Abstract
BACKGROUND: Species of the genus Acinetobacter are Gram-negative and highly drug-resistant bacilli that normally reside on the skin, oropharynx, and perineum. Several previous studies have reported prosthetic valve endocarditis due to A. baumannii infection. CASE PRESENTATION: Here we present a case of late endocarditis of a bioprosthetic tricuspid valve due to A. baumannii complex in a patient who had surgical replacement with a bioprosthetic tricuspid valve six years previously. CONCLUSIONS: We completed tricuspid valve replacement using a 29 mm St. June mechanical prosthetic valve for the patient. Postoperatively, she received intravenous cefoperazone sodium and sulbactam sodium for 2 months and had good recovery.
