Data are presented as mean±SD, no. (%), or median (Q1, Q3). The number of patients with available echocardiographic studies at 6 and 12 months is mentioned in the table. AV indicates aortic valve; AVA, aortic valve area; LV‐SVI, left ventricular stroke volume index; RVSP, right ventricular systolic pressure; SAVR, surgical transcatheter aortic valve replacement; TAVR, transcatheter aortic valve replacement.
