technical Brief to: Describe the types of conventional and percutaneous heart valves now in use or in development and their theoretical advantages and disadvantages for different patient populations; Describe the literature comparing various types of conventional heart valves in adults and determine whether a systematic review of this literature is feasible and needed; Describe the literature evaluating percutaneous heart valves in adults, including the patient populations and major outcomes studied to date; Describe implantation techniques for percutaneous heart valves and the factors associated with surgery or setting that may impact outcomes. The research team further clarified and refined the overall research objectives and the key questions. The key questions addressed are as follows: Question 1. What are the different types of heart valves in use and in development (including tissue, mechanical, and percutaneous valves)? a. What are the existing or potential U.S. Food and Drug Administration (FDA) indications for each valve (patient characteristics, etc.)? b. What are the theoretical advantages and disadvantages of different valves for different patient populations? Question 2. From a systematic literature scan of studies on different types of tissue and mechanical valves, describe the types of comparative studies, including basic study design, size of study, length of followup, and outcomes assessed. This literature scan will provide data to determine if a systematic review of this literature is possible and needed, and to provide needed context for understanding the evaluation and development of percutaneous heart valves. Question 3. From a systematic literature scan of studies on different types of percutaneous heart valves, provide a synthesis of the following variables: a. Number for each type of valve. b. Type of studies—comparative and non-comparative randomized controlled trials (RCTs), non-randomized controlled clinical trials, case series, etc. c. Variables associated with surgery (implantation technique), setting, etc. d. Size of studies/length of followup. e. Patient population/concurrent and prior treatments. f. Hemodynamic success rates reported. g. Harms reported. Question 4. What are the variables associated with surgery or setting that may impact outcomes for percutaneous heart valves? a. What are the different implantation techniques (i.e., position of implantation, delivery, and axis techniques)? What is the evidence of success (i.e., absence of narrowing and regurgitation) and harms? i. For percutaneous aortic valves. ii. For percutaneous mitral valves.

We are in the midst of a digital revolution - until recently, the majority of appliances used in everyday life have been developed with analogue technology. Now, either at home or out and about, we are surrounded by digital technology such as digital 'film', audio systems, computers and telephones. From the late 1940s until the 1970s, analogue technology was a genuine alternative to digital, and the two competing technologies ran parallel with each other. During this period, a community of engineers, scientists, academics and businessmen continued to develop and promote the analogue computer. At the height of the Cold War, this community and its technology met with considerable success in meeting the urgent demand for high speed computing for use in the design and simulation of rockets, aircraft and manned space vehicles. The Analogue Alternative tracks the development, commercialisation and ultimate decline of the electronic analogue computer in the USA and Britain. It examines the roles played by technical, economic and cultural factors in the competition between the alternative technologies, but more importantly, James Small demonstrates that non-technical factors, such as the role of 'military enterprise' and the working practices of analogue engineers, have been the most crucial in analogue's demise.^l This book will be of interest to students of the history and sociology of science and technology, particularly computing. It will also be relevant to those interested in technical change and innovation, and the study of scientific cultures.
