Key result
A child with repaired tetralogy of Fallot developed right-sided infective endocarditis caused by the emerging cardiotropic pathogen Staphylococcus lugdunensis.
Why the study?
Staphylococcus lugdunensis is an emerging cardiotropic coagulase-negative staphylococcus that presents similarly to Staphylococcus aureus, presenting clinical challenges regarding potential culture contamination.
Case Report (n=1)
Staphylococcus lugdunensis is an emerging cardiotropic pathogen that can cause right-sided infective endocarditis in children with repaired congenital heart disease.
May warrant vigilance for S. lugdunensis in right-sided IE after congenital repair; leaves open questions on prevalence and risk.
Infective endocarditis is often caused by bacterial pathogens and can affect native and prosthetic tissue. Common pathogens in pediatric patients include Staphylococcus aureus, viridans group streptococci, enterococcal species and coagulase-negative staphylococci, though culture-negative cases are not uncommon. Coagulase-negative staphylococci present a conundrum to clinicians due to the potential of culture contamination. While Staphylococcus lugdunensis is a coagulase-negative staphylococcus, it is an emerging cardiotropic pathogen that presents similarly to Staphylococcus aureus. Here we report a case of a child with repaired tetralogy of Fallot found to have right-sided infective endocarditis caused by Staphylococcus lugdunensis.

Becken et al. (2019) conducted a case report in Right-sided infective endocarditis in repaired tetralogy of Fallot (n=1). Staphylococcus lugdunensis infection was evaluated. A child with repaired tetralogy of Fallot developed right-sided infective endocarditis caused by the emerging cardiotropic pathogen Staphylococcus lugdunensis.
