Abstract：
Transcatheter aortic valve implantation (TAVI) was originally devised as a treatment for patients with aortic stenosis (AS). It has since emerged as a beneficial alternative to surgical aortic valve replacement (SAVR), extending its reach to a broader array of patients. Our objective was to illustrate the developmental trends and focus areas in TAVI research. We sourced a total of 11,480 research papers on TAVI, published between 1994 and 2022, from the Web of Science Core Collection (WoSCC) database. We conducted a bibliometric analysis of these publications, generating cooperation maps, performing co-citation analysis of journals and references, and carrying out a cluster analysis of keywords. Our findings indicate that TAVI research grapples with numerous clinical challenges. We created knowledge maps that highlight contributing countries/institutions, authors, journals with high publication and citation rates, and notable references in this domain. North America and Europe have been at the forefront of research within the TAVI field. The institutions and authors from these regions exert significant influence in this area of study. Beginning in 2009, China has progressively expanded its research on TAVI over the past two decades. We anticipate that future research will increasingly focus on three key areas: implementation scope, lifelong management, outcomes and predicting the risk of TAVI. Research on TAVI is flourishing. Cooperation among different countries and institutions in this field must be strengthened in the future, especially for developing counties.
摘要：
经导管主动脉瓣植入术（TAVI）最初被设计为主动脉瓣狭窄（AS）患者的治疗方法。此后，它已成为外科主动脉瓣置换术（SAVR）的有益替代方案，将其延伸到更广泛的患者。我们的目的是说明TAVI研究的发展趋势和重点领域。我们共采购了11,480篇关于TAVI的研究论文，发表于1994年至2022年之间，来自WebofScience核心合集(WoSCC)数据库。我们对这些出版物进行了文献计量分析，生成合作地图，对期刊和参考文献进行共引分析，并对关键词进行聚类分析。我们的发现表明，TAVI研究面临着许多临床挑战。我们创建了知识地图，突出了作出贡献的国家/机构，作者,具有高出版和引用率的期刊，以及该领域中值得注意的参考文献。北美和欧洲一直处于TAVI领域研究的前沿。来自这些地区的机构和作者在这一研究领域发挥着重大影响。从2009年开始，中国在过去的二十年中逐步扩大了对TAVI的研究。我们预计未来的研究将越来越集中在三个关键领域：实施范围，终身管理,结果和预测TAVI的风险。对TAVI的研究正在蓬勃发展。今后必须加强不同国家和机构在这一领域的合作,特别是发展中国家。
