BAV vs TAV Streamlines

Comparative visualization of streamlines for bicuspid and tricuspid aortic valves showing the differences in flow patterns.

1 Challenge

Comparing flow patterns between bicuspid and tricuspid aortic valves.

2 CFD Approach

Computed instantaneous streamlines colored with velocity magnitude contours for both BAV and TAV cases.

3 Results

For BAV, the valve jet undergoes a significant change in orientation causing it to impinge on the ascending aorta wall. This impingement is associated with the eccentricity of the BAV.

4 Engineering Conclusion

BAV increases the shear stress on the wall of the ascending aorta compared to TAV.
