Atrial Myxomas:

  • Rare primary heart tumor
  • Most involve the left side of the heart
  • Symptoms may include fatigue, fever, rash, chest pain, syncope, and/or focal neuro deficits
    • Symptomatic emboli occur in 20-45% of pts with atrial myxomas
    • >50% of emboli go to the brain
    • Hemiplegia, aphasia, retinal artery occlusion, embolic “rash” in a child should all raise concern for cardiac source in pediatric pt.
      • Embolus from the heart is the most common cause of retinal artery occlusion in pts <40yrs.
  • Emboli are most often myxoma tissue and not blood clot (so thrombolytics aren’t of much value)
