Based on the stress solutions, it was shown how design curves could be obtained to guide the selection of dimensions and materials for the preparation and restoration of this class of cavities. The cavity wall was considered as a cantilevered beam while the resin composite was modeled as Winkler's elastic foundation with closely-spaced linear springs. Further, a mathematical model that took into account the combined effect of material properties, sample geometry and compliance of the surrounding constraint was employed to relate the shrinkage stress at the "tooth-composite" interface to the local compliance of the cavity wall. Exact analytical solutions were obtained for cuspal deflection and shrinkage stress along the cavity wall by solving the resulting diffesed by polymerization shrinkage. The study objective was to evaluate the midterm outcomes of transventricular mitral valve repair and its association with the initial anatomy of the mitral valve. This nonrandomized observational study included 88 patients (mean age, 60years; 69% were men) who underwent transventricular mitral valve repair for severe degenerative mitral regurgitation between 2011 and 2017. Mitral valve function was assessed by echocardiography at 1 and 6months and annually after the procedure. According to the location of mitral valve pathology, all patients were stratified into 4 anatomic types (A, B, C, and D). Results were assessed using Kaplan-Meier method, mixed-effects continuation ratio model, and multivariable Cox regression. Median follow-up of 42months (interquartile range, 27-55) was complete for 83 patients (94.3%). There were 3 late deaths 2 cardiac and 1 noncardiac. Recurrent
