Implication

Requires leaflet-to-chordae contact in mitral valve models to avoid underestimating regurgitant orifice area; extends computational fidelity but leaves clinical translation open.

Population

2 computational virtual mitral valve (MV) models created using 3D transesophageal echocardiography data from 2 patients (1 with normal MV without mitral regurgitation, 1 with pathologic MV with mitral regurgitation)

Intervention

Computational dynamic finite element simulation of MV function incorporating full leaflet-to-chordae contact interaction

Comparator

Computational MV simulation without leaflet-to-chordae contact interaction (leaflet-to-leaflet contact only)

Outcome

Degree of leaflet coaptation and physical realism of contact interactions during systolesurrogate

Incorporating leaflet-to-chordae contact interactions in computational mitral valve models is essential for accurately quantifying leaflet coaptation and the severity of mitral regurgitation.

Limitations

Utilized previously published material characteristic data
Assumed homogeneous thickness and material behavior of MV tissue
Purely structural analysis without fully incorporating blood fluid effects on normal and shear pressure distribution
