Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are patients aged 70 years and older with symptomatic, severe aortic valve stenosis who are deemed unsuitable for surgical aortic valve replacement.
✕Probably not a fit
Patients with unsuitable aortic root anatomy, vascular diseases preventing device access, or those with ongoing infections will not benefit from this study.

What this trial studies
This observational study aims to assess the safety and effectiveness of the VitaFlow™ Transcatheter Aortic Valve System in treating severe aortic stenosis in real-world settings. It is a prospective, single-arm, multi-center registry that will follow patients before and after the procedure, with evaluations at discharge, 30 days, 1 year, and annually up to 5 years. The study includes patients who are not suitable for surgical aortic valve replacement and focuses on gathering data on the valve's performance and patient outcomes.
Why it matters
Potential benefit: If successful, this study could provide a less invasive treatment option for patients with severe aortic stenosis who are not candidates for traditional surgery.
How similar studies have gone: Other studies have shown success with similar transcatheter valve approaches, indicating a promising avenue for treatment.
