Baseline Characteristics	Before TAVI	After TAVI	P value
LVEF(%)	62.6 (55.0, 67.0)	64.5 (61.0, 67.0)	0.43
TTE Aortic annulus diameter (mm)	23.0 (21.0, 24.0)	26.0 (23.0, 26.0)	0.021
TTE Aortic valve area (cm2)	0.86 (0.82, 0.90)	1.78 (1.72, 1.80)	<0.001
EOAI	0.52 (0.49, 0.53)	1.06 (1.01, 1.12)	<0.001
Jet velocity (cm/s)	510 (456, 542)	205 (186, 236)	<0.001
NYHA functional class ≥ II, yes, n (%)	10 (100)	2 (20)	<0.001

Data were presented as median (IQR) or n (%).

EOAI=effective disc mouth area index; NYHA=New York Heart Association; LVEF=left ventricular ejection fraction; TTE=transthoracic echocardiography
