Aortic Valve Stenosis, Transcatheter Aortic Valve Replacement
Conditions
Brief summary
The issue of valve durability has become one of the most important aspects in the TAVR field in recent years since transcatheter aortic valve replacement has been progressively applied to younger patients with a low co-morbidity burden. The SAPIEN 3 Ultra RESILIA valve represents the last generation of the SAPIEN valve system and includes several important iterations (newer leaflet calcium-blocking technology targeting calcium-attracting free aldehydes, dry tissue storage, newer skirt textile design) that should translate into a favorable impact on valve durability at mid- to long- term follow-up
Detailed description
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.
