Abstract  Coagulase-negative staphylococci are generally not considered to be very virulent; they are an uncommon cause of native valve endocarditis. Staphylococcus lugdunensis is an important exception and causes more severe infections, clinically mimicking S. aureus. We present a case of direct Gerbode defect associated with S. lugdunensis native valve infective endocarditis (IE) requiring cardiac surgery.
