Gaseous microemboli from prosthetic aortic valve cavitation were visualized in cerebral arteries using transcranial Doppler and B-mode sonography. This marks the first report of microemboli flow visualized in B-mode imaging.
Area of Science:
- Neurology
- Cardiology
- Medical Imaging
Background:
- Mechanical prosthetic aortic valves can be associated with embolic events.
- Transient amnesia can be a symptom of cerebral microembolic events.
- Cerebral microemboli detection is crucial for understanding neurological events.
