Right-sided IE is referred to as infective endocarditis that affects the tricuspid or pulmonic valve. In the 1980s, a coagulase-negative staphylococci (CoNS) member has been identified as a causative agent of infective endocarditis. Coagulase-negative staphylococci (CoNS) form a vast majority of gram-positive cocci shared by their mutual lack of the virulence factor coagulase. More than 50 distinct CoNS species have so far been identified. Six species in total are thought to have a higher therapeutic importance, including S. S. epidermidis, S. saprophyticus, S. haemolyticus, S. capitis as well as S. lugdunensis. Several species, such as S. Serious clinical illness is known to be caused by lugdunensis. In prosthetic valves, CoNS causes 20– 45% of endocarditis cases. Most strains of contamination are methicillin-resistant and typically occur after surgery. CoNS are not frequently found in native valve endocarditis, 1– 3% are the typical percentages given. Pulmonary artery embolization (PAE) is a serious consequence of infected endocarditis (IE). We report a case of 37 years old with right-sided valve endocarditis caused by coagulase-negative endocarditis complicated by septic embolism.Keywords: Infective endocarditis, coagulase-negative staphylococci, septic embolism, right-sided infective endocarditis, tricuspid valve vegetation
