Why the study?
Mitral repair with annuloplasty ring implantation is the most efficient surgical intervention for MR, but patient-specific simulation protocols are needed to evaluate functional improvement.
Does virtual finite element-based ring annuloplasty simulation predict functional improvement and stress reduction in a patient with mitral annular dilation?
Does virtual finite element-based ring annuloplasty simulation predict functional improvement and stress reduction in a patient with mitral annular dilation?
A novel finite element-based patient-specific mitral valve repair simulation can effectively evaluate and predict functional improvement following ring annuloplasty.

Patient-specific simulation may aid mitral repair planning; extends finite element modeling to predict annuloplasty outcomes in annular dilation.
Choi et al. (2014) studied Mitral annular dilation with mitral regurgitation (n=1). Virtual ring annuloplasty simulation vs. Pre-annuloplasty was evaluated on Stress distribution across the mitral valve leaflets and annulus and leaflet coaptation. Virtual patient-specific ring annuloplasty simulation demonstrated markedly reduced stress distribution across the mitral valve leaflets and annulus and restored leaflet coaptation.
