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
Eligibility criteria
Qualifiers
Severe aortic stenosis defined as aortic valve area (AVA) ≤1.0 cm², mean transvalvular gradient ≥40 mmHg, or peak transvalvular velocity ≥4.0 m/s
Symptomatic with New York Heart Association (NYHA) functional class II, III, or IV
Heart team consensus that transcatheter aortic valve implantation (TAVI) is the appropriate treatment strategy
Anatomically suitable for both valve types (SAPIEN 3 Ultra Resilia and Evolut FX) as determined by pre-procedural computed tomography (CT) imaging
Disqualifiers
Bicuspid aortic valve morphology
Severe mitral regurgitation or severe tricuspid regurgitation requiring intervention
Prior surgical or transcatheter aortic valve replacement
Active infective endocarditis
