The National Heart, Lung and Blood Institute (NHLBI) has consistently recognized and supported efforts to advance population, clinical, and basic science research in atrial fibrillation (AF). In 2008, the NHLBI convened an expert panel to identify gaps and to recommend research strategies focused on improving AF prevention. To engage the scientific community in an effort to identify contemporary research priorities and opportunities in AF, the NHLBI recently commissioned a series of webinar-based workshops.
The inaugural webinar in the NHLBI Virtual Workshop Series on Atrial Fibrillation (AF) focused on five topic areas in AF catheter ablation: 1) emerging technologies, 2) how cardiac structure and function influence the success of AF ablation, 3) subgroups of AF patients who may benefit more and less from ablation, 4) platforms to advance clinical research, and 5) whether a sham ablation randomized trial could be conducted in the US. Internationally recognized experts discussed current state of the art and provided recommendations to advance research to optimize the use of and outcomes following AF catheter ablation. The webinar attendees included selected participants including patient advocates who enriched discussion.
Supplemental materials for the preparation and publication of the webinar will be provided when available.
