The bacilli can reach the heart via lymphatics from mediastinal nodes, hematogenous spread, or by direct invasion from the pericardium. Although the propensity of TB to cause pericarditis and myocarditis is well documented, here we present an extremely rare manifestation of cardiac TB: direct vascular invasion of the main pulmonary artery that was first detected by transthoracic echocardiography (TTE).
