Evaluating Novel Annuloplasty Ring Designs in a Pathophysiological Animal Model
Results demonstrate trends in suture forces and their spatial variation. COM-Flex was most effective in distributing forces away from posterior annulus. Despite POST-Flex having large material heterogeneity, average posterior force was similar to rigid rings. Results shown in this study provide an atlas of data on how variable annular loading is and the complexity of both understanding loads and developing devices to sustain them.
