Isolated Native Tricuspid Valve Endocarditis in an HIV Patient due to Streptococcus Pneumoniae: A Rare Clinical Phenomenon

Streptococcus pneumonia is an important cause of septicemia. Other sites of infection include meningitis, septic arthritis, and endocarditis. Pneumococcal endocarditis is rare and has a poor prognosis. We report a case of a 47-year-old female patient with HIV who developed isolated native tricuspid valve endocarditis secondary to streptococcus pneumonia, which is considered to be a very rare presentation in our patient due to the absence of common risk factors such as intravenous drug use, heart disease, or right heart catheterization.
