Prosthetic aortic valve endocarditis can cause serious complications. This case highlights how valvular dehiscence after aortic valve replacement can mimic an abscess, requiring surgical intervention.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Infectious Diseases

Background:

  • Prosthetic aortic valve endocarditis is a severe complication associated with high mortality.
  • Aortic root abscess is a known, grave complication of infective endocarditis.
  • Early diagnosis and management are crucial for favorable outcomes.

Observation:

  • A patient presented with echocardiographic findings suggestive of aortic root abscess six weeks post-aortic valve replacement.
  • Severe aortic regurgitation was noted.
  • The appearance was attributed to valvular dehiscence, not infective endocarditis.

Findings:

  • Valvular dehiscence of the prosthetic aortic valve led to a perivalvular abscess-like appearance.
  • Infective endocarditis was definitively excluded as the cause.

  • The patient underwent successful redo aortic valve surgery.

    • Implications:

    • This case underscores the importance of considering mechanical complications like valvular dehiscence in the differential diagnosis of perivalvular collections post-valve replacement.
    • Distinguishing between infective and non-infective causes is critical for appropriate management.
    • Successful surgical correction of valvular dehiscence can lead to recovery even in complex cases.
