Abstract

Background: The coronavirus disease 2019 (COVID-19) has caused a global pandemic with a significant negative impact on health worldwide. Although it primarily involves the respiratory tract system, cardiovascular complications, particularly thrombotic events are increasingly reported and are associated with adverse outcomes.
Case Summary: We describe a 30-year-old male who presented with exaggerated dyspnea and hypoxia with mild constitutional symptoms along with a positive PCR test for SARS-CoV-2. He was a known case of bronchiectasis and large bullae in the left lung. Transthoracic echocardiography showed a large right ventricle (RV) mass entrapped within RV papillary muscles and apex. Cardiac MRI was suggestive of RV thrombosis. Regarding diffuse underlying lung disease and improving respiratory symptoms with COVID-19 negative PCR test, we decided to prescribe anticoagulation with heparin infusion and then oral anticoagulant with Rivaroxaban 20 mg daily and follow up after 30 days. Unfortunately, the patient died after 2 weeks in his hometown.
Conclusion: Thrombotic complications are frequently encountered in COVID-19 patients. We report a fatal case of large intracardiac thrombus associated with SARS-CoV-2 infection managed with anticoagulant therapy with a catastrophic outcome.
