HotBalloon\u2010based pulmonary vein isolation (PVI) has demonstrated encouraging clinical results in the treatment of paroxysmal atrial fibrillation (PAF), however, the acute efficacy and clinical outcomes of the HotBalloon\u2010based PVI have never been fully investigated in patients with a left common pulmonary vein (LCPV).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and Results<\/jats:title><jats:p>One hundred fifty\u2010three PAF patients underwent HotBalloon\u2010based PVI. Three\u2010dimensional computed tomography was performed in all patients before the ablation. An LCPV was observed in 40 (26%) patients. For HotBalloon ablation of an LCPV, in patients with an LCPV of superoinferior diameter &lt;34\u2009mm, the left common ostium was preferably isolated if sufficient occlusion could be achieved. In patients with an LCPV diameter \u226534\u2009mm, left superior and inferior branches of the LCPV were targeted individually. The number of HotBalloon applications in patients with LCPV was significantly smaller than without LCPV (7.3\u2009\u00b1\u20092.0 vs 8.1\u2009\u00b1\u20092.1; <jats:italic>P<\/jats:italic>\u2009=\u2009.04). In patients with LCPV diameter &lt;34\u2009mm, 75% of LCPVs successfully achieved full balloon occlusion (50% were isolated by application at the LCPV ostium alone, 25% by application at the LCPV ostium followed by either superior or inferior LCPV branch ablation) and 25% were isolated individually. One year after a single session, the arrhythmia\u2010free rates were similar between patients with and without LCPV (77% vs 74%, log rank,
