Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients aged 65 and older with severe aortic stenosis and an ascending aortic diameter between 45mm and 54mm.

Probably not a fit

Patients with pure aortic regurgitation or those who have previously undergone aortic valve replacement will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effectiveness of self-expandable versus balloon-expandable valves in patients with ascending aortic dilation undergoing transcatheter aortic valve replacement. Ascending aortic dilation is often seen in patients with aortic stenosis, particularly those with a bicuspid aortic valve. The trial is a multicenter, prospective randomized controlled design, focusing on patients with a maximum ascending aortic diameter of 45mm to 54mm. The goal is to clarify the impact of valve type on patient outcomes in this specific population.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options for patients with aortic stenosis and ascending aortic dilation.

How similar studies have gone: While there have been studies on valve types in aortic procedures, this specific comparison in the context of ascending aortic dilation is novel.

  • Assessing changes in aortic diameter after valve replacement

    This study looks at how the size of the aorta changes after patients have a heart valve replacement to see if it gets bigger or stays the same, especially for those who already had a larger aorta.
