采用多物理场左右心室（RV/LV）流固耦合（FSI）模型进行机械应力分析，评价贴片材料对左心室功能的影响。FSI模型包括三种不同的贴片材料（涤纶支架、处理心包和收缩心肌）、两层结构、纤维取向和活性各向异性材料特性。该模型是基于从严重右心室扩张患者获得的心脏磁共振（CMR）图像构建的，并通过ADINA解决。结果表明，心肌收缩的膜片模型可降低膜片区应激水平，改善右心室功能和膜片区收缩力。
Multi-physics right and left ventricle (RV/LV) fluid-structure interaction (FSI) models were introduced to perform mechanical stress analysis and evaluate the effect of patch materials on RV function. The FSI models included three different patch materials (Dacron scaffold, treated pericardium, and contracting myocardium), two-layer construction, fiber orientation, and active anisotropic material properties. The models were constructed based on cardiac magnetic resonance (CMR) images acquired from a patient with severe RV dilatation and solved by ADINA. Our results indicate that the patch model with contracting myocardium leads to decreased stress level in the patch area, improved RV function and patch area contractility.
