Tuberculous pericarditis: long-term outcome in patients who received medical therapy alone

A conservative approach to operative intervention in the treatment of active tuberculous pericarditis was adopted and only 4 of 16 consecutive patients underwent pericardiectomy, all within 2 months of diagnosis. One patient died of constrictive pericarditis despite pericardiectomy, and one died of acute bronchopneumonia after 8 months of otherwise successful medical management. All 14 long-term survivors were reevaluated to exclude chronic constrictive pericarditis and other potential sequelae of tuberculous pericarditis. Reevaluation included physical examination, chest radiograph, electrocardiogram, M-mode and two-dimensional echocardiogram, computed tomography (CT) scan, and in patients less than or equal to 75 years of age, incremental cycle exercise to maximum oxygen consumption. None were found to have chronic constrictive pericarditis or convincing evidence of other recognized complications of tuberculous pericarditis. Our results suggest that when pericardiectomy is not required for the relief of cardiac compression during the acute phase of tuberculous pericarditis and patients are treated with medical therapy alone, an excellent long-term outcome may be anticipated.
