Amax: peak velocity of the mitral flow during the atrial contraction, Amean: mean velocity of the mitral flow during the atrial contraction, CV: Coefficient of variation, Dec: Deceleration, Emax: peak velocity of the mitral flow during the early ventricular filling, Emean: mean velocity of the mitral flow during the early ventricular filling, ET: Ejection time, LSMean: Least Square Mean, SD: Standard deviation, SE: Standard error, VTI: Velocity time integral.

* Significantly different from corresponding value obtained from the right side, p < 0.05.
