Patients were randomized (1:1) to either a 3D\u2010EAM\u2010visualized steerable sheath (Vizigo) or a conventional non\u2010visualized steerable sheath (Agilis) group. Key endpoints included procedure and fluoroscopy times, pulmonary vein isolation (PVI) effectiveness, and 12\u2010month AF recurrence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Acute PVI was successfully achieved in all patients.

First\u2010pass PVI success in left\u2010sided veins was significantly higher in the Vizigo group than that in the Agilis group (84% vs. 64%,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.023).

Furthermore, the improved left\u2010sided first\u2010pass PVI success observed with the Vizigo sheath may have implications for procedural efficacy, although its effect on long\u2010term outcomes warrants further investigation with larger cohorts.<\/jats:p>\n
