Data are presented as median [interquartile range] or number (%); LVDd, left ventricular internal diameter in diastole; LVDs, left ventricular internal diameter in systole; LVEF, left ventricular ejection fraction; LVMI, left ventricular mass index; AVA, aortic valve area; AVAi, aortic valve area index; EOA, effective orifice area; EOAi, effective orifice area index; Patient-prosthesis mismatch (PPM): severe PPM means EOAi < 0.65 cm2/m2
