Values are mean ± (SD), n (%), or median (25th to 75th interquartile range), unless otherwise noted.

EuroSCORE = European system for cardiac operative risk evaluation; NYHA = New York Heart Association functional class; SAVR = surgical aortic valve replacement; STS = Society of Thoracic Surgeons; TAVI = transcatheter aortic valve implantation.
