A 34-year-old previously healthy Japanese woman was diagnosed with COVID-19 and treated with remdesivir and dexamethasone. She was discharge but returned the next day due to acute myocardial infarction. Conservative treatment was selected because of an embolic occlusion in the distal portion. Contrast-enhanced computed tomography and brain magnetic resonance imaging revealed a right renal infarction and multiple cerebral embolisms, respectively; she had a fever of 38.9°C that night. Blood culture was positive for methicillin-susceptible Staphylococcus aureus. Transthoracic echocardiography revealed an 11-mm vegetation on the posterior mitral valve leaflet. Native mitral valve infective endocarditis causing multiple embolizations was diagnosed. She underwent surgical mitral valve replacement.
