Cardiac Reconstructions

by Probal K. Ghosh Felix Unger

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.

Cardiac Tissue Engineering (Synthesis Lectures on Tissue Engineering)

by Smadar Cohen Emil Ruvinov Yulia Sapir

Cardiac tissue engineering aims at repairing damaged heart muscle and producing human cardiac tissues for application in drug toxicity studies. This book offers a comprehensive overview of the cardiac tissue engineering strategies, including presenting and discussing the various concepts in use, research directions and applications. Essential basic information on the major components in cardiac tissue engineering, namely cell sources and biomaterials, is firstly presented to the readers, followed by a detailed description of their implementation in different strategies, broadly divided to cellular and acellular ones. In cellular approaches, the biomaterials are used to increase cell retention after implantation or as scaffolds when bioengineering the cardiac patch, in vitro. In acellular approaches, the biomaterials are used as ECM replacement for damaged cardiac ECM after MI, or, in combination with growth factors, the biomaterials assume an additional function as a depot for prolonged factor activity for the effective recruitment of repairing cells. The book also presents technological innovations aimed to improve the quality of the cardiac patches, such as bioreactor applications, stimulation patterns and prevascularization. This book could be of interest not only from an educational perspective (i.e. for graduate students), but also for researchers and medical professionals, to offer them fresh views on novel and powerful treatment strategies. We hope that the reader will find a broad spectrum of ideas and possibilities described in this book both interesting and convincing.

Cardinalities of Fuzzy Sets (Studies in Fuzziness and Soft Computing #118)

by Maciej Wygralak

Counting is one of the basic elementary mathematical activities. It comes with two complementary aspects: to determine the number of elements of a set - and to create an ordering between the objects of counting just by counting them over. For finite sets of objects these two aspects are realized by the same type of num­ bers: the natural numbers. That these complementary aspects of the counting pro­ cess may need different kinds of numbers becomes apparent if one extends the process of counting to infinite sets. As general tools to determine numbers of elements the cardinals have been created in set theory, and set theorists have in parallel created the ordinals to count over any set of objects. For both types of numbers it is not only counting they are used for, it is also the strongly related process of calculation - especially addition and, derived from it, multiplication and even exponentiation - which is based upon these numbers. For fuzzy sets the idea of counting, in both aspects, looses its naive foundation: because it is to a large extent founded upon of the idea that there is a clear distinc­ tion between those objects which have to be counted - and those ones which have to be neglected for the particular counting process.

Cardio-Respiratory Control in Vertebrates: Comparative and Evolutionary Aspects

by Mogens L. Glass Stephen C. Wood

Hopefully, this book will be taken off of the shelf frequently to be studied carefully over many years. More than 40 researchers were involved in this project, which examines respiration, circulation, and metabolism from ?sh to the land vertebrates, including human beings. A breathable and stable atmosphere ?rst appeared about 500 million years ago. Oxygen levels are not stable in aquatic environments and exclusively water-breathing ?sh must still cope with the ever-changing levels of O 2 and with large temperature changes. This is re?ected in their sophisticated count- current systems, with high O extraction and internal and external O receptors. 2 2 The conquest for the terrestrial environment took place in the late Devonian period (355–359 million years ago), and recent discoveries portray the gradual transitional evolution of land vertebrates. The oxygen-rich and relatively stable atmospheric conditionsimpliedthatoxygen-sensingmechanismswererelativelysimpleandl- gain compared with acid–base regulation. Recently, physiology has expanded into related ?elds such as biochemistry, molecular biology, morphology and anatomy. In the light of the work in these ?elds, the introduction of DNA-based cladograms, which can be used to evaluate the likelihood of land vertebrates and lung?sh as a sister group, could explain why their cardio-respiratory control systems are similar. The diffusing capacity of a duck lung is 40 times higher than that of a toad or lung?sh. Certainly, some animals have evolved to rich high-performance levels.

Cardiomyocytes – Active Players in Cardiac Disease

by Klaus-Dieter Schlüter

This book summarizes our current understanding about the biology and patho-biology of cardiomyocytes and depicts common techniques for the study of these cells. The book is divided into two parts; the first part provides insight into role and function of cardiomyocytes under normal conditions and describes embryogenesis and differentiation, in the second part the role of cardiomyocytes in aging and disease is discussed and cellular responses under stress conditions illustrated. Cardiomyocytes represent the main mass of the heart, and cellular malfunction directly modifies heart function leading to subsequent heart failure. As such, cardiomyocytes are causative involved in the main reasons of heart failure, such as post-infarct remodeling, hypertensive heart disease, idiopathic heart failure, and interactions with other co-morbidities such as diabetes. On the other hand, cardiomyocytes are necessarily target of therapy. Therefore, a precise understanding of cardiomyocytes biology is a pre-requisite for proper disease treatment and evidence based medicine. The book is written for cell biologists, pharmacologists and biomedical researchers specialized in cardiac and vascular biology.

Cardiomyocytes in Health and Disease

by Chandrasekharan C. Kartha

This book is a treatise on cardiomyocytes, the most important cell for the contractile function of the heart. There has been significant progress in our understanding of the function-related structure, developmental processes and their determinants, mechanisms of cell cycle regulation, post-natal growth, energy metabolism, and reversible and irreversible response of cardiomyocytes to diverse forms of physiological stress and injury. There is also more clarity on the alterations in the biological mechanisms in cardiomyocytes that lead to pathological states and the changes in the cells that occur secondary to disease conditions. Thanks to these advances in knowledge, there have been great gains in attempts to identify disease biomarkers and therapeutic targets for better management of patients with heart diseases. Possibilities to induce regeneration or proliferation of cardiomyocytes and thus repair and or regenerate the damaged heart are also on the horizon.

Cardiotoxicity of Non-Cardiovascular Drugs

by Giorgio Minotti

Some drugs which are not aimed at treating heart disease have nevertheless been found to have profound effects on heart muscle. Cardiotoxicity is one of the major forms of toxicity seen in drugs and it accounts for most drug recalls and delays experienced in regulatory approvals.In recent years a number of non-cardiac blockbuster drugs such as terfenadine have been withdrawn from major markets because of cardiotoxicity concerns, while other drugs have either been withdrawn prior to marketing or required labelling changes that significantly restricted their use. In Cardiotoxicity of Non-Cardiovascular Drugs international experts describe the molecular mechanisms and clinical read-outs of cardiac events induced by a broad variety of noncardiovascular drugs. Particular emphasis is paid to the preclinical screening of drug cardiotoxicity. Topics include: metabolic targets of cardiotoxicity regulatory aspects translating molecular mechanisms into clinical trials structure-activity relationships in arrhythmias by antihistamines and psychoactive drugs cardiovascular toxicity of antitumor drugs cardiovascular toxicities of non-steroidal anti-inflammatory drugs cardiovascular toxicities of antiretroviral therapies Cardiotoxicity of Non-Cardiovascular Drugs is an essential guide to this important area of drug development. It will find a place on the bookshelves of researchers, regulators and students in medicinal chemistry, drug development, pharmacology, pharmacy and cardiovascular disease.

Cardiovascular and Cardiac Therapeutic Devices (Studies in Mechanobiology, Tissue Engineering and Biomaterials #15)

by Thomas Franz

This volume focuses on latest research in therapeutic devices for cardiovascular, i.e. vascular and valvular and cardiac diseases. In the area of vascular therapies, aspects covered relate to latest research in small-diameter tissue-regenerative vascular grafts, one of the greatest persisting challenges in cardiovascular therapies, stent grafts and endovascular stents for percutaneous arterial interventions. Contributions on valvular therapies focus on tissue engineered and tissue regenerative prosthetic heart valves and valvular prostheses for trans-apical implantation including the challenges posed on the prosthesis design. The section on cardiac diseases aims at covering therapeutic advances for myocardial infarction and prevention of heart failure and on in vivo biomechanics of implantable cardiac pacemaker devices. A further section complements these three areas by presenting constitutive modelling of soft biological tissues of the cardiovascular system, an area imperative for advanced numerical and computational modelling in the development and optimisation of cardiovascular devices and therapies.
