Preprocedural computed tomography assessed RSPV anatomical features, including ostial diameters, cross\u2010sectional area, and the RSPV\u2013left atrium (LA) angle, defined as the angle between the RSPV and anterolateral LA wall on axial slices. The overall incidence of PNI did not differ between groups (28\u2010mm: 10%; 31\u2010mm: 15%;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.330). However, persistent PNI, defined as dysfunction beyond the procedure, occurred only in the 28\u2010mm group (5%). Multivariate analysis showed that the RSPV\u2013LA angle independently predicted PNI in both groups (28\u2010mm: odds ratio 3.819, 95% confidence interval 1.825\u20137.926,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001; 31\u2010mm: odds ratio 3.633, 95% confidence interval 1.538\u20138.594,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.003).
