This study aimed to compare outcomes of transcatheter aortic valve replacement between bicuspid and tricuspid aortic valve morphologies in patients with mixed aortic valve disease.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p xml:lang=\"en\">We retrospectively analyzed 282 patients with mixed aortic valve disease who underwent transcatheter aortic valve replacement between January 2019 and June 2024, including 82 with bicuspid aortic valve and 200 with tricuspid aortic valve. Propensity score matching at a 1:1 ratio yielded 82 well\u2010balanced pairs. The primary end point was all\u2010cause death, and secondary end points included technical success, paravalvular leak, clinical adverse events, hemodynamic performance, and left ventricular reverse remodeling.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">\n                      Both groups achieved high technical success rates (97.6% versus 93.9%;\n                      <jats:italic toggle=\"no\">P<\/jats:italic>\n                      =0.443) with comparable procedural outcomes.
