Calcific Aortic Valve Disease

Due to population aging, calcific aortic valve disease (CAVD) has become the most common heart valve disease in Western countries. No therapies exist to slow this disease progression, and surgical valve replacement is the only effective treatment. Calcific Aortic Valve Disease covers the contemporary understanding of basic valve biology and the mechanisms of CAVD, provides novel insights into the genetics, proteomics, and metabolomics of CAVD, depicts new strategies in heart valve tissue engineering and regenerative medicine, and explores current treatment approaches. As we are on the verge of understanding the mechanisms of CAVD, we hope that this book will enable readers to comprehend our current knowledge and focus on the possibility of preventing disease progression in the future.

This book describes the field of osteocardiology, an exciting and new sub-discipline within cardiovascular science, which will become the cornerstone for defining the timing and treatment of cardiovascular calcification in the future. With the advent of large cohort databases and experimental mechanistic studies, research has elucidated evidence confirming that traditional cardiovascular risk factors are responsible for the development of atherosclerotic calcification and identified the critical elements of atherosclerosis, including foam cell formation, vascular smooth muscle cell proliferation and extracellular matrix synthesis, which over time forms bone in the heart. Osteocardiology: Cardiac Bone Formation is a practical overview of bone formation in the heart and is destined to become the cornerstone for education of medical students, residents, fellows, graduate students, physician scientists and scientists, for future research and ongoing development in medical therapies to slow or halt the progression of bone formation in the heart.

Calcific aortic valve stenosis is the most frequent valvular heart disease in Western countries, affecting up to 13% of individuals over 75 years. The disease is associated with considerable morbidity and mortality. It is characterized by fibro-calcification of aortic valve cusps and concomitant left ventricular remodelling due to chronic pressure overload, which can evolve into overt heart failure. It progresses very slowly until the onset of symptoms, the indication for aortic valve replacement. Today, about 300,000 aortic valve replacements are performed annually worldwide, either via surgery or transcatheter implantation. This is the only treatment shown to improve survival. There is no pharmacological treatment to prevent or slow disease progression. Major risk factors include older age, congenital anomalies of the aortic valve (bicuspid valve), male gender, hypertension, dyslipidaemia, smoking, and diabetes. However, how these factors contribute to the disease in unclear. Due to the disease itself, patients are at increased risk of both thrombosis and bleeding, which, in addition to advanced age and comorbidities, makes antithrombotic management of these patients difficult. Regarding valve prostheses, the ideal prosthesis either mechanical or biological still does not exist. Clinically available prostheses can lead to major complications, thrombosis or infection, which necessitate reoperation or cause death in 50-60% of patients within 10 years post-implantation. Hence, there are major unmet medical needs in CAVS and more basic and translational research is definitely required. Our Research Topic depicts major challenges and research paths that could be followed to address these major health needs.

Much has evolved in the field of aortic valve disease because of the increase in knowledge in the last decade, especially in the area of its management. This book "Aortic Valve" is comprised of 18 chapters covering basic science, general consideration of aortic valve disease, infective endocarditis, aortic sclerosis and aortic stenosis, bioprosthetic valve, transcatheter aortic valve implantation and a special section on congenital anomalies of the aortic valve. We hope this book will be particularly useful to cardiologists and cardiovascular surgeons and trainees. We also believe that this book will be a valuable resource for radiologists, pathologists, cardiovascular anesthesiologists, and other healthcare professionals who have a special interest in treating patients with aortic valve disease. We are certain that information in this book will help to provide virtually most new areas of aortic valve disease that will be employed in the current era.

Calcific aortic valve disease (CAVD) is one of the most common forms of valve disease. It has become the most widespread cardiac valve disease in the economically advanced nations. Population ageing is one of the major reasons for this increasing rate. Th

The book covers the basic science and clinical aspects of cardiovascular calcification and bone mineralization. Cardiovascular calcification is the leading predictor of cardiovascular morbidity and mortality, with a predictive value more significant than blood lipid levels. The presence of calcific mineral in cardiovascular tissues alters biomechanical performance, increasing workload on the heart and potentiating atherosclerotic plaque rupture and subsequent heart attack and stroke. This book examines the role of calcification in cardiovascular disease covering topics such as calcification in the atherosclerotic plaques and aortic valves arteries and valves, aortic valve replacement, peripheral artery disease, imaging of early calcification and target discovery. In addition, various forms of ectopic calcification as well as mechanisms of bone mineralization are discussed. Cardiovascular Calcification and Bone Mineralization is an essential resource for clinicians, researchers, and other medical professionals in cardiology, pathology, and biomedical engineering.

This volume focuses on the etiology and morphogenesis of congenital heart diseases. It reviews in detail the early development and differentiation of the heart, and later morphologic events of the cardiovascular system, covering a wide range of topics such as gene functions, growth factors, transcription factors and cellular interactions that are implicated in cardiac morphogenesis and congenital heart disease. This book also presents recent advances in stem cell and cell sheet tissue engineering technologies which have the potential to provide novel in vitro disease models and to generate regenerative paradigms for cardiac repair and regeneration. This is the ideal resource for physician scientists and investigators looking for updates on recent investigations on the origins of congenital heart disease and potential future therapies.
