“…A complete account of all model details, including the geometry, material properties, and boundary conditions, can be found in Appendix E1 and our recent work. 14 To investigate the impact of device shape and size on the mechanics of the diseased, ie, regurgitant, tricuspid valve, we altered our published healthy valve model to mirror the pathology of pulmonary arterial hypertension-induced functional tricuspid regurgitation. As such, we asymmetrically dilated the tricuspid annulus in the lateral direction until achieving an end-diastolic annular area increase of 62% and an annular circularity of one.…”
