**4.2 Pericardiectomy for constrictive pericarditis**

Pericardiectomy is the only definitive treatment for established constriction, and most studies suggest that resection should be as complete as technically feasible [49, 54–57]. A retrospective review by Nozohoor et al. showed that radical pericardiectomy was associated with improved functional status and 10-year survival rates of 94% compared to 55% with subtotal pericardiectomy [55]. Bozbuga et al. also showed that performing early radical resection in combination with appropriate chemotherapeutic agents translated into the best outcomes in patients with tuberculous disease [56].
