Acute PVI was achieved in 96.2% of cases. Adjunctive PWI was performed in 25.6% of patients, and additional extra\u2010PV lesion sets were performed in 12 patients. Mean procedure, left atrial dwelling, and fluoroscopy times were 65.6\u2009\u00b1\u200916.4, 45.4\u2009\u00b1\u200915.4, and 12.7\u2009\u00b1\u20097.3\u2009min, respectively, with no significant differences between PVI\u2010only and PVI\u2009+\u2009PWI procedures. Two periprocedural complications occurred (1.5%; femoral arterial pseudoaneurysm, pericarditis). Exploratory biomarker analyses showed no evident haemolysis\u2010related renal safety signal. Among 82 patients with \u2265\u20096 months of follow\u2010up, late clinically documented atrial arrhythmia recurrence occurred in 14.6%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In this real\u2010world experience, the balloon\u2010in\u2010basket PFA system showed high acute efficacy, low complication rates, and efficient workflow.
