Key result

The 3D geometrical model estimated a peak shear stress of 13.31 Pa at 80% stenosis compared to 10.09 Pa in the 2D model, indicating 3D models are more suitable for analyzing severe disease conditions.

Overview

3D models may better estimate shear stress in severe stenosis; leaves open clinical translation and validation in human outcomes.

Shanmugavelayudam et al. (2010) studied Coronary heart disease. 3D geometrical model vs. 2D geometrical model was evaluated on Peak shear stress at the stenosis throat. The 3D geometrical model estimated a peak shear stress of 13.31 Pa at 80% stenosis compared to 10.09 Pa in the 2D model, indicating 3D models are more suitable for analyzing severe disease conditions.
