This session highlights 5 selected abstracts on disparities in cardiac care, focusing on gender, geography, and social determinants of health. Topics include trends in device utilization, diagnosis-to-ablation times, and sex-based differences in atrial fibrillation outcomes, with insights from real-world and nationwide data. Presentations will be judged and recognized for their work.

• Describe sex differences and disparities in heart rhythm care.
• Summarize ablation targets and outcomes by sex.
• Review the association between SDOH and time from diagnosis to ablation of AF.
