Key result
An 84-year-old female developed a rare case of infective endocarditis caused by Streptococcus gordonii less than two months after transcatheter aortic valve replacement.
Why the study?
IE presentation following TAVR is often atypical and conventional diagnostic methods have low sensitivity, warranting high clinical suspicion.
Case Report (n=1)
This case highlights the need for high clinical suspicion of infective endocarditis in post-TAVR patients presenting with atypical symptoms like heart failure without fever, even involving rare pathogens like Streptococcus gordonii.
Supports vigilance for atypical post-TAVR endocarditis; leaves open the epidemiology of rare pathogens like Streptococcus gordonii.
Infective endocarditis (IE) is an infection of the heart endothelium as well as the heart valve with high mortality rate. The most common cause of infective endocarditis is Staphylococcus aureus. However, IE may be caused by various microorganism depending on the patient risk factor. One of the most important risk factors is the prosthetic heart valve. Patients after transcatheter aortic valve replacement (TAVR) are at risk of IE. The most common organisms to cause IE in TAVR patients are Enterococcus, Staphylococcus aureus, and coagulase-negative staphylococci. The presentation of IE in patients after TAVR is atypical and the conventional ways to diagnose IE have low sensitivity. Therefore the clinician should have high clinical suspicion for it. Herein, we discuss a rare case of infective endocarditis caused by Streptococcus gordonii in a patient who recently underwent TAVR.

Rhabneh et al. (2025) conducted a case report in Infective endocarditis (n=1). Streptococcus gordonii infection was evaluated. An 84-year-old female developed a rare case of infective endocarditis caused by Streptococcus gordonii less than two months after transcatheter aortic valve replacement.
