ABSTRACT
A 78-year-old man with COVID-19 infection was admitted. Initial echocardiography indicated left ventricular ejection fraction (LVEF) of 15%, high pulmonary arterial pressure, severe left ventricular dysfunction, mild diastolic dysfunction, mild regurgitation mitral valve, and normal septal thickness. Considering the probable diagnosis of COVID-19-related myocarditis, the patient was early managed with the antivirals, immunomodulatory agents, a high dose of ascorbic acid, melatonin, and immunoglobulin therapy. His clinical condition was improved and his last echocardiography revealed LVEF of 40% and improvement in systolic and diastolic dysfunction. The clinicians should be aware of the potentially lethal cardiac complication of COVID-19, especially in geriatrics.
