*: 0 means that TEE evaluation was inaccurate, 1 not optimal and 2 optimal [see ref (5)].
Abbreviations: SVC: respiratory variations of superior vena cava, E/A: ratio of maximal velocity of mitral E and A waves, LVFAC: left
ventricular fractional area change, VTI: velocity time integral of LV outflow tract Doppler velocities.
