Evolut PRO and SAPIEN ULTRA Performance in Small Aortic Annuli: The OPERA-TAVI Registry.

BACKGROUND: The performance of latest iteration transcatheter aortic valve replacement platforms in patients with small aortic anatomy remains underexplored. OBJECTIVES: The aim of this study was to evaluate effectiveness and performance between the self-expanding (SE) Evolut PRO and PRO+ and the balloon-expandable (BE) SAPIEN ULTRA in patients with small aortic annuli. METHODS: Data from the OPERA-TAVI (Comparative Analysis of Evolut PRO vs. SAPIEN 3 ULTRA Valves for Transfemoral Transcatheter Aortic Valve Implantation) registry were used, with 1:1 propensity score matching. Primary endpoints included 1-year effectiveness composite (all-cause mortality, disabling stroke, or heart failure hospitalization) and 30-day device-related (hemodynamic structural valve dysfunction and nonstructural valve dysfunction) outcomes. RESULTS: Among 3,516 patients, 251 matched pairs with aortic annular area <430 mm2 were assessed. The 1-year primary effectiveness outcome did not differ significantly between cohorts (SE 10.8% vs BE 11.2%; P = 0.91). The 30-day device-oriented composite outcome was more favorable in the Evolut PRO group (SE 4.8% vs BE 10.4%; P = 0.027). Notably, SE valve recipients showed higher rates of disabling stroke (SE 4.0% vs BE 0.0%; P < 0.01) and paravalvular leaks (mild or greater: SE 48.5% vs BE 18.6% [P < 0.001]; moderate: SE 4.5% vs BE 1.2% [P = 0.070]). The BE group had higher rates of prosthesis-patient mismatch (moderate or greater: SE 16.0% vs BE 47.1% [P < 0.001]; severe: SE 1.3% vs BE 5.7% [P = 0.197]) and more patients with residual mean gradients >20 mm Hg (SE 1.0% vs BE 13.5%; P < 0.001). CONCLUSIONS: In patients with small aortic annuli, transcatheter aortic valve replacement with latest iteration devices is safe. SE platforms are associated with more favorable device performance in terms of hemodynamic structural and nonstructural dysfunction. Randomized data are needed to validate these findings and guide informed device selection.

Sex-Related Outcomes of Transcatheter Aortic Valve Implantation With Self-Expanding or Balloon-Expandable Valves: Insights from the OPERA-TAVI Registry.

Evidence regarding gender-related differences in response to transcatheter aortic valve implantation according to the valve type is lacking. This study aimed to evaluate the impact of gender on the treatment effect of Evolut PRO/PRO+ (PRO) or SAPIEN 3 Ultra (ULTRA) devices on clinical outcomes. The 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 who underwent the latest-iteration PRO or ULTRA implantation. Overall, 1,174 of 1,897 patients were matched based on valve type and compared according to gender, whereas 470 men and 630 women were matched and compared according to valve type. The 30-day and 1-year outcomes were evaluated. In the PRO and ULTRA groups, men had a higher co-morbidity burden, whereas women had smaller aortic root. The 30-day (device success [DS], early safety outcome, permanent pacemaker implantation, patient-prosthesis mismatch, paravalvular regurgitation, bleedings, vascular complications, and all-cause death) and 1-year outcomes (all-cause death, stroke, and heart failure hospitalization) did not differ according to gender in both valve groups. However, the male gender decreased the likelihood of 30-day DS with ULTRA versus PRO (p for interaction = 0.047). A higher risk of 30-day permanent pacemaker implantation and 1-year stroke and a lower risk of patient-prosthesis mismatch was observed in PRO versus ULTRA, regardless of gender. In conclusion, gender did not modify the treatment effect of PRO versus ULTRA on clinical outcomes, except for 30-day DS, which was decreased in men (vs women) who received ULTRA (vs PRO).

One-year clinical outcomes of transcatheter aortic valve implantation with the latest iteration of self-expanding or balloonexpandable devices: insights from the OPERA-TAVI registry.

BACKGROUND: Midterm comparative analyses of the latest iterations of the most used Evolut and SAPIEN platforms for transcatheter aortic valve implantation (TAVI) are lacking. AIMS: We aimed to compare 1-year clinical outcomes of TAVI patients receiving Evolut PRO/PRO+ (PRO) or SAPIEN 3 Ultra (ULTRA) devices in current real-world practice. METHODS: Among patients enrolled in the OPERA-TAVI registry, patients with complete 1-year follow-up were considered for the purpose of this analysis. One-to-one propensity score matching was used to compare TAVI patients receiving PRO or ULTRA devices. The primary endpoint was a composite of 1-year all-cause death, disabling stroke and rehospitalisation for heart failure. Five prespecified subgroups of patients were considered according to leaflet and left ventricular outflow tract calcifications, annulus dimensions and angulation, and leaflet morphology. RESULTS: Among a total of 1,897 patients, 587 matched pairs of patients with similar clinical and anatomical characteristics were compared. The primary composite endpoint did not differ between patients receiving PRO or ULTRA devices (Kaplan-Meier [KM] estimates 14.0% vs 11.9%; log-rank p=0.27). Patients receiving PRO devices had higher rates of 1-year disabling stroke (KM estimates 2.6% vs 0.4%; log-rank p=0.001), predominantly occurring within 30 days after TAVI (1.4% vs 0.0%; p=0.004). Outcomes were consistent across all the prespecified subsets of anatomical scenarios (all pinteraction>0.10). CONCLUSIONS: One-year clinical outcomes of patients undergoing transfemoral TAVI and receiving PRO or ULTRA devices in the current clinical practice were similar, but PRO patients had higher rates of disabling stroke. Outcomes did not differ across the different anatomical subsets of the aortic root.

Transcatheter Aortic Valve Replacement With the Latest-Iteration Self-Expanding or Balloon-Expandable Valves: The Multicenter OPERA-TAVI Registry.

BACKGROUND: The latest iterations of devices for transcatheter aortic valve replacement (TAVR) have brought refinements to further improve patient outcomes. OBJECTIVES: This study sought to compare early outcomes of patients undergoing TAVR with the self-expanding (SE) Evolut PRO/PRO+ (Medtronic, Inc) or balloon-expandable (BE) Sapien 3 ULTRA (Edwards Lifesciences) devices. METHODS: The OPERA-TAVI (Comparative Analysis of Evolut PRO vs Sapien 3 Ultra Valves for Transfemoral Transcatheter Aortic Valve Implantation) registry collected data from 14 high-volume centers worldwide on patients undergoing TAVR with SE or BE devices. After excluding patients who were not eligible for both devices, patients were compared using 1:1 propensity score matching. The primary efficacy and safety outcomes were Valve Academic Research Consortium-3 device success and early safety, respectively. RESULTS: Among 2,241 patients eligible for the present analysis, 683 pairs of patients were matched. The primary efficacy outcome did not differ between patients receiving SE or BE transcatheter aortic valves (SE: 87.4% vs BE: 85.9%; P = 0.47), but the BE device recipients showed a higher rate of the primary safety outcome (SE: 69.1% vs BE: 82.6%; P < 0.01). This finding was driven by the higher rates of permanent pacemaker implantation (SE: 17.9% vs BE: 10.1%; P < 0.01) and disabling stroke (SE: 2.3% vs BE: 0.7%; P = 0.03) in SE device recipients. On post-TAVR echocardiography, the rate of moderate to severe paravalvular regurgitation was similar between groups (SE: 3.2% vs BE: 2.3%; P = 0.41), whereas lower mean transvalvular gradients were observed in the SE cohort (median SE: 7.0 vs BE: 12.0 mm Hg; P < 0.01). CONCLUSIONS: The OPERA-TAVI registry showed that SE and BE devices had comparable Valve Academic Research Consortium-3 device success rates, but the BE device had a higher rate of early safety. The higher permanent pacemaker implantation and disabling stroke rates in SE device recipients drove this composite endpoint.
