Download or read book Mechanical Circulatory Support written by R. Hetzer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: After decades of laboratory investigations mechanical circulatory support for the failing heart has entered the clinical arena. Today, a growing number of patients with progressive myocardial failure awaiting cardiac transplantation is successfully bridged to transplantation with ventricular assist devices. The proceedings of the "Mechanical Circulatory Support"-meeting, held in Berlin, October 21-22, 1995, present new aspects of mechanical circulatory support, recent experience with MCS in newborns and children using specially developed small devices, and the results of long-term mechanical assistance. The ability of the myocardium to recover under pressure de-loading and reduced workload is discussed. All these topics open up new perspectives for the use of mechanical circulatory support, not only as a bridge to transplantation, but also as a definitive approach for treating patients with end-stage heart failure. Some of these concepts may even provide real alternatives to heart transplantation, these being sorely needed in light of the severe donor organ shortage. Regulatory as well as ethical aspects of the extended use of mechanical circulatory support systems and new technical developments in the field are discussed by internationally distinguished experts.

Download or read book Expanding the Performance Envelope of the Total Artificial Heart Physiological Characterization Development of a Heart Failure Model And Evaluation Tool for Mechanical Circulatory Support Devices written by Jessica Renee Crosby and published by . This book was released on 2014 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heart failure (HF) affects an estimated 5.8 million Americans, accounting for near 250,000 deaths each year. With shortages in available donor hearts, mechanical circulatory support (MCS) has emerged as a life-saving treatment for advanced stage HF. With growth in MCS use, a clinical and developmental need has emerged for a standard characterization and evaluation platform that may be utilized for inter-device comparison and system training. The goal of this research was to harness SynCardia's total artificial heart (TAH) to meet this need. We first sought to characterize the TAH in modern physiological terms - i.e. hemodynamics and pressure-volume loops. We then developed a model of HF using the TAH and mock circulatory system operating in a reduced output mode. We demonstrated that MCS devices could be incorporated and evaluated within the HF model. Finally, we characterized the operational envelope of SynCardia's Freedom (portable), Driver operating against varying loading conditions. Our results describe the hemodynamic envelope of the TAH. Uniquely, the TAH was found not to operate with time-varying elastance, to be insensitive to variations in afterload up to at least 135 mmHg mean aortic pressure, and exhibit Starling-like behavior. After transitioning the setup to mimic heart failure conditions, left atrial pressure and left ventricular pressure were noted to be elevated, aortic flow was reduced, sensitivity to afterload was increased, and Starling-like behavior was blunted, consistent with human heart failure. The system was then configured to allow ready addition of ventricular assist devices, which upon placement in the flow circuit resulted in restoration of hemodynamics to normal. Lastly, we demonstrated that the Freedom Driver is capable of overcoming systolic pressures of 200 mmHg as an upper driving limit. Understanding the physiology and hemodynamics of MCS devices is vital for proper use, future device development, and operator training. Characterization of the TAH affords insight into the functional parameters that govern artificial heart behavior providing perspective on differences compared to the human heart. The use of the system as a heart failure model has the potential to serve as a valuable research and teaching tool to foster safe MCS device use.

Download or read book Mechanical Circulatory Support in End stage Heart Failure written by Andrea Montalto and published by . This book was released on 2017 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a detailed practical guide to the use of ventricular assist devices and total artificial hearts to provide mechanical circulatory support (MCS) in patients with end-stage heart failure. It explains why MCS may be indicated, which patients require MCS, when and how to implant ventricular assist devices or a total artificial heart, and how to avoid potential complications of MCS. Management throughout the period of care is described, from preimplantation to follow-up, and both typical and atypical cases are discussed. The text features numerous helpful tips and tricks relating to surgical and nonsurgical management and is supported by a wealth of high-quality illustrations that document the preoperative evaluation and implantation techniques. Heart transplantation remains the gold standard for the treatment of patients suffering from end-stage heart failure, but the shortage of donors has led to an increase in the use of MCS. This book will assist all physicians, and especially cardiologists and anesthesiologists, who are involved in the care of these patients.

Download or read book The Transplant Imaginary written by Lesley A. Sharp and published by Univ of California Press. This book was released on 2014 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Transplant Imaginary, author Lesley Sharp explores the extraordinarily surgically successful realm of organ transplantation, which is plagued worldwide by the scarcity of donated human parts, a quandary that generates ongoing debates over the marketing of organs as patients die waiting for replacements. These widespread anxieties within and beyond medicine over organ scarcity inspire seemingly futuristic trajectories in other fields. Especially prominent, longstanding, and promising domains include xenotransplantation, or efforts to cull fleshy organs from animals for human use, and bioengineering, a field peopled with “tinkerers” intent on designing implantable mechanical devices, where the heart is of special interest. Scarcity, suffering, and sacrifice are pervasive and, seemingly, inescapable themes that frame the transplant imaginary. Xenotransplant experts and bioengineers at work in labs in five Anglophone countries share a marked determination to eliminate scarcity and human suffering, certain that their efforts might one day altogether eliminate any need for parts of human origin. A premise that drives Sharp’s compelling ethnographic project is that high-stakes experimentation inspires moral thinking, informing scientists’ determination to redirect the surgical trajectory of transplantation and, ultimately, alter the integrity of the human form.
