Abstract
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.
