Abstract

Background: Right-sided infective endocarditis (IE) is uncommon. Furthermore, Streptococcus agalactiae (S agalactiae) rarely causes IE, with only 2% to 9% of bacteremia cases manifesting as endocarditis.

Case Presentation: A 30-year-old Lebanese woman presented to the emergency department with high-grade fever and chills. Blood tests were obtained, urinalysis showed leukocytes, and treatment for urinary tract infection was initiated. The patient was hospitalized 3 days later and transferred to the ICU. Echocardiography revealed severe right-sided cardiomegaly, flail tricuspid leaflets with ruptured chordae, and a large coaptation defect. She was diagnosed with right-sided IE due to S agalactiae and underwent tricuspid valve replacement. Unfortunately, the patient died from acute decompensated heart failure.

 

Conclusion: This case represents an unusual instance of right-sided IE due to S agalactiae in Lebanon, for which definitive treatment guidance remains limited.
