| #Standardised β coefficient for age <70 from a linear regression model fitted with mean AVG as the dependant variable and THV type as covariate. *OR for moderate+ PVL for age <70 from a logistic regression model fitted with moderate+ PVL as the outcome variable and THV type as covariate. AVG: aortic valve gradient; BAV: bicuspid aortic valve; PVL: paravalvular leak; THV: transcatheter heart valve; ViV: valve-in-valve | |||||||||
