Introduction
Salmonella species are important bacterial pathogens
that cause foodborne diseases in developed and developing
countries. It is estimated to cause more than 1.2
million illnesses each year in the United States with more
than 23,000 hospitalizations and 450 deaths.

Salmonella
isolates often cause human infections ranging from mild
gastroenteritis to severe invasive infections, especially in
infants, the elderly, and immunocompromised hosts.
Any anatomical site may be seeded hematogenously by
Salmonella; however, the involvement of the cardiovascular
system is a rare but serious disease.
Many
studies have investigated a complication of Salmonella
bacteremia, infected aortic aneurysm, because it is
associated with a high mortality rate if not diagnosed and
treated early.

However, Salmonella endocarditis is
uncommon, and its clinical characteristics and prognosis
have not been fully defined. In this paper, we report a
case of Salmonella enteritidis bacteremia and aortic
valve endocarditis complicated with perivalvular abscess.
In addition, to delineate the temporal evolution of Salmonella
endocarditis, we summarized the clinical manifestations
in 14 similar cases published in the past
decade, and compared them with reports in two earlier
reviews.
