Small valve sizes of Evolut R, including 23 and 26, had higher echocardiographic mean gradient or peak gradient at the time of discharge compared with larger valves, including sizes 29 and 34 (11.1\u2009mm Hg and 11.2\u2009mm Hg vs. 10.2\u2009mm Hg, 9.1\u2009mm Hg) and 1-year follow-up (11.0\u2009mm Hg, 11.0\u2009mm Hg vs. 9.9\u2009mm Hg, 8.4\u2009mm Hg; all <jats:italic toggle=\"yes\">P<\/jats:italic>-values = 0.001).
