A patient with bacterial endocarditis experienced altered consciousness and fever. Electroencephalogram (EEG) revealed triphasic waves during illness, which normalized with antibiotic treatment, suggesting a novel association.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Clinical Medicine

Background:

  • Bacterial endocarditis is a serious infection affecting heart valves.
  • Altered consciousness can be a neurological manifestation of systemic infections.
  • Electroencephalography (EEG) is used to assess brain electrical activity.

Observation:

  • A 45-year-old woman presented with probable bacterial endocarditis, characterized by a deteriorating level of consciousness and fever.
  • During the acute phase of her illness, EEG monitoring revealed classical triphasic waves.
  • These EEG abnormalities resolved as the patient's clinical condition improved with antibiotic therapy.

Findings:

  • The study reports a novel association between the presence of triphasic waves on EEG and bacterial endocarditis.

  • Triphasic waves, typically associated with metabolic encephalopathy, were observed in a patient with infectious endocarditis.
  • Resolution of triphasic waves correlated with successful treatment of bacterial endocarditis.

    • Implications:

    • This finding suggests that triphasic waves on EEG may indicate central nervous system involvement in bacterial endocarditis.
    • It highlights the importance of EEG in evaluating neurological complications of infective endocarditis.
    • Further research is warranted to explore the pathophysiology and diagnostic utility of this association.
