Cardiac tuberculosis: TB of the endocardium

Tuberculosis involving the endocardium is extremely rare. The diagnosis is usually made during autopsy. Often there is involvement of other parts of the heart as well as other regions of the body. The infection is a result of direct extension from the myocardium or hematogenous spread. Two cases of disseminated tuberculosis with endocardial involvement are reported. In Case 1 miliary tuberculosis was diagnosed during life but the patient succumbed to extensive disease on the third hospital day. The patient in Case 2 presented with congestive cardiac failure and the possibility of tuberculosis was not suspected during life.
