Cardiovascular disease is the major cause of morbidity and mortality worldwide. While the past 40 years have brought major progress in cardiac valve repair and replacement, there remain large patient populations that do not receive such therapies. This, in turn, implies a great need for future basic, applied, and clinical research and, ultimately, therapeutic developments. Heart Valves is a state-of-the-art handbook dedicated to: 1) cardiac valve anatomy, 2) models for testing and research methods; 3) clinical trials; and 4) clinical needs and applications.

Despite the significant decline in heart disease mortaht>' rates over the last 25 years, heart failure has remained a significant problem. We are now confronted with large numbers of terminally ill patients for whom conventional therapies for heart failure have been exhausted and for whom repeated hospital visits are necessary. There now is a major thrust towards a management strategy which embraces a comprehensive approach including vigorous preventive measures and earlier surgical interventions. This book outlines the major surgical options for the treatment of heart failure and brings together a very broad base of opinions with contributions from several outstanding individuals. With the improved knowledge and techniques to control rejection, transplantation has become the central pillar in the surgical management of this group of patients. Unfortunately, because of limited donor supply the teclmique cannot be applied to large numbers of patients. A great deal of excitement, however, exists in the potential for xenotransplantation as a supplement to homotransplantation. The use of cardiac assist devices has become a reality with several hundred LVADS and BiVADS implanted throughout the world and cardiac replacement with total artificial hearts continues to be used successfully as a bridge to transplantation. We are on the thieshold of the broad application of assist devices to provide prolonged relief of heart failure and restore patients to an ambulatoiy home environment and hopefully return to the work force in significant numbers.

While a surgeon many decades agotreated diseases from headtotoe, this concept has evolved, and today some degree of specialization is the rule worldwide. In many countries various boards for sub-specializations are designed, and after a broad training in general surgery, many young surgeons move on further into a specific field. Knowledge of anatomy and precise surgical technique remain the foundation of high quality surgery. A knowledgeable surgeon, equipped with excellent theore- cal and clinical skills, will only be accomplished when he or she masters the - erative techniques of the practice of surgery. The legacy of an academic surgeon or a surgical teacher relies in great part onthe transmission of his or her surgical abilities. Significant influence on the development in esophageal surgery arises from the surgical understanding of the anatomical and functional structures of the esophagus as well as the ongoing developments in the multidisciplinary m- agement in this challenging field of surgery. In bringing forth this atlas, we were motivated by the desire to create a comp- hensive and educational atlas on esophageal diseases, emphasizing all details of pathophysiologies, diagnostic strategies, pre- and postoperative management, and operative techniques covering minimally invasive and open procedures ranging fromstraightforward tomore complex procedures.

This book offers a historical account of the development of the On-X carbon mechanical heart valve, discussing the steps involved in developing the materials, and describes how the design of the valve has evolved over the years. It explores both the scientific and corporate problems researchers have encountered over the years in the journey of making a mechanical heart valve. The chapters provide a detailed description of the design of the mechanical leaflet-based prosthetic valve, with a particular focus on blood flow characteristics. This book includes an overview of the state-of-the-art in the chemistry and physics of carbon, and compiles the advances in carbon-based technology and its applications in cardiac and thoracic surgery. This is an ideal book for bioengineers working on the chemistry and physics of carbon, and other professionals involved with cardiac and thoracic surgery.

Fundamentals of Congenital Minimally Invasive Cardiac Surgery is a first of its kind, fully-illustrated guide that is solely dedicated to the most diffused congenital minimally invasive cardiac surgery procedures. It provides detailed, step-by-step descriptions of surgical maneuvers to underline each aspect of the procedures along with full color drawings and operative pictures to enhance understanding. Each chapter fully describes the preoperative setting, the needed materials and the required technical skills that make specific congenital heart defects amenable to minimally invasive surgical treatment. This is the perfect go-to reference for pediatric and congenital cardiac surgeons, and is also a must-have guide for residents in cardiac surgery who are looking to review the technical aspects and outcomes of utilizing a minimally invasive approach for cardiac surgery.

This book represents the first European effort to provide a collection of test descriptions used in evaluation of the compatibility of biomaterials in contact with tissues and blood. The urge to compile this book arose from the fact that it is the properties of the material which ultimatively seem to determine the functional outcome of a medical device, almost regardless of how ingenious the construction of the very device is. The longer the exposure is, the more important these basic properties become. Unfortunately only a small part of the interactive phenomena is fully elucidated and understood. This challenge reflects itself in an effort to cover numerous aspects of testing, beginning with fundamental analysis of the material, continuing with the mechanical properties, the resistance to degradation and the analysis of surface and chemical properties including adsorption patterns of proteins ending with test on cell cultures, ex vivo and in vivo. A number of the tests which are generally accepted as being important are already described as official requirements (primarily Pharmacopeas). These official requirements are not included in order to limit the size of the book. It is the aim of this book to present the tests like a recipe in a uniform way to ease the reader in finding his/her way through the material and to present it as a kind of "cook-book" in an order to provide an easy access to copy the procedures. This has unfortunately not been possible in all circumstances.

The topic of heart failure although extensively researched and reported, has several gray areas. This is especially seen in determining strategies for combating advanced heart failure. The global burden of ischemic heart disease is increasing at an alarming rate to almost pandemic proportions. Even in the presence of state-of the art technology for prompt and successful coronary reperfusion, the population progressing to ischemic cardiomyopathy is substantial. The treatment strategies for ischemic cardiomyopathy do not always ensure optimal clinical results, the reasons for which are varied. The proper patient selection is vital as is the tailoring of suitable therapy. The approach is thus multi-pronged, of which surgical ventricular restoration (SVR) has a definite role. Despite various randomized studies like the STICH-hypothesis 2, where there was a huge selection bias, with patients subjected to an erroneous technique of SVR, with inadequate ventricular remodelling assessment. The present need is to understand the unique anatomy of the left ventricle, its function and perturbations with the onset of heart failure, in order to plan therapeutic strategies to restore near normal anatomy and function. A study of the hemodynamics in ischemic cardiomyopathy is essential, as it differs in certain aspects from other causes of heart failure like idiopathic dilated cardiomyopathy and valvular heart diseases. Since information on these aspects are scattered in various scholarly articles, a concise source in the form of a book would be appropriate and useful for both cardiologists and cardiac surgeons. This project represents a concise review of normal and abnormal cardiac anatomy and physiology, the evolution of SVR to EVLPP with validation of near normal ventricular restoration, plus act as a reference guide for cardiac surgeons with interest in SVR.

As societies have aged and aortic diseases have become more prevalent, advances in diagnostic imaging and surgical techniques have brought significantly improved results for patients. In cardiovascular surgery, important questions remain to be addressed, however. "Strategy for Cardio-aortic and Aortic Surgery" was the theme of the 7th Keio University International Symposium for Life Sciences and Medicine. Meeting in Tokyo, researchers and specialists in cardiac surgery from around the world discussed crucial issues in their field. Papers from the symposium, collected in this volume, cover a broad range of topics, including recent advances in diagnostic imaging, brain protection during aortic surgery, spinal protection during thoracoabdominal aneurysm repair, treatment of type A acute aortic dissection, and stent-grafts and less-invasive aortic surgery. This unique book provides valuable information especially for aortic, cardiovascular, and thoracic surgeons.

A TIMES BEST BOOK OF 2019 An intimate and compelling exploration into the unique psyche of the heart surgeon, by one of the profession's most eminent figures. Although Professor Stephen Westaby was born with the necessary coordination and manual dexterity, it was a head trauma sustained during university that gifted him the qualities of an exceptional heart surgeon: qualities that are frequently associated with psychopathy. His thirty-five-year career has been characterised by fearlessness and ruthless ambition; leaving empathy at the hospital door as thousands of patients put their lives in his hands. For heart surgeons, the inevitable cost of failure is death and in The Knife's Edge, Westaby reflects on the unique mindset of those who are drawn to this exhilarating and often tragic profession. We discover the pioneers who grasped opportunities and took chances to drive innovation and save lives. Often difficult, uninhibited and fearless, theirs is a field constantly threatened by the risk of public failure. Like those before him, Westaby refuses to draw the line in his search of a lifetime solution to problems of the heart. His determination is unerring - a steadfastness underpinned by his unusual mind. But as we glimpse into the future of cardiac surgery, for all its remarkable scientific advancement, one question remains: within the confines of socialised medical healthcare systems, how can heart surgeons - individuals often hardwired with avoidance of self-doubt, a penchant for glory and a flagrant disregard for authority - truly flourish?

Since the publication of the first edition of Cardiac Pacing for the Clinician, the use of implantable cardiac devices has expanded rapidly. Certain classes of devices such as implantable loop recorders and cardiac resynchronization pacing systems were not commonly used when the first edition was published, and recent studies have shown that implantable cardioverter defibrillators are beneficial in large, previously unrecognized patient populations at risk for sudden death. In order to meet this demand, cardiologists without special training in electrophysiology or pacing are implanting an increasing number of cardiac devices. It is in this rapidly evolving setting that Cardiac Pacing for the Clinician, Second Edition is being undertaken.

The main focus of this volume will be to provide a practical discussion of the a oenuts and boltsa of implantable cardiac devices. The target audience will be cardiologists in practice and in training as well as nurses, technologists and industry. In addition, it will benefit physicians preparing for certification.

Additions to the new edition will include: Chapters discussing new cardiac devices; Implantation of Left Ventricular Leads for Cardiac Resynchronization Pacing Systems; Identification of Candidates for Cardiac Resynchronization Therapy; Follow-Up Issues in Cardiac Resynchronization Therapy; Implantable Loop Recorders.

Updates to the existing chapters will include: New Trial Information & Follow-Up of the Newest Generation of Defibrillators; Use of Defibrillators in Patients at Increased Risk for Sudden Cardiac Death due to Long QT Syndrome, Brugada Syndrome and Congenital Heart Disease; Updates to Lead Extraction a" NewTechniques and Tools; Cardiac Pacing chapter will shift focus to Cardiac Devices.

This new edition of Cardiac Pacing for the Clinician, Second Edition will become a valuable resource to the general cardiologist and cardiology fellow by providing practical information for managing patients with complex cardiac devices.
