A patient with Bjork-Shiley mechanical mitral valve was noted to have
Salmonella prosthetic valve endocarditis, which was confirmed by posit
ive blood cultures and vegetation found by transesophageal echocardiog
raphy. Up to now, only 5 cases of Salmonella prosthetic valve endocard
itis have been reported in the literature. Because of the malignant co
urse of this rare infection, the authors suggest that early surgical i
ntervention should be considered in Salmonella prosthetic valve endoca
rditis, especially when the patients have recurrent fever during medic
al treatment.
