Causes of mechanical heart valve


Cerebrovascular accident [top]

  • Acute neurological deficit: dysphasia, hemiparesis, hemianopia
  • Deficit persists for greater than 24 hours
  • Risk factor for embolism: atrial fibrillation, ventricular thrombus, carotid artery stenosis, mechanical heart valve

Transient ischaemic attack [top]

  • Acute neurological deficit: dysphasia, hemiparesis, hemianopia
  • Deficit resolves within 24 hours
  • Risk factor for embolism: atrial fibrillation, ventricular thrombus, carotid artery stenosis, mechanical heart valve
