Cardiac tuberculosis

Dr Ian Bickle and Dr Aditya Shetty et al.

Cardiac tuberculosis refers to the rare infection of the cardiac musculature with Mycobacterium tuberculosis.

Generally associated with and occurring as a complication of mediastinal and pulmonary tuberculosis.

Pericardial and myocardial involvement is known. Endocardial spread may occur from myocardium. Modes of spread to the myocardium are via  lymphatics from mediastinal nodes, directly from the pericardium, or via a haematogenous route.
