Article Synopsis
- Accurate imaging shows that the aortic annulus diameter varies during the cardiac cycle, which is important for TAVR surgery planning.
- The study investigates how fixing the aortic annulus affects valve function by comparing two computational models: one simulates a dynamic annulus and the other a fixed one.
- Results indicate that a dynamic annulus boosts blood flow, velocity, and kinetic energy, while also effectively stabilizing flow and reducing pressure needed to keep the valve open, highlighting the importance of considering the annulus's dynamic nature.
