Abstract
Morphological investigations of myocardial biopsy material obtained by percutaneous biopsy from a male patient with suspected cardiomyopathy demonstrated intense fuchsinophilia in the method of Nielsen-Selye, with small differences in the structure of muscle fibers stained routinely and viewed under light microscope. In ultrastructural examinations extensive disintegration (myolysis) of contractile elements was found, with opposite oblique or transverse position of the damaged myofibrils. Morphological changes suggested rather congestive cardiomyopathy which agreed with clinical observations. The usefulness of combined morphological methods for conditions of evaluation of the myocardium was confirmed.
