Mismatch stands for prosthesis–patient mismatch, defined as a ratio of the prosthesis's effective orifice area over the patient's body surface area equal to or less than 0.85 cm2/m2. p Values refer to the comparison between mismatch and no-mismatch patients within the age groups. Data are reported as median (IQR).
EDD, end-diastolic dimension; ESD, end-systolic dimension; FS, fractional shortening; IVS, thickness of interventricular septum; LVM, LV mass; LVMI, indexed LV mass.
