Thrombus in the left ventricle of a child with systemic emboli: An unusualpresentation of hereditary protein C deficiency

We present a case of left ventricular thrombus in a child with a normal fun ctioning left ventricle. The diagnosis was made by 2-dimensional echocardio graphy after 2 episodes of systemic emboli. Hereditary protein C deficiency diagnosed in the patient provides the proba ble pathogenesis of the thrombus formation. Systemic emboli necessitates cardiac examination, and in cases of unusual t hrombi, hereditary or acquired thrombophilic risk factors should be conside red.
