Recurrent pericarditis is one of the main complications of acute
pericarditis that affects approximately 20–50% of all patients with
acute pericarditis . It usually occurs after the first episode of acute pericarditis with a symptom-free interval of 4–6 weeks. The specific etiology includes infectious, neoplastic, autoimmune, or autoinflammatory causes, but in 70% of the cases, the etiology remains unknown.
