AV, aortic valve; AVA, aortic valve area; AVPG, aortic valve pressure gradient; BNP, B‐type natriuretic peptide; LVEDV, left ventricular end‐diastolic volume; LVEF, left ventricular ejection fraction; LVESV, left ventricular end‐systolic volume; PASP, pulmonary artery systolic pressure.
Continuous data are presented as means ± standard deviations, except BNP (median and interquartile range).
