Abstract
The infection caused by the novel coronavirus (COVID-19) immersed the globe into a widespread pandemic. The disease leads to acute respiratory disease syndrome , hypercoagulation, and cardio-vascular diseases. In this case report, we presented an 80-year-old man with right atrial clot and acute pulmonary embolism, who was diagnosed with COVID-19. The patient was isolated and transferred to the intensive care unit with a diagnosis of submissive pulmonary thromboembolism and right atrial clot following COVID-19 infection. Antibiotics and anticoagulants were administered, and the patient was referred for mechanical thrombectomy. He did not die and after recovery, was discharged with warfarin administration. Preventing thromboembolic events seems to be the first priority in the management of COVID-19 patients. It is necessary to look for strategies to manage and prevent the early occurrence of thromboembolic events in these patients.
