Twenty patients with tuberculous pericarditis who were referred to the Blacksea Technical University Medical School Cardiology Department from January 1979 to January 1992 were followed for 12-18 months by repeated echocardiography, before and after antituberculous therapy. Initial echocardiograms revealed moderate pericardial effusion in 7 patients (35%), and large effusion in 13 (65%). Thickened pericardium was noted in 2. After medical treatment, at the follow-up period, echocardiography revealed small effusion in only 2, the remaining had no effusion. Despite adequate antituberculous therapy, 6 patients developed pericardial thickening, 3 required pericardiectomy for constriction.
