Book Description
The last five years have witnessed an increasing interest in the subject of transmyocardial laser revascularization (TMR) as illustrated by the number of abstracts presented at the meetings of the American Heart Association and the American College of Cardiology (Figure). The ideas and concepts associated with this particular method of myocardial revascularization have changed dramatically over even this short period of time. The original premise of "de-evolving" mammalian hearts to recreate a reptilian-like myocardial circulation by making multiple channels through the myocardium has been almost (but perhaps not quite) completely dismissed. Now, the most popular notion is that there is an angiogenic response to myocardial channel making. It is this development of new blood vessels that is thought to be responsible for the apparent improvements in symptoms and blood flow. Along the way, the idea that a channel could stay open and allow blood to flow directly from the ventricular chamber has found little support. Rather than directly explore all of these issues and merely duplicate previously published articles, our aim was to take a novel approach: that is, to step back from these arguments and provide perspective from the vantage point of distance. In the case of trans myocardial revascularization, distance comes both in terms of history and in terms of methodology and knowledge from other fields of research. Historically, innovative methods of myocardial revascularization are by no means uncommon. The first two chapters deal with this historical' perspective.

Book Description
The Social Security Administration (SSA) uses a screening tool called the Listing of Impairments to identify claimants who are so severely impaired that they cannot work at all and thus immediately qualify for benefits. In this report, the IOM makes several recommendations for improving SSA's capacity to determine disability benefits more quickly and efficiently using the Listings.

Book Description
With a vast background of personal experience and a review of more than 300 references, Dr. Segesser has written a book to close the gap between the theory and practice of coronary artery revascularization. In particular, he shows the possibilities and limitations of internal mammary artery grafting in this surgical procedure. The chapters guide you to a thorough understanding of the subject, from anatomy and pathology, to experimental studies and the history of first surgical attempts, to clinical application and results. The discussion of long-term follow-up, complications and re-operations point to areas of success as well as subjects for future research. The details provided here about operative strategies and their outcomes give the cardiovascular surgical team important feedback about present practices which will help lead to improved clinical results.

Book Description
Despite remarkable advances in the understanding and management of impaired left ventricular function (LVF) and related coronary disease, the prevalence of heart failure in the U.S. and the resulting death rates have almost tripled in the past 3 decades. New understanding of the relationships between the myocardium and LVF demonstrate a direct correlation between myocardial viability and improved patient survival. Because of this, myocardial viability is now a major investigative area in contemporary cardiology, one that holds significant clinical and prognostic relevance. Authored by physicians of international renown, the book brings together various disciplines affecting myocardial viability, with five main sections providing an introduction and comprehensive review of: basic concepts and mechanisms; vascular biology and cellular physiology; advances in functional imaging; and perfusion, metabolism and cell membrane integrity. New concepts, such as stunning and hibernation, are clarified, and subsequent novel diagnostic and therapeutic strategies are described. New and sophisticated examination techniques are also presented, as well as advances in instrumentation and imaging techniques, which may result in improved use of resources and enhanced efficiency of health care delivery. This monograph will serve as a reference source for those interested in the field of myocardial viability, and hopefully improve understanding between investigators from various disciplines. Clinical cardiologists, physicians, and nurses in the field, as well as radiologists, vascular surgeons, reperfusionists, cellular biologists and physiologists, and students will all find material of interest in this book.

Book Description
This book provides an overview of the etiology of coronary artery disease and focuses on the main therapies and drug interventions currently available. It highlights drug pharmacology and therapeutic challenges, with a special emphasis on the underlying principles of available therapeutics and the on-going development of drugs for coronary artery disease. The book is divided into eight chapters, the first of which describes the classical mechanism of coronary artery disease and its clinical presentations. Chapter 2 lists the principles of and related evidence on the prevention and treatment of coronary artery disease. This includes diet and lifestyle management, and guidelines for the treatment of acute coronary syndrome and stable coronary artery disease. In turn, Chapter 3 describes revascularization treatments, covering percutaneous coronary interventions, coronary artery bypass grafts and thrombolysis. This chapter also addresses the main therapeutic challenges. The following chapters provide an overview of three major categories of coronary artery disease drugs, which target thrombosis (Chapter 4), lipid metabolism (Chapter 5), and hypertension (Chapter 6). Heart failure constitutes the major health burden in the late stage of coronary artery disease; accordingly, current heart failure therapeutics and related drug pharmacology are described in Chapter 7. In closing, Chapter 8 provides a summary of on-going clinical trials for coronary artery disease drug development and discusses a number of promising areas in which intensive research into new therapeutics is being pursued. Given its scope, the book will be of interest to clinicians, medical students and research scientists, as well as to pharmaceutical professionals who are seeking new therapies and drugs for coronary artery disease and related disorders.

Book Description
Chronic total occlusions (CTO) are common, and found in approximately one third of patients with significant coronary artery disease who undergo angiography. Over the past 20 years, CTO lesions have represented the most difficult anatomy for treatment — with lower success rates and higher complication rates. Chronic Total Occlusions provides interventionalists insight into the world of CTOs with introductory chapters that describe the pathology and indications of CTOs along with a review of clinical trials. Imaging modalities including CT angiography, magnetic navigation wire, and IVUS guided recanalization of CTO are also introduced, together with information on new wires technology and devices for CTOs. With numerous illustrations of these devices, technologies, and strategies to improve the CTO success rate, this clinical guide, headed up by Ron Waksman, will prove to be the ideal companion for interventional cardiologists and cardiac surgeons who are required to perform angioplasty and coronary stenting.
