SANTOS, José M. et al. Clinical finding and follow up of chronic constrictive pericarditis. Medicina (B. Aires) [online]. 2010, vol.70, n.4, pp.316-320. ISSN 0025-7680.

The aim of this study was to describe the etiology, clinical findings, diagnostic methods, treatment, outcome and long-term prognosis of 35 patients with chronic constrictive pericarditis (CCP) that were prospectively analyzed according to a pericardial disease protocol performed in our Institution. Etiology of CCP was idiopathic in 24 patients (68%), and specific in 11 (32%). The majority (34 patients, 97%) underwent pericardiectomy. Perioperative mortality was 12% (4/33) no deaths were registered among patients with idiopathic CCP. Median follow-up was 5.6 years (percentile 25-75: 2.4-7.4 years). The cumulative actuarial survival probability was 97% at 1 year (confidence interval [CI] 80% to 99%); 83% at 5 years, (95% CI 65% to 93%); 78% at 7 years, (95% CI 60% to 90%), and 69% at 10 years (95% CI 50% to 84%). In conclusion, nowadays CCP is generally an idiopathic disease with late diagnosis. The clinical course of the disease produces severe symptoms of congestive heart failure. In a 10 years follow-up 2/3 of patients are alive and improved their quality of life. Idiopathic form of pericarditis did not show mortality during early postoperative period.
