Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients who have undergone surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI) for severe aortic stenosis.

Probably not a fit

Patients with significant aortic regurgitation, recent revascularization, or other specific cardiac conditions may not benefit from this study.

What this trial studies

This study aims to evaluate the hemodynamic performance of various aortic valve prostheses through both in vitro and in vivo methods. It involves collecting data from standard clinical procedures, including echocardiograms and 4D Flow cardiac MRI, to assess the performance of these valves after surgical implantation. The study will last for 24 months, with patient involvement concluding 1-3 months post-intervention. The focus is on patients with severe aortic valve stenosis, particularly those with small aortic annuli, to understand how different prostheses perform under simulated and real conditions.

Why it matters

Potential benefit: If successful, this study could lead to improved outcomes for patients undergoing valve replacement for aortic stenosis.

How similar studies have gone: Other studies have explored similar methodologies in valve performance assessment, indicating potential for success in this area.
