Patient Population
We conducted a single-center, retrospective observational study of patients enrolled in a prospectively populated AF ablation database approved by the Johns Hopkins IRB. The study cohort is comprised of patients undergoing first catheter ablation from January 1, 2014, to March 31, 2021. Patient characteristics were systematically recorded, including demographic, clinical, and echocardiographic parameters. We also investigated duration and progression of AF, prescribed medication information, number of electrophysiologist appointments from diagnosis to ablation, AF types, and procedural data.
