Among the coagulase-negative staphylococci, Staphylococcus lugdunensis is important because it behaves as a pathogen similar to S aureus. She subsequently underwent TAVR given high surgical risk. On hospital day 10, the patient developed ventricular tachycardia with cardiac arrest and was successfully resuscitated after one round of cardiopulmonary resuscitation. Transesophageal echocardiography of infected TAVR. Most (73%) infections were located below the waist, while those above the waist were mainly (5/7) breast abscesses. In 1980, he began .

Staphylococcus lugdunensis belongs to the group of coagulase-negative staphylococci (CoNS). Given persistent bacteremia and strong clinical suspicion for PVE following TAVR, antibiotic therapy was transitioned to vancomycin, gentamycin, and rifampin. However, microbiological elements for identification of Staphylococcus lugdunensis are curious.

Staphylococcus lugdunensis is a recently described coagulase-negative staphylococcus that has been associated with human infections, including nine reported cases of infective endocarditis. NCI CPTC Antibody Characterization Program. S. lugdunensis is coagulase negative due to the lack of production of secreted coagulase, but a membrane-bound form of the enzyme present in some isolates can result in misidentification of the organism as Staphylococcus aureus in the clinical . It appears closest to S. aureus in terms of clinical sig- It should never be dismissed as a contaminant without careful review. No vegetations or abscesses were visualized. Recognized as an emerging opportunistic pathogen, S. lugdunensis is responsible of (28.9%), followed by Enterococcus spp. The presentation with complete heart block and intraoperative findings of widespread tissue involvement and left main coronary obstruction by vegetative material highlight the pathogenicity of Staphylococcus lugdunensis—an uncommon but virulent organism.

Those with aortic valve involvement are at higher risk of developing heart block due to the proximity of the His-Purkinje system to the aortic valve [6]. Staphylococcus lugdunensis has occurred by a different pathway from that of other pathogenic coagulase-negative staphylococcal species. Staphylococcus aureus. Staphylococcus lugdunensis is a member of the coagulase-negative staphylococci with the potential to cause clinically significant infections. First described in 1988 by Freney in Lyon, France, 1 this emerging pathogen is more virulent than other CoNS and can cause infections with high mortality.
