<Jorge Hernan Jimenez> is a biomedical-engineering researcher whose primary publications investigate the mechanics of the <mitral valve> and its supporting <chordae tendineae>. His 2005 first-author study lists the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory as the affiliation for that work.<Effects of papillary muscle position on chordal force distribution: an in-vitro study by Jorge Hernan Jimenez and others>[Primary byline and affiliation]{ref}
The experiment connected valve geometry to measured forces. Jimenez and colleagues placed six human and five porcine mitral valves in a physiological left-heart simulator, recorded cardiac output and transmitral pressure, and fitted force transducers to six chordae. They tested eight papillary-muscle positions constructed from $5\,\mathrm{mm}$ vector displacements from the normal position. The tension response depended on chordal type: marginal chords were comparatively insensitive, while other classes showed larger changes.<Effects of papillary muscle position on chordal force distribution: an in-vitro study by Jorge Hernan Jimenez and others>[Abstract, Methods, Results and Conclusion]{ref}
The scientific point is that moving a support does not change every tether's load in the same way. In an idealized mechanical representation, a chordal force is $\mathbf F_i=T_i\mathbf u_i$, with tension $T_i$ and direction $\mathbf u_i$. Moving its attachment can change both. A change in one measured tension therefore does not, by itself, determine the complete resultant load or leaflet motion; several forces and the valve geometry must be considered together.
The simulator allowed a controlled geometric perturbation while observing forces during the cardiac cycle. It supports an in-vitro mechanical relationship under the stated conditions, rather than a universal prediction of clinical outcome from one displacement. The verified full byline is retained without attaching an unverified career history or namesake portrait.
