Research on the author collaboration network and institutional influence in the transcatheter aortic valve replacement field based on CiteSpace: analysis of the top one hundred highly cited articles.

BACKGROUND

Transcatheter aortic valve replacement (TAVR) has revolutionised the management of severe aortic stenosis, expanding its applications from high-risk to intermediate- and low-risk patients. Understanding the key contributors, collaborative networks and thematic evolutions in TAVR research can inform future investigations.

METHODS

This bibliometric study screened the Web of Science Core Collection for the top 100 highly cited TAVR-related publications between 2010 and 2025. We utilised CiteSpace (version 6.2.R1) to analyse author, country and institutional collaborations, along with references, keywords and citation bursts.

RESULTS

The USA emerged as the most influential country, with leading institutions including the Cleveland Clinic Foundation and Columbia University. Authors such as Martin B. Leon, Rebecca Hahn and Raj R. Makkar held central collaborative roles. Reference co-citation and keyword analyses showed an early emphasis on procedural feasibility and comparisons with surgical aortic valve replacement, followed by a shift toward clinical outcomes, complications (e.g. permanent pacemaker implantation, infective endocarditis) and long-term management. Landmark trials and guidelines (e.g. PARTNER, 2014 American Heart Association/American College of Cardiology Valvular Heart Disease Guideline) exhibited significant citation bursts, underscoring their foundational impact.

CONCLUSIONS

Research on TAVR has evolved in tandem with technological advances and the expansion of clinical indications. Sustained international collaboration and continued study of long-term outcomes, device durability and complication mitigation will be pivotal for optimising TAVR’s therapeutic impact.
