title: Poor outcome in radiation-induced constrictive pericarditis.
abstract: OBJECTIVE
  To compare the outcome of patients with radiation-induced constrictive pericarditis versus patients with constriction due to another etiology.
  
  
  METHODS
  Twenty patients with constrictive pericarditis seen during 1975-1986 at a single medical center. Six had radiation-induced constrictive pericarditis (Group A). The etiology was idiopathic in ten subjects and secondary to carcinomatous encasement, chronic renal failure, purulent infection and tuberculosis in one patient each (Group B, N = 14). Mean age was 53.4 +/- 15.5 years.
  
  
  RESULTS
  Extensive pericardiectomy was performed in 3/6 Group A and 13/14 Group B patients. All Group A patients died, 4 weeks--11 years post-diagnosis (median = 10 months). Two Group A patients died suddenly, one died post-operatively of respiratory failure, another of pneumonia and two of recurrent carcinoma. Thirteen Group B patients are alive (median follow-up = 72 months). The only death in this group was due to metastatic cancer.
  
  
  CONCLUSIONS
  The poor outcome with radiation-induced constriction is probably multi-factorial. Poor surgical outcome is to be expected in patients with evidence of recurrent tumor, high-dose irradiation, pulmonary fibrosis or associated radiation-induced myocardial, valvular or coronary damage.
