People with bicuspid aortic valves who underwent transcatheter aortic valve replacement had more new cerebral ischemic lesions with larger sizes and elevated volumes in imaging scans, compared with those with tricuspid aortic valves, according to a study in the Journal of the American College of Cardiology. "Cerebral embolic protection devices may be recommended for TAVR, especially in BAV patients, to avoid cerebral ischemic lesions that potentially deteriorate neurological and cognitive function," researchers wrote.
