SARS-CoV-2 virions were localized within both normal and altered cardiomyocytes of COVID-19 patients. (a,c,e) Electron micrograph showing cardiomyocytes containing viral particles, compatible with crown-shaped SARS-CoV-2. The viral particle diameter (a) is about 116 nm. (b,d,f) High magnifications of red squared areas of panels a, c, and e, respectively. In all panels, asterisks indicate normal mitochondrial and sarcomere structures, while cytoplasmic and sarcomere alterations are indicated with hashes.
