The procedural workflow consisted of VOMEI first, followed by left PVI, MI line ablation, roof line ablation, and finally right PVI. At the end of the procedure, both the roof line and the MI line were reassessed after a 15\u2010min waiting period. All procedures were performed using the Farapulse system.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Eighty\u2010seven patients undergoing a PVI\u2010LP plus VOMEI approach as first\u2010line therapy were initially included. Marshall vein cannulation or infusion failure occurred in 9\/87 patients (10.3%). Thus, 78 patients (89.7%) successfully underwent PFA with the PVI\u2010LP plus VOMEI approach and were included in the final analysis.

The rate of 15\u2010min MI reconnection despite VOMEI decreased from 15\/39 (38.5%) in the mitral flower group to 6\/39 (15.4%) in the basket\u2009+\u2009flower\u2009+\u2009Faraview group, corresponding to an absolute risk reduction of 23.1% (95% CI: 4.1%\u201342.1%), a relative risk of 0.40 (95% CI: 0.17\u20130.92), and an unadjusted OR of 0.29 (95% CI: 0.10\u20130.86). Additional applications were delivered whenever MI conduction recovered, until durable bidirectional block was re\u2010established. At the end of the procedure, the mean total number of PFA applications was 60.3\u2009\u00b1\u20099.3: 34.4\u2009\u00b1\u20093.5 for PVI, 8.7\u2009\u00b1\u20092.9 for the roof line, and 17.1\u2009\u00b1\u20096.4 for the mitral line. Acute complications included one nitrate\u2010reversible coronary spasm during the early phase and one acute pericardial tamponade requiring pericardiocentesis. At mid\u2010term follow\u2010up (11\u2009\u00b1\u20093 months), freedom from any atrial arrhythmia after the blanking period was 80.7%. Recurrences included PeAF in six patients, pAF in four, left atrial flutter in four, and right atrial flutter in one.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This real\u2010world prospective cohort study shows that de novo PFA using the PVI\u2010LP plus VOMEI approach is feasible and safe, with a notably short procedural duration.
