Values are shown as median (interquartile range) for continuous variables and number (percentage) for categorical variables. Group differences are presented as overall P value. PVL indicates paravalvular leakage; ViSAVR, valve in surgical aortic valve replacement; ViTAVR, valve in transcatheter aortic valve replacement; and ViV, valve‐in‐valve.
