Pediatric COVID-19 and Pericarditis Presenting With Acute Pericardial Tamponade.

We describe a seven-year-old female with acute pericarditis presenting with pericardial tamponade, who screened positive for coronavirus disease 2019 (COVID-19 [SARS-CoV-2]) in the setting of cough, chest pain, and orthopnea. She required emergent pericardiocentesis. Due to continued chest pain and orthopnea, rising inflammatory markers, and worsening pericardial inflammation, she underwent surgical pericardial decortication and pericardiectomy. Her symptoms and pericardial effusion resolved, and she was discharged to home 3 days later on ibuprofen and colchicine with instruction to quarantine at home for 14 days from the date of her positive testing for COVID-19.
