[72-year-old biker with transient hemisyndrome]

Area of Science:

• Neurology
• Cardiology
• Vascular Medicine

Background:

• Transient ischemic attacks (TIAs) are critical warning signs of stroke.
• Identifying the source of emboli is crucial for preventing recurrent events.
• Atrial fibrillation is a common cause of cardioembolic stroke.

Observation:

• A 72-year-old male biker presented with motor aphasia, facial paresis, and arm weakness.
• Initial diagnosis was TIA, requiring further investigation to determine the etiology.
• Physical examination and diagnostic workup were performed.

Findings:

• Cardiogenic embolization originating from the common carotid artery was identified.
• Newly discovered paroxysmal atrial fibrillation was confirmed as the source of the embolus.
• The patient was otherwise healthy with no significant prior medical history.

Implications:

• Prompt diagnosis and management of paroxysmal atrial fibrillation are essential in TIA patients.
• Understanding the embolic source guides targeted anticoagulation therapy.
• This case highlights the importance of comprehensive cardiac evaluation in TIA workup.
