Comparing Allegra and Sapien valves for valve-in-valve procedure
Part of Heart & circulation clinical trials.
This trial tests two different replacement heart valves (Allegra and Sapien) to see which works better for people who need a new valve placed inside a previously implanted surgical valve. It aims to help patients with a failing biological aortic valve who are already scheduled for this procedure.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have a surgically implanted biological aortic valve that is not working well (narrowed or leaking severely).
- You have symptoms like chest pain, shortness of breath, or dizziness, or your heart's pumping function has worsened due to the valve problem.
- Your heart team has decided that a valve-in-valve procedure is the right option for you.
- You are willing to come back for a heart ultrasound at 30 days and have a phone check at 1 year.

Other trials that look related to this one.
This study follows patients with severe aortic stenosis who get a new heart valve (the SAPIEN 3 Ultra RESILIA) through a less invasive procedure (TAVR). Researchers want to see how well this valve works over time using special heart ultrasound tests.
This study compares regular monitoring (“clinical surveillance”) versus replacing the aortic valve using a minimally invasive procedure called TAVR for people with moderate aortic stenosis. It aims to see which approach better reduces symptoms or heart damage over time.
This trial studies whether a new transcatheter aortic valve (SAPIEN X4) is safe and works well in people whose previously implanted aortic valve is now failing. It may help reduce valve symptoms in higher-surgery-risk patients who are not good candidates for open-heart valve replacement.
This trial tests a new heart valve device (Venus-Vitae) for people with severe aortic stenosis, a condition where the heart valve is too tight. It aims to see if the device works well for patients of all surgical risk levels.
This trial tests a new heart valve replacement (TAVR) system in people with severe, symptomatic aortic stenosis. If you qualify, it may offer a less invasive option compared with open-heart valve surgery, while also helping researchers understand safety and early effectiveness.
This trial compares two ways to check and fine-tune how well a new valve is working after a “valve-in-valve” TAVR procedure. It looks to see whether measurements from ultrasound of the heart (Doppler echocardiography) match results from a catheter test, which could help guide safer, more accurate valve care.
