[Virological and morphological results in patients with congestive cardiomyopathy (author's transl)].

In 30 patients with congestive cardiomyopathy, right ventricular biopsies were performed. The biopsy material was investigated by virological and morphological methods. In all cases it was impossible to isolate viruses from the right ventricular myocardium, corresponding to the lack of infiltrative changes as shown by morphology. Results point against a direct causative role of viruses in the genesis of congestive cardiomyopathy.
