Background: The ACURATE neo2 (NEO2) and Evolut PRO/PRO+ (PRO) bioprostheses are new-generation self-expanding valves developed for transcatheter aortic valve replacement (TAVR). Aims: We sought to compare the performance of the ACURATE neo2 and Evolut PRO/PRO+ devices. Methods: The NEOPRO-2 registry retrospectively included patients who underwent TAVR for severe aortic stenosis with either the NEO2 or PRO devices between August 2017 and December 2021 at 20 centres. In-hospital and 30-day Valve Academic Research Consortium (VARC)-3 defined outcomes were evaluated. Propensity score (PS) matching and binary logistic regression were performed to adjust the treatment effect for PS quintiles. A subgroup analysis assessed the impact of aortic valve calcification. Results: A total of 2,175 patients (NEO2: n=763; PRO: n=1,412) were included. The mean age was 82±6.2 years and the mean Society of Thoracic Surgeons score was 4.2%. Periprocedural complications were low, and both groups achieved high rates of technical success (93.1% vs 94.1%; p=0.361) and predischarge intended valve performance (96.0% vs 94.1%; p=0.056), both in the unmatched and matched analysis (452 pairs). Device success at 30 days was comparable (84.3% vs 83.6%; p=0.688), regardless of aortic valve calcification severity (p>0.05 for interaction). A suggestion for higher VARC-3 early safety in the NEO2 group was mainly driven by reduced rates of new permanent pacemaker implantation (7.7% vs 15.6%; p<0.001). Conclusions: This retrospective analysis reports a similar short-term performance of the ACURATE neo2 platform compared with the new-generation Evolut PRO/PRO+ devices. Randomised studies are needed to confirm our exploratory findings., Background: The ACURATE neo2 (NEO2) and Evolut PRO/PRO+ (PRO) bioprostheses are new-generation self-expanding valves developed for transcatheter aortic valve replacement (TAVR).

Background: In recent years, transcatheter aortic valve replacement (TAVR) techniques and technology have continuously improved. Data regarding the impact of these advancements on outcomes in large real-world settings are still limited. The aim of this study was to investigate temporal trends and assess contemporary outcomes after TAVR with Evolut PRO/PRO+ supra-annular self-expanding valves. Methods: This study included patients enrolled in the multicenter NEOPRO (A Multicenter Comparison of Acurate NEO Versus Evolut PRO Transcatheter Heart Valves) and NEOPRO-2 (A Multicenter Comparison of ACURATE NEO2 Versus Evolut PRO/PRO+ Transcatheter Heart Valves 2) registries who underwent transfemoral TAVR with Evolut PRO/PRO+. Procedural dates (August 2017 through November 2021) were stratified in quartiles (Q) and used to investigate temporal trends in TAVR outcomes. Predischarge, 30-day Valve Academic Research Consortium-3 defined, and 1-year outcomes were evaluated. Results: In total, 1616 patients from 28 centers were included. Over time, patients had lower Society of Thoracic Surgeon-Predicted Risk of Mortality score (Q1–4, 4.1% [2.8–6.3%], 3.7% [2.6–5.3%], 3.3% [2.4–4.9%], 2.9% [2.2–4.3%]; P<0.001) and more moderate or heavy valve calcification (Q1–4, 80%, 80%, 82%, 88%; P=0.038). Overall Valve Academic Research Consortium-3 technical success was 94.1%, with 30-day and 1-year all-cause mortality of 2.4% and 10%, respectively. Throughout the study period, procedures were associated with higher rates of 30-day device success (Q1–4, 81.2%, 82.2%, 82.0%, 88.0%; Cochran-Armitage P=0.023) and early safety (Q1–4, 66.8%, 67.5%, 74.0%, 77.6%; Cochran-Armitage P<0.001), with fewer permanent pacemaker implantations (Q1–4: 15.3%, 20.0%, 12.1%, 11.6%; Cochran-Armitage P=0.023) and residual mild or greater paravalvular leaks (Q1–4, 50.4%, 42.1%, 36.5%, 35.8%; Cochran-Armitage P<0.001).
