Abstract

Right-sided infective endocarditis occurs in approximately 5~10% of all infective endocarditis cases. It is associated with intravenous drug abuse, indwelling intravenous catheters, congenital heart disease, alcoholism, and skin infection; however, infective endocarditis involving the tricuspid valve caused by Haemophilus species is uncommon. Here we report a case of tricuspid valve endocarditis caused by H. parainfluenzae in a 29-year-old male patient with insulin- dependent diabetes mellitus who injected himself repeatedly with insulin under unsanitary conditions.
