Pathophysiology of heart failure caused by dysfunction or destruction of cardiac myocytes or their molecular components. In congenital diseases such as Duchenne muscular dystrophy, the molecular structure of individual myocytes is affected. Myocytes and their components can be damaged by inflammation (such as in myocarditis) or by infiltration (such as in amyloidosis). Toxins and pharmacological agents (such as ethanol, cocaine, doxorubicin, and amphetamines) cause intracellular damage and oxidative stress. The most common mechanism of damage is ischemia causing infarction and scar formation. After myocardial infarction, dead myocytes are replaced by scar tissue, deleteriously affecting the function of the myocardium. On echocardiogram, this is manifest
American Association of Tissue Banks The AATB also accommodates accreditation to non-transplant tissue banks and whole body donation programs. To avoid violating the Health Insurance Portability and Accountability Act, AATB must through their legal anatomical authorizations obtain consent which allows AATB representatives access to donor information for accreditation reviews. American Association of Tissue Banks The American Association of Tissue Banks (AATB); a transplant trade organization that is dedicated to ensuring that human tissues intended for transplantation are safe and free of infectious disease, of uniform high quality, and available in quantities sufficient to meet the needs of the national. The AATB provides accreditation for over
