Discussion
Based on our review of 1976 to 2014 in the English literature,
only 87 cases of Salmonella endocarditis were reported,
and among 16 large case series, Salmonella
endocarditis accounted for less than 0.01% and up to 2.9%
of bacterial endocarditis cases, which reflects the rarity of
cardiac involvement by Salmonella species. Of note among
the patients with available information, the mean age of
disease presentation was in the sixth decade of life. The
major affected valves were the mitral valves. Mural endocarditis
and perivalvular abscess were noted in nearly onefourth
and one-tenth, respectively, of the cases. The
overall prognosis of 87 reported cases of Salmonella
endocarditis was grave with a mortality rate of 42.5%.
