Case Presentation:
A 16-year-old male with past medical history of pericarditis that developed after surgically repaired ASD presented for recurrent episodes of chest pain. He described his chest pain as 7/10, pleuritic, sharp, mid-sternal, and worse when supine. Pain was non-radiating without any associated shortness of breath, fever or chills. Physical examination and vital signs were within normal limits. Cardiovascular exam showed regular rate, normal rhythm, S1, S2 sounds, and no pericardial rub. His chest pain began a few months after surgery, and at that time he was diagnosed with acute idiopathic pericarditis. After diagnosis, he frequently experienced flares limiting his daily activities. During these episodes, he was intermittently treated with a combination of non-steroidal anti-inflammatory drugs (NSAIDs), colchicine, and prednisone.
