Key result
A finite element model of the aortic root showed maximum principal stresses of 759, 613, and 603 kPa on the non-coronary, right, and left leaflets, respectively, at maximum transvalvular pressure.
A novel MRI-derived finite element model of the aortic root realistically captures biomechanical stress and strain patterns, providing a potential tool to optimize surgical procedures.

May guide aortic valve surgical planning; leaves open prospective clinical validation of stress predictions.
Conti et al. (2010) studied Healthy (n=10). Finite element (FE) model of the physiological aortic root was evaluated on Stress and strain patterns. A finite element model of the aortic root showed maximum principal stresses of 759, 613, and 603 kPa on the non-coronary, right, and left leaflets, respectively, at maximum transvalvular pressure.
