Pediatric Autoimmune Pancarditis Complicating Congenital Heart Disease, Kerala

Key finding

> What did standard medicine miss or get wrong? The authors explicitly frame autoimmune carditis in children as "uncommon and often overlooked, particularly in regions where rheumatic fever is endemic." In India, where rheumatic heart disease remains a dominant cause of pediatric valvulopathy, the diagnostic default for a child presenting with multivalvular regurgitation and pericardial effusion is rheumatic in origin — not primary autoimmune pancarditis superimposed on a separate, previously silent congenital defect. This case shows both problems occurring simultaneously and required histopathology (fibrinous pericarditis with chronic inflammation) and immunologic workup to disentangle from the regionally "expected" rheumatic pattern.
