| 目的 探讨以3D-经食管超声心动图（TEE）为数据源，采用3D打印技术制作二尖瓣（MV）模型的可行性。方法 获取30例患者的MV 3D-TEE图像，其中MV正常、MV狭窄、MV脱垂各10例，使用铸模硅胶灌注成型法制作MV 3D模型。测量并对比3D模型及3D-TEE图像上二尖瓣前后径、前外后内侧径、瓣环周长、瓣环面积及瓣膜开放幅度，计算二者间MV上述测值的绝对差值。结果 30例3D-TEE图像均成功后处理并打印制作出MV 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均>0.05），且各参数测值的绝对差值均较小。结论 采用3D-TEE和3D打印技术制作MV模型可行，且具有高保真度。 |

| Objective To explore the feasibility of using 3D transesophageal echocardiography (3D-TEE) data to generate 3D patient-specific model of mitral valve (MV) using 3D printing. Methods A retrospective study was performed in 30 patients, including 10 cases with normal MV, 10 cases with MV stenosis and 10 cases with MV prolapse. 3D-TEE volumetric data of 30 patients were acquired and postprocessed, and then soft MV models were made through injecting silicone into the molds. Measurements of MV annulus antero-posterior diameters, anterolaterior and posteromedial diameters, perimeter, area and MV opening width obtained from 3D-TEE images and from 3D models were compared, and the absolute differences of these values were calculated. Results 3D-TEE volumetric data were successfully postprocessed, and then 3D MV models were made in all patients. The differences of MV parameters measured from 3D models were not statistically significant with those from 3D-TEE images (all P>0.05). Only less absolute differences of MV parameters were found between 3D models and 3D-TEE images. Conclusion 3D printing of MV models based on 3D-TEE is feasible with high conserved fidelity. |
