Evidence regarding sex-related differences in response to transcatheter aortic valve implantation according to the valve type is lacking. This study sought to evaluate the impact of sex on the treatment effect of Evolut-PRO/PRO+ (PRO) or Sapien 3 Ultra (ULTRA) devices on clinical outcomes. Comparative Analysis of Evolut PRO vs Sapien 3 Ultra Valves for Transfemoral Transcatheter Aortic Valve Implantation (OPERA-TAVI) is a multicenter multinational registry including patients undergoing latest-iteration PRO or ULTRA implantation. Overall, 1174 out of 1897 patients were matched based on valve type and compared according to sex, while 470 males and 630 females were matched and compared according to valve type. Thirty-day and 1-year outcomes were evaluated. In both PRO and ULTRA group, males had a higher comorbidity burden, while females had smaller aortic root. Both 30-day (device success [DS], early safety outcome, permanent pacemaker implantation [PPI], patient-prosthesis mismatch [PPM], paravalvular regurgitation [PVR], bleedings, vascular complications, and all-cause death) and 1-year outcomes (all-cause death, stroke and heart failure hospitalization) did not differ according to sex in both valve groups. However, male sex decreased the likelihood of 30-day DS with ULTRA versus PRO (p for interaction 0.047). A higher risk of 30-day PPI and 1-year stroke, and a lower risk of PPM was observed in PRO versus ULTRA, regardless of sex. In conclusion, sex did not modify the treatment effect of PRO versus ULTRA on clinical outcomes, with the exception of 30-day DS that was decreased in males (versus females) receiving ULTRA (versus PRO).
