Annular geometric parameters are summarized. Data are presented as mean ± standard error of the mean for the cohort.

b

p < 0.05 compared with baseline value.

AH = annular height; AHCWR = global annular height to commissural width ratio; CW = intercommissural width; MAA = mitral annular area; SL = septolateral diameter.
