TA-TAVI, transapical transcatheter aortic valve implantation; C-AVR, conventional aortic valve replacement; LVEF, left ventricular ejection fraction; LVEDD, left ventricular end-diastolic dimension. Generalized estimating equation models were used. ^aNon-normally distributed variables are presented as median (interquartile range (IQR)) and categorical data as numbers.
