  1. Values are mean ± SD or median (interquartile range). LGE indicates late gadolinium enhancement.
  2. *p < 0.05 vs pre AVR and >0.05 vs normal; †p > 0.05 vs pre AVR and normal; ‡p < 0.05 vs pre AVR and normal; **p < 0.05 vs pre AVR; ***p > 0.05 vs pre AVR. LGE data were based on n = 14 who had LGE + .
