  • Continuous variables are represented as mean (SD) and median (IQR); p values are from paired samples t-test (normal distribution) and Wilcoxon signed-rank test (non-normal distribution).

  • AVO, aortic valve opening; IQR, interquartile range ; RPM, revolutions per minute; SD, standard deviation.
