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.
