我们描述了一种进行建模和模拟的方法，以预测重建心胸手术所产生的组织所经历的应变和应力。应力计算是修复质量和寿命的重要预测因素，因此可以作为外科医生在各种修复选项之间做出决定时的指导。本文使用二尖瓣修复作为用例，因为它在重建心脏干预中具有相关性和普遍性。这里介绍的建模方法是根据从实时 3D 超声心动图恢复的患者特定解剖结构而得出的。该方法利用超弹性模型来推断真实的应变应力。我们通过使用实际临床数据的实验表明，结果符合生理预期。
We describe a method for performing modeling and simulation to predict the strain and stress experienced by tissues resulting from reconstructive cardiothoracic surgery. Stress computation is an important predictor of the quality and longevity of a repair and can therefore be used as guidance by a surgeon when deciding between various repair options. This paper uses the mitral valve repair as a use case because of its relevance and prevalence among reconstructive cardiac interventions. The modeling method presented here is informed by the patient specific anatomical structure recovered from real time 3D echocardiography. The method exploits hyperelastic models to infer realistic strain-stresses. We show through experiments using actual clinical data that results are in line with physiological expectations.
