New or worsening neurologic deficit is an emergency: activate local stroke alert/emergency response immediately and document last known well time. Etiology workup should not delay acute care.

Key takeaways

  • Define cryptogenic/ESUS conceptually
  • List common evaluation components (high-level)
  • Explain why prolonged rhythm monitoring matters
  • Describe PFO closure consideration themes (no thresholds)

Definitions (concept)

  • Cryptogenic
  • ESUS concept

Workup framework

  • Vascular imaging
  • Echo/structural evaluation
  • Rhythm monitoring
  • Labs as appropriate

Prevention strategy categories

  • Risk factor control
  • Antithrombotics per etiology
  • PFO closure consideration in selected patients

Exam pearls

  • Don’t assume ‘unknown’ means ‘no cause’
  • Document what’s ruled out
