Coronary overlap (CO) was assessed by measuring the angle between the neo\u2010commissure and coronary ostium. Coronary geometry was evaluated by the vertical distance from the coronary ostium to top of the outer skirt and the horizontal distance from the ostium to the transcatheter heart valve (THV) frame.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The SA\u2010SEV was associated with significantly lower rates of severe CO than the IA\u2010SEV in both the left (LCA) (10% vs. 42%) and right coronary arteries (RCA) (12% vs. 34%). The vertical distance from the coronary ostium to the outer skirt was shorter in SA\u2010SEV than in IA\u2010SEV for both arteries (LCA: 3.3\u2009mm vs. 8.0\u2009mm; RCA: 4.4\u2009mm vs. 9.0\u2009mm). Conversely, SA\u2010SEV demonstrated a wider horizontal distance between the coronary ostium and THV frame than IA\u2010SEV (LCA: 4.8\u2009mm vs. 3.8\u2009mm; RCA: 5.4\u2009mm vs. 4.4\u2009mm).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>CO and ostial geometry relative to the THV frame differed significantly between the two SEV platforms.
