This case report details the first instance of Prevotella Intermedia infective endocarditis (IE) in a patient with a history of aortic valve replacement. The patient developed an aortic root abscess and heart block, highlighting anaerobic IE features.

Area of Science:

  • Infectious Diseases
  • Cardiology
  • Microbiology

Background:

  • Prevotella species commonly cause head and neck abscesses post-dental procedures.
  • Prevotella intermedia-related infective endocarditis (IE) has not been previously documented.
  • Anaerobic bacteria are an underrecognized cause of IE, particularly in patients with prosthetic valves.

Observation:

  • A 22-year-old male with a prior aortic valve replacement presented with fever and chest pain.
  • Blood cultures identified Prevotella Intermedia as the causative agent.
  • The patient developed a rapidly progressing aortic root abscess, hypotension, and third-degree atrioventricular block.

Findings:

  • This is the first reported case of Prevotella Intermedia infective endocarditis (IE).

  • The patient's presentation included classic signs of severe anaerobic IE: aortic root abscess, hypotension, and atrioventricular block.
  • Successful aortic valve re-do surgery was performed, with an unremarkable postoperative course.

    • Implications:

    • This case expands the spectrum of known pathogens causing infective endocarditis.
    • It underscores the importance of considering anaerobic bacteria in IE, especially in patients with cardiac prosthetic material.
    • Early recognition and appropriate management, including surgical intervention, are crucial for favorable outcomes in complex IE cases.
