Biomechanical modeling of the tricuspid valve using fluid-structure interaction method

Year: 2025

Type: article

Abstract: The tricuspid valve (TV) separates the right ventricle from the right atrium, and biomechanical analysis of the tricuspid valve is a major topic in the biomechanics of the cardiovascular system. It provides insight into the prevention and curing of heart diseases related to tricuspid. In this study, we introduced an advanced three-dimensional model for investigating the mechanical behavior and hemodynamic efficiency of the tricuspid valve under physiological conditions using the fluid-structure interaction method (FSI). The geometry of the valve was reconstructed from CT and anatomical data to provide a precise leaflet and chordae tendineae representation. We used three models to characterize the complex nonlinear mechanical response of the valve soft tissue: the isotropic elastic model, the third-order Ogden model, and the visco-hyperelastic model. The results, including the shear stresses and the leaflet deformations, were presented and validated. Our model is a pioneer in analyzing the tricuspid (TR) biomechanics.
