Concurrent right-sided and left-sided endocarditis (bilateral endocarditis) has been reported in 9%-13% of intravenous drug users with endocarditis., , Chiari network or Eustachian valve as the primary focus of right-sided endocarditis, in the absence of tricuspid valve involvement, is rare., We present a case of bilateral infective endocarditis due to Staphylococcus aureus in an intravenous drug user with pulmonary and systemic embolization, where the primary right-sided cardiac involvement was a very large vegetation on the Chiari network rather than on the tricuspid valve.
