FLUID-STRUCTURE INTERACTION SIMULATION OF THE EDGE-TO-EDGE REPAIR OF THE MITRAL VALVE IN FUNCTIONAL AND DEGENERATIVE STATES

摘要

The ETER restores function to the valve in closure (systole), however in opening (diastole) the function of the valve and the fluid are both altered. Increases in the stress magnitude are doubled, with the distribution of stress is shifted to the location of the correction. In normal scenarios the MV regulates the flow rate by deforming freely to adapt to the required flow rate. The ETER of the valve impairs the valve's ability to deform freely, thus reducing the flow rate throughout the diastolic simulation and shifting the peak maximum flow rate.
