Key result
Off-pump complete pericardiectomy treats pediatric constrictive pericarditis from idiopathic ossification.
Why the study?
Chronic constrictive pericarditis has various known causes, but idiopathic pericardial ossification as a cause in pediatric patients is not well characterized.
Idiopathic ossification may underlie pediatric constrictive pericarditis; extends the differential but remains hypothesis-generating from one case.
BACKGROUND: Chronic constrictive pericarditis (CCP) is usually caused by the fibroinflammatory reaction of the visceral and parietal pericardium that encase the heart. The cause of CCP is various including tuberculosis, trauma, prior surgery, radiation, and malignancy. MATERIAL AND METHODS: We examined the pericardiectomy specimen of a case of CCP in a 17-year-old boy. RESULTS: The histopathology of the pericardium revealed pericardial ossification bony remodeling and hematopoiesis within the intertrabecular marrow spaces. No granulomatous or neoplastic etiology was identified. CONCLUSION: Idiopathic pericardial ossification can cause CCP in pediatric patients.

Biswal et al. (2020) conducted a review in Pediatric pericarditis requiring pericardiectomy. Pericardiectomy was evaluated. Idiopathic pericardial ossification can cause chronic constrictive pericarditis in pediatric patients, which is typically managed with an off-pump complete pericardiectomy via a median sternotomy.
