Streptococcus oralis pulmonic valve endocarditis: a case report and review of the literature

J Med Case Rep. 2023 Apr 3;17(1):120. doi: 10.1186/s13256-023-03835-y.

Abstract

Background: Several factors increase the risk of right-sided endocarditis. The tricuspid valve is usually involved in right-sided endocarditis cases. Infective endocarditis of the pulmonic valve is rare, and few cases of pulmonic valve endocarditis were reported previously.

Case presentation: Here we describe a case of a 81-year-old Middle Eastern male patient, admitted to our hospital three times in a period of 2 months for fever and cough. He had Streptococcus oralis bacteremia with vegetation that was on the pulmonic valve. We diagnosed him with pulmonic valve endocarditis, and he was treated successfully with intravenous antibiotics.

Conclusion: It is important to keep high suspicion for isolated pulmonic valve endocarditis in patients with respiratory symptoms. Adequate dental care is important in patients with risk factors for infective endocarditis.
