Until recently, the cellular basis for sudden death, the BrugadaSyndrome, has largely remained an unknown to modernarrhythmologists and cardiologists, particularly in the absence ofany structural heart disease. Detailed observations of age-groups,especially the young, families and populations where sudden deathfrequently occurs, and improved understanding of its contributoryfactors and mechanisms are, however, showing the way forward. This addition to the Clinical Approaches to Tachyarrhythmias(CATA) Series, written by the investigators who discovered andprobed the Brugada Syndrome, discusses the history, etiology,pathology and clinical manifestations of sudden death. Fromdiagnosis, prognosis, to therapeutic approaches using the latest incathater ablation techniques, electrophysiological surgery, andgenetic appraisal, the work is a testimony to the author'sinvestigation. Using clinical cases in Thailand and Laos, theyfurther unravel the syndrome's molecular mechanisms, studyingrelated syndromes, such as the long-QT syndrome, infant death, andarryhthmogenic right ventricular cardiomyopathy. By being informed of the electrophysiological abnormalities thatcontribute to familial and genetic diseases, physicians,cardiologists and all those who care for patients with cardiacarrhythmias will be better able to identify and treat patients inwhom the Brugada Syndrome may strike next.

The aim of Molecular Cardiology: Methods and Protocols is to document state-of-the-art molecular and genetic techniques in the area of cardiology. These modern approaches enable researchers to readily study heart diseases at the molecular level and will promote the development of new therapeutic str- egies. Methods for genetic dissection, signal transduction, and microarray analysis are excellent tools for the study of the molecular mechanisms of cardiovascular diseases. Protocols for transgenesis take advantage of recent advances in many areas of molecular and cell biology. Transgenic models of heart diseases (cardiac hypertrophy, cardiac dysfunction, and so on. ) are powerful tools for the study of heart disease pathogenesis. Methods for gene transfer to heart tissue using viral and nonviral vectors form the basis of gene therapy for heart diseases. Heart-specific promoters containing a hypox- inducible cardioprotective gene switch are key for protection of the heart from ischemia. Gene and stem cell therapies open novel and exciting avenues for the prevention and treatment of heart diseases. Molecular Cardiology: Methods and Protocols consists of 26 chapters de- ing with various aspects of molecular cardiology, including gene transfer and gene therapy for cardiovascular disease, stem cell therapy for cardiovascular disease, gene analysis in the injured and hypertrophied heart, and transgenesis in cardiovascular research. This book provides step-by-step methods for the successful completion of experimental procedures, and would be useful for both experienced and new investigators in the field of molecular cardiology.

This book delineates the state of the art of the diagnosis and treatment of J wave syndromes, as well as where future research needs to be directed. It covers basic science, translational and clinical aspects of these syndromes. The authors are leading experts in their respective fields, who have contributed prominently to the literature concerning these topics. J wave syndromes are one of the hottest topics in cardiology today. Cardiac arrhythmias associated with Brugada syndrome (BrS) or an early repolarization (ER) pattern in the inferior or infero-lateral ECG leads are thought to be mechanistically linked to accentuation of transient outward current (Ito)-mediated J waves. Although BrS and ER syndrome (ERS) differ with respect to magnitude and lead location of abnormal J waves, they are thought to represent a continuous spectrum of phenotypic expression termed J wave syndromes. ERS is divided into three subtypes with the most severe, Type 3, displaying an ER pattern globally in the inferior, lateral and right precordial leads. BrS has been linked to mutations in 19 different genes, whereas ERS has been associated with mutations in 7 different genes. There is a great deal of confusion as to how to properly diagnose and treat the J wave syndromes as well as confusion about the underlying mechanisms. The demonstration of successful epicardial ablation of BrS has provided new therapeutic options for the management of this syndrome for which treatment alternatives are currently very limited, particularly in the case of electrical storms caused by otherwise uncontrollable recurrent VT/VF. An early repolarization pattern is observed in 2-5% of the US population. While it is clear that the vast majority of individuals exhibiting an ER pattern are not at risk for sudden cardiac death, the challenge moving forward is to identify those individuals who truly are at risk and to design safe and effective treatments.

This is a detailed clinical compilation on sudden cardiac death causes. From the various geographical regions of the world comes different clinical perspectives toward the SCD problem that shed light on the predictors and estimated prevalence in genetic inheritance worldwide. For many centuries, the mysterious deaths of prominent professional sportsmen have preoccupied the attention of the media and medical professionals. In some cases, it was possible to obtain the medical histories of the victims, data on the presence of some specific diseases, and conditions or potential symptoms preceding the fatal episode. Various rare inherited syndromes that are associated with congenital heart disease are focused on in this study, and the interrelationship between ventricular premature beats, sustained/non-sustained ventricular tachycardias and ventricular fibrillations are discussed. Cardio-oncology is an emerging field where more and more patients face consequences from radiotherapy and chemotherapy because these individuals become more prone to SCD. Among the most notable developments, three-dimensional echocardiography and myocardial strain imaging are worth noting and might inexpensively improve the current risk stratification process. Recently, a strain that reflects the change of length and thickness of myocardial fibres has been incorporated into the routine clinical practice. The risk of sudden cardiac death is not the same in patients with Chagas disease, and newly predicted factors are to blame. The prevalence of SCD, hypertrophic cardiomyopathy and the accurate risk are extremely challenging, so much so that they recently became a source of argument between European and American experts. This is a must-have book for those interested in a clinical approach to the SCD phenomenon.

Clinical cardiologists are encountering an important challenge in the caring of families with inherited cardiac diseases. The majority of the inherited cardiac diseases causing sudden death express themselves at variable ages in the form of altered muscle function (i.e hypertrophic or dilated cardiomyopathy) or in the form of arrhythmias (i.e. Brugada syndrome, long QT syndrome). However, it is not uncommon that the first sign of the disease may actually be sudden cardiac death, even before the identification of clear clinical abnormalities. In this last decade, with more than 50 new disease-associated genes identified, the possibility of genetic testing has opened a new opportunity to disease diagnosis and prevention. Clinical and genetic research is continuously on-going not only to identify those at risk, but to better define their level or risk still with limited success.

Clinical management and signs are the focus of this practical cardiogenetic reference for those who are involved in the care for cardiac patients with a genetic disease. With detailed discussion of the basic science of cardiogenetics in order to assist in the clinical understanding of the topic. The genetic causes of various cardiovascular diseases are explained in a concise clinical way that reinforces the current management doctrine in a practical manner. The authors will cover the principles of molecular genetics in general but also specific to cardiac diseases. They will discuss the etiology, pathogenesis, pathophysiology, clinical presentation, clinical diagnosis, molecular diagnosis and treatment of each cardiogenetic disease separately. Therapy advice, ICD indications, indications for and manner of further family investigation will all be covered, while each chapter will also contain take-home messages to reinforce the key points. The chapters reviewing the different diseases will each contain a table describing the genes involved in each. Each chapter will also contain specific illustrations, cumulatively giving a complete, practical review of each cardiogenetic disease separately. Special emphasis will be given to advice on how to diagnose and manage cardiogenetic diseases in clinical practice, which genes should be investigated and why, and the pros and cons of genetic testing. Guidelines for investigation in families with sudden cardiac death at young age will also be included. This book will be written for the general cardiologist and the clinical geneticist who is involved in cardiac patients and will provide answers to question such as: Which genes are involved and which mutations? What is the effect of the mutation at cellular level? Which genes should be tested and why? What is the value of a molecular diagnosis? Does it influence therapy? When should the first degree relatives be tested and in which way?
