The objective of this Atlas is to contribute to the knowledge of morphological findings of the main cardiovascular diseases among the various specialists who deal with people affected of heart diseases: cardiologists and cardiovascular surgeons, clinical and forensic pathologists, coroners, sports medicine doctors. The interest in cardiovascular pathology, neglected for years in many countries, is increasing worldwide and we are witnessing the revitalization of a discipline, which, in collaboration with clinicians, is making great contributions to the fight against heart diseases and sudden-unexpected deaths. This atlas of cardiovascular diseases is the result of close collaboration between Spanish specialists in cardiology and in cardiovascular pathology and describes the clinical and pathologic features (gross and histopathologial) of major cardiovascular diseases in adults, especially those acquired, but also treat relevant congenital anomalies. This book contains 635 images, 78 tables and graphics distributed in 12 chapters across the spectrum of diseases that can be found in each of the structures of the cardiovascular system (aorta, pulmonary vessels, coronaries, valves, myocardium, pericardium and conduction system). The coordinated work of forensic pathologists from different cities in Spain and cardiologists (primarily from the Hospital Universitario Puerta de Hierro de Madrid) has assembled in all chapters their two worlds (forensic pathology and cardiology) to achieve a practical work with the aim to serve as a practical tool for multiple specialists.
