Inflammatory Affections. =Carditis.= Inflammation of the muscular substance of the heart is by no means a common disease, and when present, is probably always associated either with endocarditis, or more frequently pericarditis. We may recognize this condition after death, by the light yellow color of the heart; with a relaxed, flabby, and in some instances a softened condition of the walls. Upon cutting into the muscular walls, there will be found exuding a semi-purulent fluid and often small cavities, varying in size from a pin’s head to a small pea, will be found filled with pus. This condition may involve the whole heart, or may be confined to one or more portions. Inflammation of the muscular substance of the heart, may, undoubtedly, be one of the primary causes leading to aneurism or even to rupture. The symptoms of this disease are not readily recognized during life, being always combined with inflammation of the peri- or endocardium. =Pericarditis.= Affections of the pericardium have been noticed in the previous section.
