Computational Modeling of the Subject-Specific Effects of Annuloplasty Ring Sizing on the Mitral Valve to Repair Functional Mitral Regurgitation

Impact of tricuspid annuloplasty device shape and size on valve mechanics—a computational study

“…Figure 2 shows all 4 annuloplasty devices used in this study. Note all devices are considered “rigid” or “stiff.” 19 The exact geometries of the devices were determined via 3D scanning 20 ; device areas and heights are provided in Table 1 . The virtual repairs themselves were conducted using Abaqus/Explicit, in which we simulated first the device implantation and then the post-repair valve closure.…”
