Bioprosthetic tricuspid valve endocarditis caused by Acinetobacter baumannii complex, a case report and brief review of the literature.

Chen Q, Cao H, Lu H, Qiu ZH, He JJ - J Cardiothorac Surg (2015)

Bottom Line: Species of the genus Acinetobacter are Gram-negative and highly drug-resistant bacilli that normally reside on the skin, oropharynx, and perineum.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.

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.

Fig2: The damaged bioprosthetic tricuspid valve with vegetations

Mentions: We completed valve replacement in the beating heart under cardiopulmonary bypass, during which we noted vegetations on all 3 leaves and damage to 2 of the leaves (Figs. 1 and 2). We used a dilute iodine solution in normal saline- cefoperazone sodium to irrigate the surface of the tricuspid annulus after removal of the bioprosthetic valve. A 29 mm St. June mechanical prosthetic valve was inserted according to the patient’s choice. Intraoperative cultures of the vegetations were negative. Postoperatively, she received intravenous cefoperazone sodium and sulbactam sodium for 2 months. Before discharge, all post-operative numerous blood cultures showed negative results and the patient reported that cardiac insufficiency-related symptoms were significantly ameliorated. During the follow-up period, there was no fever, no symptoms of infection, and no cardiac insufficiency.Fig. 1
