The source of the bacteremia may be an infection in another organ (eg, pneumonia, pyelonephritis) or in a central venous catheter. Most often, these patients are in the intensive care unit. Approximately 45% of cases of NIE/HCIE occur in patients with prosthetic valves. Muted IE due to S aureus infection may resemble IE that results from S viridans infection.
