This case report details a stroke patient diagnosed with nonbacterial thrombotic endocarditis (NBTE). Early diagnosis and treatment with aspirin and ticlopidine led to a good clinical outcome and vegetation regression.

Area of Science:

  • Cardiology
  • Neurology
  • Pathology

Background:

  • Stroke is a critical neurological event often linked to cardiac embolic sources.
  • Nonbacterial thrombotic endocarditis (NBTE) is a rare condition characterized by sterile vegetations on heart valves, posing an embolic risk.

Observation:

  • A 38-year-old female presented with stroke symptoms.
  • Transesophageal echodoppler cardiogram revealed mitral valve prolapse with an anterior leaflet vegetation, suspected as an embolic source.

Findings:

  • The patient showed no signs of infection, and her clinical condition improved.
  • Valvular vegetation regressed without antibiotic therapy, supporting a diagnosis of NBTE.
  • This case represents the first reported antemortem diagnosis of NBTE with a favorable outcome.

Implications:

  • Early diagnosis of NBTE is crucial for preventing embolic events like stroke.
  • Treatment with antiplatelet agents such as aspirin and ticlopidine may be effective in managing NBTE.
  • This case highlights the importance of considering NBTE in stroke patients with cardiac vegetations.
