Bordetella hinzii Endocarditis, A Clinical Case Not Previously Described

Abstract

Objective: To review infections by Bordetella hinzii. Materials and methods: A 79-year-old male patient, with a chronic aortic valve biological prosthesis, presented to hospital because of fever. First examinations were normal. However, 72 hours later B. hinzii was isolated in blood cultures, and so meropenem was prescribed. Nevertheless, fever and B. hinzii bacteraemia were still present 7 days later. Results: The transoesophageal echocardiogram revealed an enlarged image suggesting a periprosthetic abscess, confirmed with a PET-CT scan. The patient was sent for cardiac surgery, and biopsy samples confirmed the presence of B. hinzii. Conclusion: There are very few cases of B. hinzii infection in humans. Ours is the first described case of B. hinzii endocarditis.
