Values are presented as mean ± standard deviation or %. *, data in entire group before propensity-score matching; ^†, median with interquartile range; ^‡, median with range; ^§, because this study was from the same registry as the study by berretta et al., it was only used to extract data regarding aortic valve mean pressure gradient in each valve size, which the former did not report; ^#, logistic EuroScore. AVR, aortic valve replacement; BMI, body mass index; BSA, body surface area; RD, rapid deployment; SU, sutureless.
