Pericardial tuberculosis, a form of extrapulmonary TB, can manifest as tuberculous pericarditis. When this presents as pericardial effusion, a specific clinical approach is required that accounts for both the underlying infection and the haemodynamic consequences of fluid accumulation around the heart.
Tuberculous pericarditis presents clinically in three recognised forms: pericardial effusion, constrictive pericarditis, and a combination of effusion and constriction. This protocol addresses the pericardial effusion presentation specifically.
Management is built around a multi-drug antituberculosis regimen. Where the effusion produces haemodynamic compromise, procedural drainage of the pericardial space is also indicated. The complete regimen — including specific agents, sequencing, and duration — is set out in the full protocol.

Tuberculous pericarditis presents clinically in 3 forms, namely, pericardial effusion, constrictive pericarditis, and a combination of effusion and constriction.
Treatment consists of the standard 4-drug antituberculosis regimen for 6 months.
A regimen consisting of rifampicin, isoniazid, pyrazinamide, and ethambutol for at least 2 months, followed by isoniazid and rifampicin (total of 6 months of therapy) has been shown to be highly effective in treating patients with extrapulmonary TB.
Therapeutic pericardiocentesis is indicated in the presence of cardiac tamponade.
