二尖瓣修复和采用的进步部分归功于超声心动图成像技术的改进。为了进一步教育和指导修复手术，我们开发了一种方法，使用新型 3D 超声心动图成像软件与立体光刻打印相结合，快速生成瓣膜的物理模型。使用基于半自动图像分割和连续内侧表示 (cm-rep) 算法的软件，根据 3D 经食管超声心动图图像开发定量虚拟二尖瓣形状模型。然后将这些定量虚拟形状模型用作市售立体光刻打印机的输入，以生成收缩末期和舒张末期每个瓣膜的物理模型。构建了正常和患病瓣膜（缺血性二尖瓣反流和粘液瘤变性）的物理模型。虚拟形状模型和物理模型之间具有良好的对应性。使用 3D 超声心动图数据的 3D 打印，可以在正常、缺血和粘液性瓣膜条件下创建二尖瓣几何形状的物理模型。打印瓣膜有潜力指导二尖瓣疾病的手术治疗。
Advances in mitral valve repair and adoption have been partly attributed to improvements in echocardiographic imaging technology. To further educate and guide repair surgery, we have developed a methodology to quickly produce physical models of the valve using novel 3D echocardiographic imaging software in combination with stereolithographic printing. Quantitative virtual mitral valve shape models were developed from 3D transesophageal echocardiographic images using software based on semi-automated image segmentation and continuous medial representation (cm-rep) algorithms. These quantitative virtual shape models were then used as input to a commercially available stereolithographic printer to generate a physical model of the each valve at end systole and end diastole. Physical models of normal and diseased valves (ischemic mitral regurgitation and myxomatous degeneration) were constructed. There was good correspondence between the virtual shape models and physical models. It was feasible to create a physical model of mitral valve geometry under normal, ischemic and myxomatous valve conditions using 3D printing of 3D echocardiographic data. Printed valves have the potential to guide surgical therapy for mitral valve disease.
