Methods: We analyzed the first 944 patients included in the Spanish Prospective Multi-center Observation Post-market Registry to compare characteristics and outcomes of patients undergoing CBA for PeAF versus PaAF. Results: A total of 944 patients (57.8 ± 10.4 years; 70.1% male) with AF (27.9% persistent) were prospectively included from 25 centers. PeAF patients were more likely to have structural heart disease (67.7 vs. 11.4%; p SN 2077-0383 YR 2022 FD 2022-02-22 LK http://hdl.handle.net/10668/21243 UL http://hdl.handle.net/10668/21243 LA en DS RISalud RD Apr 20, 2025
