Hypothesis
What is the rate of silent cerebral infarction after cardiac catheterization, and how does the arterial access site affect this rate?
Conclusion
The study aims to assess the occurrence of silent cerebral infarction after cardiac catheterization and compare the effects of radial versus femoral access.
Supporting Evidence
- Cerebral microembolism occurs during cardiac catheterization.
- Asymptomatic embolic cerebral infarction might occur in 15 to 22% of cases.
- The study will use diffusion-weighted MRI to assess silent cerebral infarction.
Takeaway
Doctors want to find out if using different entry points for heart procedures can cause hidden brain injuries.
Methodology
This is a prospective multicenter randomized trial involving patients with severe aortic valve stenosis who will undergo DW-MRI and neurological assessments before and after cardiac catheterization.
Limitations
Exclusion criteria include contraindications to MRI or inability to give informed consent.
Participant Demographics
Patients with severe aortic stenosis scheduled for cardiac catheterization.
Statistical Information
Confidence Interval
5.9% [0.01–12.5; 95% CI] for radial approach; 23% [15–31; 95% CI] for femoral approach.
