Among female patients , procedural mortality trended lower with TAVR versus SAVR ( 6.8 % vs. 13.1 % ; p = 0.07 ) and was maintained throughout follow-up ( hazard ratio [ HR ] : 0.67 ; 95 % confidence interval [ CI ] : 0.44 to 1.00 ; p = 0.049 ) , driven by the transfemoral arm ( HR : 0.55 ; 95 % CI : 0.32 to 0.93 ; p = 0.02 ) .
