摘要： 目的 通过多元统计和社会网络分析法中关键词共现的方式，研究中国先天性心脏病（CHD）介入诊断治疗的学科知识分布，研究学科知识聚类，并预测未来发展趋势。 方法 2011年3月以主题词“心脏缺损，先天性”和“心脏导管插入术”在中国生物医学文献数据库(CBM)检索文献;使用Endnote X4软件提取关键词，建立共词矩阵；使用SPSS 17.0软件对共现矩阵进行转换、降维和聚类分析，并根据聚类分析结果绘制战略坐标图；使用Ucinet 6.0软件绘制可视化网络。 结果 共命中文献1 015篇。成功建立中国CHD介入诊断治疗学科知识可视化图谱，直观展示了中国CHD介入诊断治疗学科的知识分布，并形成重点研究聚类，提示治疗，方法和设备，超声心动图等学科知识发展较好。 结论 中国CHD学科知识以治疗聚类为中心，且多学科知识聚类共同发展；同时材料和设备的相关研究在CHD学科发展中具有显著推动作用，超声心动图及肺动脉高压在CHD学科知识中地位重要。

Abstract: Objective To study the subject domain knowledge of interventional diagnosis and therapy of congenital heart disease (CHD) in our country using multiple statistical and social network analysis, and finally build visualized knowledge-mapping. Methods The China Biology Medicine disc (CBM) using MeSH keywords "heart defect, congenital" and "cardiac catheterization" in March 2011 was searched. After core keywords had been characterized by Endnote X4, the co-occurrence matrix was built. Transformation, dimensionality reduction and clustering of the co-occurrence matrix were finished by SPSS 17.0 software, leading the strategic plot to be built.Then visualized network was drawn using Ucinet 6.0 software. Results The searching results included 1 015 articles, which were imported into Endnote X4 software. The visualized domain knowledge-mapping was successfully built, and it directly reflected the structure of knowledge-mapping of the subject. And key clusters were formed, in which the "therapy", "method and instrument" and "echocardiography" clusters had been developed well. Conclusions The "therapy" cluster stands in the center of the subject domain knowledge-mapping and is well developed with several clusters following. And the study of the "method and instrument" cluster makes a great contribution to the progress of the subject. The studies of echocardiography and pulmonary artery hypertension play an important role in the structure of the knowledge-mapping.
