Abstract: Proper blood flow through the atrioventricular heart valves (AHVs) relies on the holistic function of the valve and subvalvular structures, and a failure of any component can lead to life-threatening heart disease. A comprehension of… read more here.

DOI: 10.1007/s11548-020-02230-y
Abstract: Purpose Decision support systems for mitral valve disease are an important step toward personalized surgery planning. A simulation of the mitral valve apparatus is required for decision support. Building a model of the chordae tendineae… read more here.

DOI: 10.1038/s41598-018-35555-5
Abstract: Mitral valve (MV) dynamics depends on a force balance across the mitral leaflets, the chordae tendineae, the mitral annulus, the papillary muscles and the adjacent ventricular wall. Chordae rupture disrupts the link between the MV… read more here.

DOI: 10.1111/jocs.17194
Abstract: The chordae tendinae connect the papillary muscles (PMs) to the mitral valve. While the first‐order chordae serve to secure the leaflets to maintain valve closure and prevent mitral valve prolapse, the second‐order chordae are believed… read more here.

DOI: 10.1115/1.4044142
Abstract: Abstract Few technologies exist that can provide quantitative data on forces within the mitral valve apparatus. Marker-based strain measurements can be performed, but chordal geometry and restricted optical access are limitations. Foil-based strain sensors have… read more here.
