Self\u2010expanding valves (SEVs) have evolved delivery catheter designs, from a double spine shaft in Evolut PRO+ (PRO\u2009+\u2009) to single spine in Evolut FX (FX) and non\u2010spine in Navitor, to improve access deliverability.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Aims<\/jats:title>\n                    <jats:p>To investigate the influence of different spine structures on valve implantation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Retrospectively, we investigated 95 severe aortic stenosis patients who underwent transfemoral TAVR using SEVs (PRO\u2009+\u2009: 41, FX: 21, and Navitor: 33 patients) from January 2021 to July 2023. The implantation depth difference (IDD) between Left Coronary Cusp (LCC) and Non\u2010Coronary Cusp (NCC) was measured angiographically at the point of no recapture, defined as subtracting NCC implantation depth from LCC. Positive IDD indicates deeper LCC than NCC, also shown as \u201cvertical axis.\u201d Whereas negative IDD indicates shallower LCC than NCC, demonstrated as \u201chorizontal axis.\u201d<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      IDD at the point of no recapture showed significant difference among three groups (PRO\u2009+\u2009: 2.42 [0.81\u20133.42], FX: 1.01 [0.29\u20131.77], Navitor: \u20132.16[\u20132.74\u2013 (\u20131.14)] mm,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001, PRO\u2009+\u2009&gt;\u2009FX\/Navitor, FX &gt; Navitor).
