Vrot,AsAo = rotational velocity at the ascending aorta; Vrot,avg = averaged rotational velocity in the thoracic aorta; Vjet,peak = peak velocity of the jet flow at the impinging region; Vgoa,peak = peak velocity of the jet flow at the exit of the aortic valve; Ajet = area of the jet at the impinging region; Agoa = area of the jet flow at the exit of the aortic valve; Q = flow rate; Pimp = estimated impinging pressure; N = number of elements.

*Statistically different (p < 0.01) in comparison with TKE in straight aortic valve flow.

Statistically different (p < 0.01) in comparison with TKE in the same aortic flow direction, but at 15° of the aortic valve flow. Data indicates the mean ± SD.
