Epidemiology

Constriction can occur after almost any pericardial process. Historically, the most common etiology was tuberculosis, but in the modern age, this cause now accounts for <2% of cases. In a study of 95 patients undergoing pericardiectomy at Stanford, no cause could be found in 42% of patients. 31% occurred after radiotherapy, particularly following high dose mantle radiation for Hodgkin’s disease. Pericardial constriction occurred a mean of 85 months after radiotherapy, but occurred as early as 1 month and as late as 244 months.

It also occurred post-operatively in 11% of cases. Connective tissue disorders accounted for 4%, neoplasm 3%, uremia 2% and sarcoidosis for 1% of cases.
