Global trends and research hotspots in transcatheter valve replacement for aortic regurgitation: a bibliometric and visualized analysis

This study is the first comprehensive bibliometric analysis of TAVR for AR, offering insights into health-oriented research trends. Despite advancements in clinical studies, minimally invasive surgical techniques, and bioengineering, prioritizing translational research to address patient health outcomes remains critical. Bridging innovation and clinical practice is vital to optimize therapeutic efficacy, improve quality of life, and reduce AR's global health burden. Future research should integrate multidisciplinary approaches to enhance TAVR's safety, accessibility, and long-term health benefits for diverse populations.
