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. The likelihood of a<unk><unk>  diagnosis is less than 10 in 100,000 hospital admissions considering only 9% of acute<unk>  patients develop pericardial constriction. This disease is more prevalent in males with a male-to-female ratio of 3:1.<unk><unk>  has been documented in people 8-70 years of age, with a median of 61 years of age.
