Interest in pulsed field ablation for atrial fibrillation is accelerating; leaves open the need for randomized trials before clinical adoption.
Background Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia worldwide, posing significant health burdens. Pulsed field ablation (PFA) is an emerging non-thermal technique that is gaining traction due to the ability to selectively target myocardial cells and minimize damage to surrounding tissues. We conducted a comprehensive bibliometric analysis of PFA use in AF treatment to map research trends, collaborations, and future directions. Methods We extracted data from the Web of Science Core Collection on September 6, 2024, using search terms related to PFA and AF. Publication trends, citation trajectories, collaborative networks, and keyword co-occurrences were analyzed utilizing tools such as Bibliometrix R, VOSviewer, and CiteSpace. Results In total, 217 publications were retrieved. The number of publications increased rapidly from 2019 to 2024, with a notable surge occurring after 2022. Contributions from the United States, Germany, and China accounted for more than 60% of all publications. The institution with the largest output was The Icahn School of Medicine at Mount Sinai. The most productive journals were Europace and the Journal of Interventional Cardiac Electrophysiology . Prolific authors were identified, underscoring significant international collaborations. The most cited publications highlighted the efficacy and safety of PFA. Keywords with strong recent citation bursts included “tissue”, “cardiomyopathy”, and “closed chest ablation”. Conclusion PFA is becoming established as a viable alternative for AF ablation, showing promising safety and efficacy. This bibliometric analysis confirmed the growing scientific interest and collaborative efforts in this field, suggesting that robust future developments will occur.
