Transesophageal echocardiography revealed a unique "teddy bear" sign in a patient with aortic valve endocarditis. This unusual finding, representing a perivalvular abscess, highlights echocardiography's diagnostic importance.

Area of Science:

  • Cardiology
  • Medical Imaging

Background:

  • Native aortic valve endocarditis is a serious infection requiring accurate diagnosis.
  • Transesophageal echocardiography (TEE) is a key imaging modality for assessing cardiac structures and pathology.

Observation:

  • A rare "teddy bear" appearance was observed during TEE in a patient with aortic valve endocarditis.
  • This sign was composed of a perivalvular abscess (right ear), superior vena cava (left ear), and dilated aortic root (face).

Findings:

  • The "teddy bear" sign is a novel echocardiographic finding associated with native aortic valve endocarditis.
  • The specific anatomical structures identified represent critical signs of infective endocarditis complications.

Implications:

  • This finding underscores the value of TEE in diagnosing complex endocarditis cases.
  • Early recognition of such signs can guide timely treatment and improve patient outcomes.
