The paper describes 4 autopsy cases of myocarditis in elderly patients with confirmed coronavirus infection. It gives the data of a morphological study of heart specimens and a detailed characterization of a myocardial infiltrate. ⋯ The fact that lymphocytic viral myocarditis can develop in COVID-19 was morphologically and immunohistochemically confirmed. The features of myocarditis in COVID-19 are the development of the former in the presence of coronaritis and the possibility of its concurrence with lymphocytic endo- and pericarditis.
