Ill-defined descriptions and complications of heart disease

Myocarditis unspecified
- inflammation of the muscular walls of the heart.

Myocardial degeneration
- condition in which there is a deviation from or interruption of the normal structure or function of the myocardium, the middle and thickest layer of the heart wall, composed of heart muscle.
- A disease of the heart muscle or myocardium proper. Cardiomyopathies may be classified as either primary or secondary, on the basis of etiology, or on the pathophysiology of the lesion: hypertrophic, dilated, or restrictive.

Representative examples of neoplastic cardiovascular disorders are endocardial myxoma and angiosarcoma. -- 2003
