Evaluation of vorticity, helicity and eccentricity of blood flow: The upper row shows the frequency of each score for the various AVR groups and controls. The lower row depicts the mean ± SD scoring results. Please note that the order of the groups varies between the three columns. (* p<0.05 vs. stentless, autografts and controls; † p<0.05 vs. stentless, autografts and controls; ‡ <0.05 vs. controls; $ p<0.05 vs. stented, autografts, controls; | |p<0.05 vs. stentless, mechanical, autografts and controls)
