Project
Bicuspid Aortic Valve Q-criterion
Q-criterion visualization showing vortex structures in bicuspid aortic valve flow. Demonstrates abnormal flow patterns compared to trileaflet valves.
1 Challenge
Understanding the abnormal flow patterns in bicuspid aortic valve compared to trileaflet valves.
2 CFD Approach
Iso-surfaces of the Q-criterion for a bicuspid aortic valve during systolic phase. Linear isotropic Saint-Venant material model was used.
3 Results
The aortic valve vortex ring grows in complexity rapidly and breaks into turbulence much sooner than for the trileaflet case.
4 Engineering Conclusion
BAV shows significantly different flow patterns that may contribute to aortic wall stress.
