Summary
Calcified bicuspid aortic valve leaflets caused a retinal embolism, leading to vision loss. Despite moderate aortic regurgitation, aortic valve replacement was not advised, but anticoagulant therapy was initiated.
Area of Science:
- Cardiology
- Ophthalmology
- Vascular Medicine
Background:
- A 36-year-old man presented with vision loss in his left eye due to retinal embolism.
- The underlying cause was diagnosed as a calcified bicuspid aortic valve, a rare congenital condition.
Observation:
- Echocardiography revealed thickened, calcified aortic leaflets with moderate aortic regurgitation.
- The bicuspid valve lacked the typical "Y" sign seen in tricuspid valves.
- No carotid stenosis or signs of endocarditis were detected.
Findings:
- The calcified aortic valve leaflets were identified as the probable source of the retinal embolism.
- Despite moderate regurgitation, the valve was not stenotic.
Implications:
- This case highlights a potential link between calcified bicuspid aortic valves and embolic events, even without significant stenosis.
- Anticoagulant therapy was initiated due to the embolic event, while aortic valve replacement was deemed unnecessary at this time.
