Abstract
Mitral valvular heart disease is one of the major causes of morbidity and mortality all over the world. The optimal surgical strategy of treatment of valvular heart disease is repair or replacement. There is still ongoing research for optimal valve replacement options. Creation of new valve prosthesis is still a pressing problem. It is not enough information in publications about biomechanical properties of human mitral valve. We performed experimental studies of biomechanical properties of mitral valves on pathologically unchanged human heart valves, taken from 4 cadaveric hearts. Mitral valve construction elements were investigated using uniaxial tensile tests. It was established that an anterior chordae modulus of elasticity (477.28±2 4.322 MPa), is greater than the one of anterior and posterior leaflet (43.48 ± 15.97 MPa and 6.36 ± 3.15MPa, respectively). These results correspond to previously published reports. Future valve sample radial direction investigations will provide more detailed information about it.
