Cryopreserved allograft tissues are now standard materials for the reconstructive cardiac surgeon. Since publication of the first edition ("Cardiac Reconstructions with Allograft Valves") in 1989, the field has progressed dramatically with increased clinical use of cardiovascular allograft tissues, with the development of new surgical techniques, and with advances in the understanding of the fundamentals of valve transplantation biology and cryopreservation. As a result, over two-thirds of the present volume represents new material. Fifty-six authors bring their expertise to thirteen comprehensive, lavishly illustrated sections which discuss the principles of the use of homograft valves, major clinical series of homograft valves for both left and right ventricular outflow tracts, cryopreserved allograft tissue for cardiac reconstruction, cell biology of heart valve leaflets, cryobiology of heart valve preservation, morphological, biochemical, and explant pathology studies of allograft heart valves, allograft valve banking, as well as detailed explanation of surgical techniques for valve and root methods for left and right ventricular outflow tract reconstructions, the Ross operation and variants, and complex reconstructions. A final section presents potential future directions for the field. Over 400 illustrations, created expressly for this book, depict the surgical techniques from the perspective of the surgeon standing at the operating table. All surgeons performing pediatric and/or adult valve replacements and reconstructive cardiac surgeries will benefit from the described methods. Cardiothoracic residents and cardiologists will also find the text useful. It will provide the surgeon with an enhanced understanding of the biological and material properties of allografts and increased familiarity with the range of surgical techniques applicable for the use of these valves, particularly in the successful management of challenging cardiac reconstructions.>
Transmediastinal gunshot injuries present the risk of immediately life threatening injuries. Stable patients have been evaluated by a combination of esophageal swallow and endoscopy, aortography and bronchoscopy. There is an increasing trend favoring CT scan. Unstable patients require immediate exploration, being prepared to enter both hemi-thoraces. Selected References: * Bergsland J, Karamanoukian HL, Soltoski PR, Salerno TA.

Heart transplantation remains one of the major scientific achievements of twentieth century medicine. During the past four decades, it has evolved from an unproven experimental surgical technique to the most effective form of therapy for refractory end-stage heart disease. It has captured the public's imagination and expanded our understanding of fundamental immunologic mechanisms that are responsible for cellular and humorally-mediated immunity. Despite its successes, many clinical and scientific problems remain. One or more bouts of acute cellular or humoral (vascular) rejection will occur in over 75% of transplant recipients despite current immunosuppressive strategies. Further, rejection directly results in approximately 20% of post-transplant deaths and is believed to play a major role in the development of late allograft dysfunction and coronary vasculopathy. This book by international experts in the fields of transplantation medicine, immunobiology and cardiac imaging provides the reader with an up-to-date, consise summary of the latest developments in the diagnosis and treatment of acute cardiac rejection. It is axiomatic that a more complete understanding of the pathogenic processes involved in rejection will ultimately lead to its prevention. This volume will be useful to transplant cardiologists, cardiovascular surgeons, cardiac pathologists and transplant scientists who seek to prolong the lifespan and improve the quality of life of their transplant recipients.
ICD therapy has become the standard form of treatment for ventricular tachyarrhythmias. With clinical data showing its efficacy in both secondary and primary prevention of premature sudden death, its use is likely to increase dramatically in the next decade. Technological advancement has been instrumental in simplifying ICD implantation. However, technical additions to the device have also made its scope of functions more complex. In addition to providing rapid and effective therapy for ventricular tachycardia and fibrillation, the ICD is now capable of providing a full spectrum dual-chamber pacing as well as therapies for atrial fibrillation. Soon, it will also be able to provide treatment for congestive heart failure using multi-site ventricular pacing and provide continuous hemodynamic monitoring. This book serves as an introductory text to those who are relatively new to this technology. In its manual form, it outlines the pertinent components of ICD functions and the basic differences among the various models. It provides practical points in ICD implantation, and in its programming and trouble-shooting.
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.
Cardiac surgery is performed on hundreds of thousands of patients a year, and can have an important beneficial impact on the outcomes of patients with coronary and valvular heart diseases. Despite the favorable recovery of most patients, some will have their post-operative period interrupted by the development of atrial fibrillation, with a host of potential complications including stroke. High risk subgroups may develop atrial fibrillation in more than half of cases, and often despite aggressive prophylactic measures. Treatment of atrial fibrillation and its aftermath can also add days to the hospital stay of the cardiac surgical patient. In an era of aggressive cost cutting and optimization of utilization of health care resources, the financial impact of this arrhythmic complication may be enormous. Experimental studies have led to a greater understanding of the mechanism of atrial fibrillation and potential precipitating factors in the cardiac surgical patient. Prophylactic efforts with beta-blockers, antiarrhythmic drugs and atrial pacing are being used, or are being investigated in clinical trials. New methods of achieving prompt cardioversion with minimal disruption of patient care, and prevention of the thromboembolic complications of atrial fibrillation, are also important therapeutic initiatives. This text is designed to aid health care professionals in the treatment of their patients in the recovery period after cardiac surgery, and to instigate additional research efforts to limit the occurrence of, and the complications following, this tenacious postoperative arrhythmia.
The new WHO Classification of Lung and Pleural Tumours updates the previous proposal from 1981 and incorporates many new concepts that have developed since that time. A number of newly described lesions are included as well as current concepts in papillomas, adenomas, neuroendocrine tumours, adenocarcinomas, mesothelial tumours, and carcinomas with pleomorphic, sarcomatoid and sarcomatous features. The result is a comprehensive classification with detailed definitions and explantory notes illustrated by 150 high quality color photomicrographs that will promote uniformity in recording and reporting data nationally and internationally. The WHO panel consisted of 24 members from 14 countries giving a broad international input into this work.

A comprehensive review by renowned authorities of the many exciting
developments occurring across the rapidly emerging field of
"minimally invasive" or "minimal access" cardiac surgery. The
book's distinguished panel of contributors presents the
interventional cardiologists perspective, spells out the key
factors for success in beating-heart coronary bypass grafting
through limited incisions, and surveys the various methods of
harvesting the internal thoracic artery. Other topics treated
include immobilization of the surgical field, minimal access valve
and congenital surgery, alternative methods of anastomosis, and
port-access coronary bypass grafting. Minimally Invasive Cardiac
Surgery summarizes all the latest findings on the powerful new
techniques, as well as the results, of minimally invasive coronary
surgery, including valvular heart disease, congenital heart
disease, and coronary revascularization.
Significant changes have taken place in the realm of cardiac, thoracic, and vascular surgery during the last five to ten years. Many new operative procedures have been developed which remain relatively unknown to cardiothoracic surgeons. This practical manual covers a wide variety of these new processes, several of which are interventions offered to cardiologists practicing in the field of electrophysiology who are unaware that these interventions exist and can help them in situations they cannot solve. It includes general practical techniques; cardiac, thoracic, and vascular surgery procedures; and advances in cardiology and electrophysiology. Throughout the book, illustrations accompany the technical descriptions and show in step-by-step detail how to perform the operations and various procedures using proper equipment. Cardiothoracic Surgical Procedures and Techniques: A Practical Manual is an essential resource for physicians and related professionals, residents, fellows, physician assistants (PA), and graduate students in cardiology, cardiac surgery, thoracic surgery, and vascular surgery.
Cardiac performance is regulated not only by cardiac muscle properties but also by several other factors, including those associated with the neurohumoral system and the mechanical characteristics of the peripheral circulation. New information con cerning these regulatory factors has furthered our understanding of the pathophysi ology of cardiac dysfunction. However, controversy remains, along with a need to integrate these multidisciplinary findings. It was with this in mind, together with my continuing interest in the response of the normal and diseased heart to variations in loading conditions, that the satellite symposium entitled "Interactions Between Car diac Function and Vascular Dynamics" was organized and dedicated to my mentor, Dr. T. Takishima. The symposium was held in Fukushima, Japan, in 1992 following the Tenth Inter national Conference of the Cardiovascular Systems Dynamics Society in Kobe, Japan, which was organized by the then president of the society, Dr. Masatsugu Hori. The Fukushima symposium and the Kobe conference were stimulating and informative. To commemorate these events, Dr. Hori, Dr. Janicki, and I decided to publish this book. It covers topics that were presented then as well as pertinent new material. As a result, the book includes not only updated reviews but also up-to-date findings that were not considered at the two scientific sessions. The high level attained in this book is due to the outstanding contributions from internationally renowned scientists. This final product of their efforts should prove to be a valuable source of information to the reader.
HE IMPLANTABLE CARDIOVERTER DEFIBRILLATOR, or T"lCD," is arguably the most technologically challenging type of therapy that physicians utilize today. At the same time, engineers who design ICDs are being called upon by clinicians to extend even further the technological envelope in quest of building the "ideal" device. To the extent, however, that physicians who utilize ICDs are not sufficiently comfortable with or familiar with the engineering principles that guide ICD function, the full clinical potential of even an ideal device will not be realized. In comple mentary fashion, engineers require as full an appreciation as possi ble of the real world "boundary conditions" and clinical impact of various ICD features, if the latter are truly to be perfected. This book is intended to serve as an educational tool to foster mutual understanding and communication among physicians, engineers, and other professionals involved in ICD therapy, with the ultimate purpose of enhancing patient care. The highly varied backgrounds of such a diverse audience posed obvious challenges in the preparation of this volume. Given the overwhelmingly greater involvement of clinicians in the day-to day management and follow-up of ICD recipients, we gave high priority to the presentation of oftentimes complex yet relevant engi neering concepts in a manner that could be understandable to most clinicians."
The topics in this book represent the presentations given at the Seventh Annual Meeting entitled "Cardiac Surgery: Current Issues," held at the Frenchman's Reef Beach Resort, St. Thomas, U.S. Virgin Islands, November 9-12, 1994. This symposium was sponsored by the American College of Chest Physicians in conjunction with the Division of Cardiothoracic Surgery of Cooper HospitallUniversity Medical Center, the University of Medicine and Dentistry of New Jersey, Robert Wood Johnson Medical School, Camden, New Jersey. Chapter authors were charged with the task of writing brief overviews of major issues related to the field of cardiac surgery. The book is specifically tailored to the needs of cardiothoracic surgeons, cardiovascular perfusionists, allied health professionals, and nurs ing personnel involved in all phases of caring for the cardiac surgical patient. Although intended as a reference source with emphasis on updated approaches applied in cardiac surgery, it is hoped that the discussion of these topics will compliment other texts and manuscripts. Obviously, a book of this length cannot cover the whole multidisciplinary and complex field of cardiac surgery. However, co-editors are certain that the annual appearance of this text will highlight comprehensive, new, and interesting approaches to the field of cardiac surgery. The co-editors are greatly thankful to the contributors for their efforts in providing comprehensive chapters. Without their expertise, this work may not have been possible. We would also like to thank Ms. Eileen Birmingham and the staff at Plenum Publishing Corporation for their tremendous help in completing this work.
Since the first pacemaker implantation in October 1958 by Senning and Elmqvist in Sweden, cardiac pacing for bradycardia has become a well-established therapy. The impressive growth of clinical experience and the rapid development of pacemaker devices have greatly contributed to this situation. The electrical therapy appears to be so easy that insertion of the lead and its connection to the pacemaker generator requires little effort, skill or insight. However, after implantation a patient's condition seldom remains stable, which requires a flexible pacing program to cover all new cardiac events, and broad insight from clinician and technical colleagues. The Pacemaker Clinic of the 90's teaches anatomical and electrophysiological aspects of pacing, supports the prevention of complications, and points to new developments in the field. Apart from classical indications for cardiac pacing, the book discusses the validity of the latest indications, supporting the cardiologist and the associated professional in selecting the appropriate pacing mode and pacemaker follow-up in individual patients. The Pacemaker Clinic of the 90's will be a helpful companion for years to come.
The motivation for this book was the recognition by two of us (RL and TL) that, despite our training as cardiologists, we had a limited understand ing of many aspects of the surgical management of our patients. Conversa tions with other cardiologists at our own institution and at other medical centers around the country convinced us that many of our colleagues shared our uncertainty about the details of surgical procedures and the factors that determine decisions in the perioperative period. As surgical techniques continue to evolve, this knowledge gap can become only more severe. We therefore compiled information about cardiac surgery that might be useful for cardiologists and other nonsurgeons. We asked cardiologists what questions they would like to ask their surgical colleagues and provided these questions to the authors of the chapters. Thus, the goal of these chapters is to help nonsurgeons answer their own questions about common cardiac procedures, and to help prepare these physicians to address the questions raised by their patients. In addition, we hope that insight into these issues will improve communication between surgeons and their col leagues-and, ultimately, lead to better patient care.

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.
This heavily revised second edition of this book provides a comprehensive overview of both common and rarely performed thoracic surgical techniques. Techniques covered include thymectomy, left and right lower lobectomy, rib resection for empyema, median sternotomy and lung biopsies. Emphasis is focused on the practical steps necessary to successfully and reliably perform the techniques covered, while acknowledgement is also given to individual variations in how these techniques are performed. Thoracic Surgical Techniques provides a detailed clinical illustrative guide for successfully performing a range of procedures reliably. Its large number of detailed illustrations and concise technical descriptions provides an invaluable resource for all practising and trainee thoracic surgeons.
Attempts to reconstruct various parts of the heart started even before the beginning of open cardiac surgery. By the late 1950s and early 1960 s several closed and open procedures had already been described. In that era, several surgeons in Europe and the Americas were particularly prompted to develop various techniques of valve re construction because of the lack of acceptable valve prostheses and conduits which have become available subsequently. At that time, several congenital lesions still defied definitive correction, and clinical attempts at left ventricular wall replacement had not yet got under way. A renaissance in different cardiac reconstructive procedures started at the beginning of the 1980s. As the problems relating to valve prostheses became more generally appreciated and the importance of chamber volumes and geometry (atrial or ventricular) was accorded due importance in the long-term follow-up, there was a resurgence of surgical attempts at reconstruction in congenital and acquired cardiac lesions so as to approximate the natural state. At the same time several characteristics of this reconstructive "discipline" became apparent. First, cardiac reconstructive surgery has remained a surgical "art" with a gradually increasing number of interested cardiac surgeons."
Fibrin plays a central role in wound healing. It has a hemostatic effect by forming a temporary wound closure and assists in neovascularization and fibroblast prolifera- tion. It therefore makes the repair of injured or severed parts of the human body by simple glueing possible, a notion that men have dreamed of since ancient times. The first modern attempts in this direction, using clotting substances derived from human blood to achieve hemostasis, were reported by Bergel (in 1909), Grey (in 1915), and Harvey (in 1916), who used fibrin powder or fibrin patches to control bleeding from parenchymatous organs. Two decades later Young and Medawar (1940) and Cronkite (1944) used blood plasma or fibrin solutions, adding thrombin to seal nerve anastomoses and to fix skin grafts in humans. Due to the poor adhesive strength of the fibrinogen the results were unsatisfactory. In 1972 a new era in fibrin sealing was initiated by Matras. By using highly concentrated fibrinogen in combination with factor XIII (fibrin-stabilizing factor) and by delaying fibrinolysis with a fibrinolysis inhibitor (aprotinin), a method was developed which after satisfactory results in animals, soon began to be applied in humans.
Die Endoskopie vermochte bisher Gewebsformationen zu dehnen, zu durchtrennen, abzutragen und zu zerstoren. Gewebedefekte auszufullen, miteinander zu vereinigen und zu heilen, war bislang endoskopisch nicht moglich. Die Einfuhrung von Fibrinklebern eroffnete neue Anwendungsbereiche. Der Kleber kann, in seine Komponenten getrennt, uber doppellumige Sonden uber beliebig weite Strecken an den vorgesehenen Einsatzort unter Sicht des Endoskopes transportiert werden. Die Klebung von Fisteln, Rupturen oder Leckagen an Bronchusstumpfen, im Lungenparenchym oder an gastrointestinalen Anastomosen kann heute komplizierte Heilungsverlaufe und riskante operative Re-Interventionen ersetzen. Die spezielle Technik der endoskopischen Fistelklebung wird in diesem Buch erstmals zusammenfassend und interdisziplinar erortert. Daneben werden neue Moglichkeiten zur Stillung gastrointestinaler Blutungen mit Fibrin durch intramurale Injektion oder oberflachlichem Spray besprochen. Grundlegende Untersuchungen zeigen, dass im Vergleich zu anderen Substanzen, die Fibrinapplikation in das Gewebe zu deutlich geringerer Traumatisation und zu geringeren entzundlichen Reaktionen bei gleichem Hamostaseeffekt fuhrt. Ziel des vorliegenden Buches ist, verstreute Einzelbeobachtung zu sammeln, zu ordnen und zu vergleichen, um dem interessierten Leser die neue Technologie der Verklebung von Defekten und der Hamostase mit biologischen Substanzen zu vermitteln.
Effective treatment of acute myocardial infarction remains one of the major issues in cardiology and internal medicine. The present monograph summarizes the relevant experimental data and the results of major clinical trials in the treatment of myocardial infarction. There are contributions of fundamental anatomical and physiological concepts of vascular occlusion and myocardial damage due to ischemia as well as discussions of therapeutic strategies involving thrombolytic agents, adjuvant drug therapy for limitation of myocardial damage, improvement in myocardial tolerance to ischemia and prevention of coronary reocclusion. In this regard, there is an extensive discussion of the role of coronary angioplasty and bypass surgery in the setting of acute myocardial infarction.
Brain injury is one of the most unacceptable complications sustained during heart surgery. This book presents the current results and thinking of a number of leading clinical investigators in this area. Nearly all have been active in serious studies designed to define various aspects of brain physiology, patho physiology, or protection during cardiac operations performed with cardio pulmonary bypass. We were particularly interested in obtaining contributions from younger investigators. Brain injury is a problem which has long troubled those involved with perioperative care of the cardiac surgical patient. The first chapter by Dr. Torkel Aberg presents a summary of his extensive investigations into this problem. It is intended both to present the perspective of a surgeon interested in this problem, and to serve as an introduction to the overall issue of avoiding brain injury during heart surgery. The next three chapters discuss the problem of perfusion pressure, outcome, and brain blood flow. Dr. Sarnquist's contribution stems from his extensive experience with low flow bypass as practiced at Stanford University and the results of the studies he performed in collaboration with Dr. Fish. Drs. Govier and Reves discuss in some detail the general effects of anesthetic agents upon brain metabolic needs as well as their important data demonstrating preserva tion of brain blood flow autoregulation during cardiopulmonary bypass (CPB) as practiced at the University of Alabama. Finally Dr.
Over the past ?fty years, advanced techniques and strategies have arisen in the ?eld of myocardial protection. Meticulous trials, focusing on pulmonary protection during heart surgery requiring cardiopulmonary bypass (CPB), have been missing. This te- book is intended to serve as a useful tool to spread information on strategies for lung protection during heart surgery with CPB. Emphasis on pulmonary protection will be turned to lung perfusion as an adjunct for minimizing the deleterious effects of pulmonary ischemia-reperfusion injury in heart surgery. Many renowned authors have contributed by presenting their expe- ence on lung perfusion in basic research and clinical trials. Furthermore, they have enlightened the quality of this textbook with new ideas, concepts, and future perspectives. The scope of this textbook is of interest to different professionals, such as card- vascular surgeons, pulmonary surgeons, transplantation physicians, cardiothoracic anesthesiologists, intensive care physicians, cardiothoracic fellows, radiologists, basic sciences physicians, cardiologists, pulmonary medicine physicians, perfusi- ists, nurses, students, and researchers. This textbook has 7 sections, aimed at addressing general and speci?c aspects of pulmonary protection during heart surgery with CPB. The ?rst section on general concepts provides information about anatomic, physiologic, histologic, molecular, and radiologic considerations regarding the lungs. The second section focuses on ischemia-reperfusion injury and is composed of several interesting chapters, addressing the basic science aspects of pulmonary p- tection, as well as experimental and clinical experiences from different heart surgery centers worldwide.
