'Significant stroke risk' in TAVR for bicuspid aortic stenosis

Stroke prevention strategies need to be considered for such patients, researcher says

Patients undergoing transcatheter aortic-valve replacement (TAVR) of bicuspid aortic valves could be at considerable risk of stroke even when treated at high-volume centres, researchers say.
