Widespread systemic embolization with isolated tricuspid valve endocarditis.

Concurrent systemic and pulmonary septic emboli from isolated right-sided infective endocarditis are rare. One mechanism described is that of intrapulmonary shunting. We describe a case of widespread pulmonary and systemic septic embolization with sequelae in an intravenous drug user with concomitant chronic hepatitis C infection and discuss possible mechanisms involved in the pathogenesis.
