TAVI for Heart Valve Disease
(BASELINE Trial)
Trial Summary
What is the purpose of this trial?
Transcatheter aortic valve implantation (TAVI) serves a growing spectrum of patients with symptomatic severe aortic stenosis (AS). Approximately 80% of surgical aortic valve replacements is performed using a bioprosthesis1. Durability of surgical bioprostheses varies based on the patient's age at the moment of implantation, type and size etc2. TAVI has become the preferred treatment for degenerated aortic bioprostheses in elderly patients3. The median time since index surgical aortic valve replacement (SAVR) and for bioprosthetic valve degeneration is typically 8 - 10 years4-6. TAVI in this setting has proven to have equally favorable results as in native aortic valves7. Balloon expandable8 and self-expanding9 transcatheter heart valves (THV) can be used in a degenerated bioprosthesis and each have specific assets and limitations. TAVI in a failed bioprosthesis can cause coronary obstruction, THV migration, paravalvular leakage and prosthesis patient mismatch. The SAPIEN-3 / Ultra and EVOLUT R/Pro are the 2 most commonly used THV platforms in contemporary clinical practice including treatment of failing surgical aortic bioprostheses. Objective: To compare TAVI with EVOLUT R/Pro vs. SAPIEN-3 / Ultra in terms of device success. Study design: International multi-center randomized study with 1:1 randomization to TAVI with SAPIEN-3 / Ultra or Evolut R/Pro. Study population: 440 patients with a failing surgical aortic bioprosthesis (aortic stenosis with or without aortic regurgitation) and selected for transfemoral TAVI by heart-team consensus. Investigational intervention: Transfemoral TAVI with SAPIEN-3 / Ultra or Evolut R/PRO Main study parameters/endpoints: 1. Primary endpoint is device success at 30 days Defined by * Absence of procedural mortality AND * Correct positioning of a single prosthetic heart valve into the proper anatomical location AND * Intended performance of the prosthetic heart valve (no severe prosthesis- patient mismatch and mean aortic valve gradient \< 20 mmHg or peak velocity \< 3 m/s, AND no moderate or severe prosthetic valve regurgitation). Severe prosthesis patient mismatch is defined by effective orifice area (EOAi) ≤0.65 cm2/m2 2. Safety endpoint at 1 year defined by the composite of all-cause death, disabling stroke, rehospitalization for heart failure or valve related problems.
Do I need to stop my current medications for the TAVI trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What data supports the effectiveness of the treatment Edwards Sapien S3/Ultra bioprosthesis and Evolut R/PRO bioprosthesis for heart valve disease?
Research shows that both the Edwards SAPIEN S3 and Medtronic Evolut R devices have high success rates for transcatheter aortic valve implantation (TAVI), with device success rates of over 90% and low 30-day mortality rates. Long-term outcomes are similar for both devices, with survival mainly influenced by other health conditions.12345
Is TAVI generally safe for humans?
How does the TAVI treatment with Edwards Sapien S3/Ultra and Evolut R/PRO differ from other treatments for heart valve disease?
The TAVI treatment using Edwards Sapien S3/Ultra and Evolut R/PRO is unique because it involves a minimally invasive procedure to replace the heart valve without open-heart surgery, making it suitable for patients at high surgical risk. These newer-generation valves are designed to reduce complications like paravalvular leaks and vascular injuries, offering improved safety and outcomes compared to older valve systems.15689
