This observational study aimed to assess the role of individual anatomical characteristics to predict long-term freedom from arrhythmia recurrence after CB-guided PVI for paroxysmal AF (PAF).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>Three hundred fifty three consecutive patients (58 \u00b1 11 years, 56% males), undergoing PVI between 2012 and 2018 were analysed. Individual pulmonary vein (PV) anatomy was assessed using preprocedural cardiac magnetic resonance imaging (MRI). For each PV, the cross-sectional area (CSA) was calculated. The impact of PV characteristics and CSA on long-term AF-free survival was evaluated.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Acute PVI was achieved in all patients. Two hundred twenty-three patients (63%) had a normal PV anatomy (2 left- and 2 right-sided PV). Variant PV anatomy was present in 130 patients (37%). During the observation period of 48 months, AF-recurrence was documented in 167 patients (47 %). Patients with AF-recurrence presented with significantly enlarged right-sided PVs and left superior PVs (LSPVs) (<jats:italic>p<\/jats:italic> &lt; 0.001). The presence of left common PVs (LCPVs) (<jats:italic>n<\/jats:italic> = 75, Log-rank <jats:italic>p<\/jats:italic> &lt; 0.001) as well as right variant PVs (<jats:italic>n<\/jats:italic> = 35, Log rank <jats:italic>p<\/jats:italic> &lt; 0.001) was associated with a significantly impaired long-term AF-free survival rate as compared to patients with normal PV characteristics.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Variant PV anatomy is a good predictor for AF-recurrence.
