Real-world data on patient selection, outcomes, and complications with PVI or PVI plus (\u22651 additional line or CFAE\/ganglionated plexi ablation) are limited.

They were categorized by ablation strategy (PVI or PVI plus), and baseline characteristics and trends were assessed. AF recurrence was analysed using cumulative incidence at one and five years, and across procedural years. Major adverse cardiovascular events (MACE) and procedure-related complications were also examined. Among 4144 peAF patients, 3.417 received PVI and 727 PVI plus. Baseline characteristics were similar, except the PVI plus group had longer diagnosis-to-ablation-time (mean 5.67 years vs. 3.9 years, P &amp;lt; 0.001) and more severe atrial enlargement (14.8% vs. 9.8%, P &amp;lt; 0.001). AF recurrence was higher with PVI plus at one- and five-years (54% vs. 46%, 77% vs. 68%). Recurrence rates declined over time (2010\u20132013 vs. 2018\u20132020). PVI plus use decreased from 58% to 15%. MACE and complication rates were low and similar.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>PVI plus was used less frequently over time and was associated with longer diagnosis-to-ablation times and larger left atria.
