| 目的：应用经食管超声心动图数据重建并打印左心耳3D模型并分析其准确性。方法：选取于医院就诊并接受三维经食管超声心动图（3D-TEE）及心脏增强CT检查的患者20例，对其3D-TEE 左心耳数据进行后处理并使用软质类橡胶材料打印3D实体模型，测量左心耳模型的开口长径、短径、深度并进行解剖分型评估，将其与3D-TEE、CT的结果进行对比。结果：3D模型组与3D-TEE组的左心耳开口长径、开口短径、深度差异均无统计学意义（均P >0.05），组间ICC分别为0.97、0.98、0.98；CT组的左心耳开口长径、开口短径、深度测值均大于3D-TEE组（均P <0.05），组间ICC分别0.91、0.88、0.90。3D模型组与CT组在左心耳评估形态、分叶差异均无统计学意义（均P >0.05）；Kappa值分别为0.86、0.91（均P <0.05）。3D-TEE组与CT组在左心耳评估形态、分叶差异均无统计学意义（均P >0.05）；Kappa值分别为0.71、0.81（均P <0.05）。结论：基于经食管超声数据左心耳3D打印模型的测量径线可准确还原其数据源；与3D-TEE相比，左心耳3D模型在评估形态及分叶方面与CT重建一致性更高。 |

| Abstract: |
| Objective To analyse the accuracy of the left atrial appendage(LAA) 3D printing model based on the transesophageal echocardiography.Methods 3D-transesophageal echocardiography(3D-TEE) and contrast-enhanced cardiac CT were both performed on 20 patients. The 3D-TEE data of LAA were post-processed, and printed with soft rubber-like materials.The long axis and short axis of LAA ostium, and depth of LAA were measured and anatomical classification was evaluated.3D-TEE and CT were compared with the results of 3D printing model. Results Compared with the long axis,short axis and depth of LAA ostium measured in 3D-TEE group, the measurement in 3D printing model group had no significant difference(both P>0.05)(ICC:0.97,0.98,0.98), while CT group had larger measurement(both P<0.05)(ICC:0.91,0.88,0.90).3D printing model group and CT group had no significant difference in evaluating the shape and lobulation of LAA(both P>0.05),and the kappa values were 0.86,0.91(both P<0.05).Also 3D-TEE group and CT group had no significant difference in evaluating the shape and lobulation of LAA(both P>0.05),while the kappa values were 0.71,0.81(both P<0.05). Conclusion The measurment of LAA 3D printing model based on 3D-TEE can accurately restore its data.Compared with 3D-TEE, 3D printing model is more consistent with CT reconstruction while evaluation the morphology. |
