Valve Performance of the SAPIEN 3 Ultra RESILIA Valve: A Prospective Registry With Central Echocardiography Analysis.

Prospective observational registry including patients with severe aortic stenosis undergoing TAVR with the SAPIEN 3 Ultra RESILIA valve. All patients who will survive the procedure will undergo a clinical and echocardiographic follow-up at 1-3 months (± 15 days), at 1-year (±30 days), 3-5 year (±30 days), 6-8 year (±30 days) and 9-10 year (±30 days) after valve implantation. Transthoracic echocardiography (TTE) exams (baseline, 1-3-month, 1 year, 3-5 years, 6-8 years, and 9-10 years post-procedure) will be evaluated in a Centralized Echocardiographic Core Lab at the Quebec Heart and Lung Institute. The measurements obtained in the Core Lab regarding transvalvular gradient, EOA, PPM and PVL at 1-3 months will determine the primary outcome of the study.

Inclusion criteria

• Inclusion criteria - Patients with severe aortic stenosis undergoing transarterial TAVR with the SAPIEN 3 Ultra RESILIA valve.
