Abstract :
Experimental measurements of mitral valve deformation were performed in isolated pig hearts. Markers placed on the anterior and posterior leaflets were imaged, and biaxial stretch calculated. Results show that the leaflets undergo large deformation, most of which occurs in the low pressure range. Differences in the deformation pattern from previous biaxial data may be attributed to the additional structural tethering of the chordae tendineae
