| 目的 探讨应用经食道三维超声心动图和3D打印技术制作二尖瓣模型的可行性。方法 获取30例患者二尖瓣3D-TEE图像，其中正常二尖瓣、二尖瓣狭窄、二尖瓣脱垂各10例，使用铸模硅胶灌注成形的方法制作二尖瓣3D模型。测量3D模型上的二尖瓣前外后内侧径、前后径、瓣环周长、瓣环面积及瓣膜开放幅度，并与3D-TEE图像上的测值进行对比。计算两者间二尖瓣各参数测值的绝对差值。结果 30例患者的3D-TEE图像均成功后处理并打印制作出二尖瓣3D模型，3D模型与3D-TEE图像间各参数测值差异均无统计学意义（P＞0.05），且两者间各参数测值的绝对差值均较小。结论 应用3D-TEE为数据源，结合3D打印技术制作二尖瓣模型具有较高地可行性，在二尖瓣膜病的临床教学、手术决策及手术演练上有广泛的应用前景。 |

| Objective To explore the feasibility of using transesophageal 3D echocardiography (3D-TEE) data to generate 3D patient-speci?c models of mitral valve (MV). Methods A retrospective study was performed in 30 patients, including 10 cases with normal mitral valve,10 cases with mitral valve stenosis,10 cases with mitral valve prolapse.3D-TEE volumetric data of 30 patients were acquired and postprocessed, and then the soft MV models were made by injecting silicone to the molds. Measurements of the MV annulus antero-posterior diameters , anterolaterior and posteromedial diameters, perimeter , area and MV opening width obtained from the 3D echo data set were compared with those performed on the 3D models, From which the absolute difference of the measurements between 3D models and the 3D echo data were calculated. Results 3D-TEE volumetric data were successfully postprocessed and made as 3D MV models in all patients. The differences of the MV parameters measured using the 3D models were not significant from those measured on the 3D echo data (all P>0.05). It showed little absolute difference in value of the MV parameters between the 3D models and the 3D-TEE images. Conclusion The MV models made by 3D-TEE and 3D printing technique is feasible with highly conserved ?delity, This technique has the potential for rapid integration into clinical practice to assist with decision-making, surgical planning, and teaching. |
