Follow-up Doppler echocardiographic data in the whole cohort, grouped by different methods.

Variable	Post-TAVI		P-value
	Method 1	Method 2
Data are presented as means ± SD or n (%). EI: eccentricity index; EOA: effective orifice area; EOAI: indexed effective orifice area; LVOT: left ventricular outflow tract; LVOTd: left ventricular outflow tract diameter; PPM: prosthesis-patient mismatch; TAVI: transcatheter aortic valve implantation; VTILVOT: velocity-time integral of the left ventricular outflow tract.
