Values are presented as number of patients (%) or mean±standard deviation.

EOA = effective orifice area; EOAI = effective orifice area index; PVL = paravalvular leakage; TAVR = transcatheter aortic valve replacement; THV = transcatheter heart valve.

^*Patients who underwent valve-in-valve procedure (n=5) were excluded from mean EOA/EOAI calculation.
