Risk factor of SBI
In the univariate analysis, age and aortic stenosis were considered the risk factors of SBI. Meanwhile, the multivariate analysis revealed that aortic stenosis was a risk factor. In aortic valve replacement for aortic valve stenosis, the possible cause of embolic lesions is the presence of debris generated when resecting aortic valves, and these debris may be responsible for brain infarcts, including emboli, after releasing the aortic clamp.
