Values are mean±SD or median (interquartile range).

ANOVA repeated measure overtime with procedure as covariate. Paired t test vs baseline: *p<0.05, **p<0.01, ***p<0.001.

AR, aortic regurgitation; EDVI, end diastolic volume indexed to body surface area; EF, ejection fraction; ESVI, end systolic volume indexed; LV, left ventricle; LVM, left ventricular mass; mean PG, peak pressure gradient; MR, mitral regurgitation; RV, right ventricle; SVI, stroke volume indexed; TAVI, transcatheter aortic valve implantation.
