While radiofrequency wire (RFW)\u2010based transseptal puncture (TSP) offers advantages over mechanical needle (MN) techniques, adoption in Europe has been limited due to concerns about the need for costly adjunctive imaging. This study evaluated the feasibility of using RFW\u2010based TSP within fluoroscopy\u2010only pulsed field ablation (PFA) procedures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A retrospective, single\u2010center chart review of consecutive PFA cases was conducted. TSP was performed using either an MN or RFW, with MN serving as a feasibility benchmark. All procedures used the pentaspline PFA system under standard\u2010of\u2010care protocols, with fluoroscopy as the primary imaging modality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 617 PFA procedures were analyzed (435 RFW, 182 MN). Baseline characteristics were similar. LA access was successful in all RFW cases, with no significant difference in complication rates. Notably, no RFW cases required adjunctive echocardiography, compared to three in the MN group (0% vs. 1.6%,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.01). Procedural times and fluoroscopy exposure were comparable. In patients with prior TSP, RFW enabled significantly faster and more consistent access than MN (8.1\u2009\u00b1\u20093.9\u2009min vs. 11.1\u2009\u00b1\u20095.8\u2009min,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.01).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Purpose\u2010built RFW systems demonstrated comparable safety and efficacy to MN\u2010based devices in fluoroscopy\u2010only PFA workflows, with added efficiency and predictability in complex anatomies.
