Continuous variables are presented as mean (SD) or median (LQ–UQ), when indicated; categorical ones are represented as n (%).
AS, aortic stenosis; AVA, aortic valve area; AVmax, aortic valve velocity maximum; BP LVEF, two-dimensional biplane left ventricular ejection fraction; LQ, lower quartile; LVMi, left ventricular mass indexed to BSA; MR, mitral regurgitation; TR Pmax, tricuspid regurgitation gradient; UQ, upper quartile.
