Catheter ablation was performed as radiofrequency (RF) ablation using 3D mapping, robotic RF ablation, or by using balloon devices. Decent anatomical changes were observed in patients with lobectomy while cardiac rotation and mediastinal shifting was dominant in patients with pneumectomy. Visualization of all PVs including PV stumps by PV angiography was possible in 10 of 19 patients (52.6%). PV spikes were observed in all identified PV remnants. In nine patients (47.4%), at least one PV remnant could not be identified and electrical isolation was not performed. During 24 months follow\u2010up, patients with incomplete PVI had a significantly shorter arrhythmia\u2010free survival than patients with complete PVI (76.2% [95% Confidence interval (CI) 47.2\u2010100.0%] vs 40.0% [95% CI 5.6\u201074.1%], <jats:italic>P<\/jats:italic>\u00a0=\u00a0.043).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In patients with AF and previous lobectomy or pneumectomy, identification and isolation of all PVs are challenging but crucial for ablation success.
