A rare case of septic pulmonary embolism in co-existence with infective endocarditis and COVID-19.

Infective endocarditis (IE) symptoms including fever, fatigue, dyspnea and myalgia are similar in COVID-19 findings. Therefore, the diagnosis of IE may be missed in patients with COVID-19. Co-existence with IE in COVID-19 is rarely reported. However, to our knowledge, only one case of septic pulmonary embolism in COVID-19 and IE was reported. Here, we describe a case of septic embolism due to tricuspid endocarditis caused by intravenous drug use in patients with COVID-19. In this fatal case, the use of prophylactic anticoagulants due to COVID-19 probably caused the tendency to hemorrhagic cerebrovascular complications. Our report emphasizes the complexity of anticoagulant prophylaxis in patients with COVID-19 which may cause hypercoagulopathy in co-existence with IE.
