Pericardial windows or pericardiocentesis for pericardial effusions

The hospital records of 20 patients admitted to Parkland Memorial Hospital in Dallas with pericardial effusion during the four-year period of 1966 to 1969, and who underwent pericardiocentesis and percutaneous open pericardial windows, were reviewed. The etiologies of the effusions were as follows: purulent pericarditis (5), hypertensive and ischemic heart disease with congestive heart failure (4), and chronic idiopathic effusion (4). Specific etiologic diagnoses were made from the pericardial biopsy in only two cases (10 per cent), while 13 (65 per cent) had at least one serious complication in the postoperative period with eight (40 per cent) developing secondary infection. Twenty-one patients underwent pericardiocenteses without complications and four etiologic diagnoses (20 per cent) were made. Suggestions for indications for these procedures are presented.
