Although finite element analysis has been used to model simple mitral repair, it has not been used to model complex repair. A virtual mitral valve model was successful in simulating normal and abnormal valve function. Models were then developed to simulate an edge-to-edge repair and repair employing quadrangular resection. Stress contour plots demonstrated increased stresses along the mitral annulus, corresponding to the annuloplasty. The role of finite element analysis in guiding clinical practice remains undetermined.
虽然有限元分析已被用于对简单的二尖瓣修复进行建模，但尚未用于对复杂修复进行建模。一个虚拟二尖瓣模型成功地模拟了正常和异常的瓣膜功能。然后开发了模型来模拟边缘对边缘修复和采用四边形切除术的修复。应力等高线图显示二尖瓣环处的应力增加，与瓣环成形术相对应。有限元分析在指导临床实践中的作用仍未确定。
