Ultrasound vs X-ray guided aortic valve replacement
Part of Heart & circulation clinical trials.
This trial compares two methods (ultrasound vs X-ray) to guide a minimally invasive heart valve replacement procedure for people with severe aortic stenosis. The goal is to see if using ultrasound alone is as safe and effective as using X-ray.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 70 or older with severe aortic valve narrowing causing symptoms or weak heart pumping, OR you are 65-69 with high surgical risk or conditions that make open-heart surgery unsafe.
- Your heart structure must be suitable for the minimally invasive valve procedure and you must be able to tolerate an ultrasound probe in your throat (transesophageal echo).
- You must have signed consent and be willing to participate.
- You cannot have certain serious heart or other conditions, such as recent heart attack, stroke, infection, or kidney failure needing dialysis.
- You should not be in another drug or device study.

This trial is testing a new way to replace your aortic valve using a small tube through your armpit, guided only by ultrasound (echocardiography) instead of X-rays. It may be an option if you have severe aortic stenosis and are a good fit for this less invasive approach.
This trial tests two types of replacement heart valves (self-expanding and balloon-expanding) in people who have severe aortic stenosis (tight heart valve) and an enlarged aorta (the main blood vessel from the heart). The goal is to see which valve type works better for these patients.
This study tests a new way to use X-ray images during a TAVI procedure to check how well the new valve is working right away. It may help doctors make real-time adjustments to improve the outcome.
This trial tests a minimally invasive procedure called TAVI (transcatheter aortic valve implantation) to replace a narrowed aortic valve without requiring open-heart surgery. The study is checking whether TAVI can be safely performed at hospitals that don't have cardiac surgery units on-site.
This study tests a catheter-based procedure to replace a narrowed aortic valve without traditional open-heart surgery. It's designed for patients who are at higher risk for surgery due to age, health conditions, or anatomy.
This trial tests if a heart valve replacement procedure called TAVI can be safely done at heart centers that do not have a full heart surgery team available onsite. It is for people with severe narrowing of the aortic valve who are already planned for TAVI through the leg artery.
