COVID-19 Myopericarditis With Pericardial Effusion Complicated With Cardiac Tamponade and Rhabdomyolysis.

COVID-19 infection is a complex multi-organ disease, including the cardiovascular system, which may present with myocarditis. A 42-year-old female presented to our ED with generalized weakness, myalgia, and epigastric pain. Laboratory workup showed a positive SARS-CoV-2 polymerase chain reaction (PCR). An ECG showed sinus tachycardia with low voltage. A bedside echocardiogram showed a pericardial effusion with cardiac tamponade. An emergent pericardiocentesis was performed with immediate hemodynamic improvement. The patient was admitted to the coronary care unit (CCU), and colchicine and ibuprofen were started for pericarditis. Pericardial fluid bacterial and fungal cultures were negative, and serum antinuclear antibodies were also negative. On day 5 of hospitalization, creatine kinase (CK) level was high compared to on presentation. COVID-induced rhabdomyolysis was suspected and was dramatically improved with IV fluids. The patient was discharged on day 7 of admission. Our case shows that COVID-19 can present with an uncommon presentation like cardiac tamponade. Further studies are warranted to better understand the pathogenesis and management of COVID-19 myopericarditis.
