2 Fig 1 Schematic showing details of study population, design, and endpoints. (AVR = aortic valve replacement; DW-MRI = diffusion-weighted magnetic resonance imaging; EuroSCORE = European system for cardiac operative risk evaluation; STS = The Society of Thoracic Surgeons; TAVI = transcatheter aortic valve implantation; TCD = transcranial Doppler.)
