Embolic stroke of undetermined source (ESUS): potential causes

Evidence-based neurology checklist on embolic stroke of undetermined source (esus): potential causes: Conventional cardiac causes Arterial thromboembolism Paroxysmal atrial fibrillation (PAF) Patent foramen ovale (PFO) Congenital left ventricular diverticulum Cardiac structural abnormalities…

Conventional cardiac causes

  • Arterial thromboembolism
  • Paroxysmal atrial fibrillation (PAF)
  • Patent foramen ovale (PFO)
  • Congenital left ventricular diverticulum
  • Cardiac structural abnormalities
  • Atrial fibrosis
  • Occult cardiomyopathy: consider cardiac MRI

Left atrial dysfunction

Atrial cardiopathy
