Long-term follow-up of the VitaFlow heart valve
Part of Heart & circulation clinical trials.
This study is a long-term follow-up for people who took part in the original VitaFlow heart valve trial at certain hospitals. It checks how well the replacement valve is working over time.

This study follows how the VitaFlow heart valve works in people age 70+ who have severe, narrowed aortic valves and cannot safely get open-heart valve surgery. It’s meant to see whether the device improves outcomes and is safe over time.
This trial tests a new valve replacement device (VitaFlow Liberty) that is inserted through a tube in an artery, avoiding open-heart surgery. It is for people with severe aortic stenosis who are at high risk for traditional surgery.
This trial tests a new delivery system (VitaFlow Liberty Flex) for placing a replacement aortic valve in people with severe aortic stenosis. It is designed for patients whose heart anatomy (a steep angle between the heart and aorta) makes the procedure more challenging.
This trial is testing a new, less invasive way to replace a narrowed aortic valve using a special device. The goal is to help improve blood flow and reduce symptoms like chest pain and shortness of breath.
This study is following people with heart valve disease (leaky or narrowed valves) to understand how the disease changes over time and what problems it may cause. It does not test a new treatment, but helps doctors learn more about valve disease progression.
This study tests a new type of heart valve (called Venus-Neo) to see if it is safe and works well for people who need their aortic valve replaced. If you qualify, you may receive this valve as part of the study and be followed over time to ensure it is working properly.
