The predicted valve\u2010to\u2010sinotubular junction (VTSTJ) length and calcium volume of each coronary cusp were measured on pre\u2010procedural CT. The observed VTSTJ length was assessed on post\u2010procedural CT. High SS risk was defined as VTSTJ\u2009&lt;\u20092.0\u2009mm in either the right or left coronary cusp. Pre\u2010procedural CT classified 78 patients into the high predicted SS (PSS) risk group; 77 (98.7%) showed a high observed SS (OSS) risk on post\u2010procedural CT. Among the 61 patients classified as having low PSS risk, 44 (72.1%) were found to have high OSS risk post\u2010TAVR. In this subgroup, patients with high OSS risk had a significantly higher proportion of non\u2010coronary cusp calcium volume (NCC\u2010CV) compared to those with low OSS risk (median 48.7% [interquartile range (IQR): 42.1\u201355.2] vs. 39.2% [IQR: 33.7\u201345.4];\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.004).
