Research Article: Partner valves: role of a prospective device selection strategy using ACURATE and SAPIEN 3 as complementary devices in transcatheter aortic valve implantation
Abstract:
Transcatheter aortic valve implantation (TAVI) outcomes using balloon-expandable valves (BEV) and self-expanding valves (SEV) differ owing to device-specific technical features and anatomical factors.
This study aimed to evaluate prospective TAVI device selection based on anatomic features to optimise outcomes compared with published randomised data using two newer-generation devices.
A total of 607 consecutive patients with severe aortic stenosis treated at a single centre from 2020 to 2023 underwent TAVI using a prospective device selection strategy. Heavy and/or asymmetric valve calcification and bicuspid anatomy were preferentially treated with SAPIEN 3/SAPIEN 3 ULTRA BEV, whereas small annulus dimensions and less calcified valves were preferentially treated with ACURATE neo/ACURATE neo2 SEV. In-hospital Valve Academic Research Consortium-3 endpoints and 1-year mortality were evaluated.
ACURATE was used in 182 (30%) patients and SAPIEN 3 in 425 (70%) patients. The proportion of women was higher in the ACURATE group (65% vs. 31%, p <?0.001), and patients were older (84 vs. 80?years, p <?0.001). Technical success (97% vs. 97%, p >?0.99) and new permanent pacemaker implantation during index hospitalisation (10% vs. 10%, p >?0.99) did not differ between the ACURATE and SAPIEN 3 groups. Intended performance was higher in the ACURATE group than in the SAPIEN 3 group (98% vs. 91%, p =?0.005), with aortic regurgitation ?moderate (2% vs. <1%, p =?0.32), and mean transvalvular gradient ?20?mmHg (<1% vs. 4%, p =?0.043). The estimated mortality at 1?year was 14% versus 12% (log-rank p =?0.60) in the ACURATE and SAPIEN 3 groups, respectively.
A prospective device selection strategy using two complementary TAVI valves resulted in comparable outcomes between the SEV and BEV devices. In-hospital intended performance was higher in the ACURATE group. Despite baseline group differences, there was no difference in 1-year mortality.
