This study, titled 'State-space formulations to understand the nonlinear viscoelastic mechanical behavior of tricuspid valve chordae tendineae," investigates the complex mechanical behavior of tricuspid valve chordae tendineae using state-space representations of nonlinear viscoelastic models. By capturing time-dependent and nonlinear stress-strain relationships, the authors provide a framework for simulating chordae dynamics under physiological loading. This approach enhances modeling accuracy for heart valve mechanics and supports future development of patient-specific simulations and surgical planning tools.
