Carotid-retinal embolism with coexistent mitral valve prolapse

Area of Science:

• Cardiology
• Neurology
• Ophthalmology

Background:

• Central retinal artery embolus can cause sudden vision loss.
• Hypertension is a significant risk factor for cardiovascular events.

Observation:

• A 63-year-old woman with hypertension and mitral valve prolapse experienced sudden left eye blindness.
• Carotid arteriography revealed an ulcerated plaque in the left internal carotid artery.

Findings:

• The ulcerated plaque had a large, friable platelet thrombus, identified during endarterectomy.
• Mitral valve prolapse is common in the general population and may be incidental.

Implications:

• Mitral valve prolapse should not be the sole focus when evaluating embolic stroke.
• Comprehensive stroke evaluation is crucial, considering various potential embolic sources.
