A rare case of a valvular strand, possibly giant Lambl's excrescences, caused an embolic stroke in a healthy woman. Current evidence is insufficient to establish standard patient management or treatment recommendations for this condition.

Area of Science:

  • Cardiology
  • Neurology
  • Pathology

Background:

  • Embolic stroke is a serious neurological event often linked to cardiac or vascular sources.
  • Valvular strands, including giant Lambl's excrescences, are rare cardiac masses that can embolize.
  • The association between valvular strands and embolic events like stroke requires further investigation.

Observation:

  • A previously healthy 47-year-old woman presented with an acute embolic stroke.
  • Transesophageal echocardiography revealed a filiform structure on the aortic valve, diagnosed as a valvular strand.
  • Differential diagnoses included papillary fibroelastoma and other benign cardiac tumors.

Findings:

  • The valvular strand was presumed to be a giant Lambl's excrescence.
  • This case highlights the potential embolic risk associated with valvular strands.

  • Existing literature on valvular strands and their embolic potential is limited.

    • Implications:

    • This case underscores the importance of considering rare cardiac masses in the etiology of embolic stroke.
    • Further research is needed to elucidate the pathogenesis and establish definitive management strategies for valvular strands.
    • Current evidence does not support standardized treatment protocols for patients with valvular strands causing embolic events.
