Brief Summary

Title: The ULTRA-EVOLUT Randomized Control Trial: A Head-to-Head Comparison of Latest-Generation Transcatheter Aortic Valves Brief Summary: The goal of this clinical trial is to compare the latest-generation balloon-expandable (SAPIEN 3 Ultra Resilia) versus self-expanding (Evolut FX) transcatheter aortic valves in patients with severe, symptomatic aortic stenosis who are undergoing transcatheter aortic valve implantation (TAVI). The main questions it aims to answer are: Does device success rate (defined by VARC-3 criteria) at 30 days differ between the SAPIEN 3 Ultra Resilia and the Evolut FX valves? Do hemodynamic performance (mean gradient, effective orifice area) and incidence of moderate/severe paravalvular leak differ between the two valve types at 30 days and 1 year? Researchers will compare patients randomized to receive the SAPIEN 3 Ultra Resilia valve versus patients randomized to receive the Evolut FX valve to see if there are differences in device success, safety outcomes, and valve performance. Participants will: Undergo standard pre-procedural clinical, echocardiographic, and CT assessment Be randomly assigned to receive either the SAPIEN 3 Ultra Resilia or Evolut FX valve during their clinically indicated TAVI procedure Receive post-procedure follow-up assessments including echocardiography and clinical evaluation at 24 hours, 30 days, 6 months, and 1 year

Outcome Measures

Primary Outcomes (1)

  • Device Success Rate at 30 Days

    Composite endpoint defined according to Valve Academic Research Consortium-3 (VARC-3) criteria, including: absence of procedural mortality, correct positioning of a single prosthetic heart valve into the proper anatomical location, absence of moderate or severe prosthetic valve regurgitation (paravalvular or central), and acceptable hemodynamic performance (mean aortic valve gradient \<20 mmHg or peak velocity \<3 m/s)

    30 days post-procedure

Secondary Outcomes (1)

  • Mean Aortic Valve Gradient

    3 months post-procedure

Study Arms (2)

SAPIEN 3 Ultra Resilia

ACTIVE COMPARATOR

Balloon-expandable transcatheter aortic valve with anti-calcification tissue treatment.

Device: SAPIEN 3 Ultra Resilia

Evolut FX

ACTIVE COMPARATOR

Self-expanding transcatheter aortic valve with enhanced radial strength and conformability.

Device: Evolut FX

Interventions

Balloon-expandable transcatheter aortic valve featuring anti-calcification tissue treatment. Delivered via transcatheter approach (typically transfemoral) under fluoroscopic guidance. Valve sizes available include 20 mm, 23 mm, 26 mm, and 29 mm.

SAPIEN 3 Ultra Resilia
Evolut FXDEVICE

Self-expanding transcatheter aortic valve with enhanced radial strength and conformability. Features a recapturable and repositionable delivery system. Delivered via transcatheter approach (typically transfemoral). Valve sizes available include 23 mm, 26 mm, 29 mm, and 34 mm.

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:
