Comparing CT scan measurements to surgery findings for aortic valve replacement
Part of Heart & circulation clinical trials.
This study checks if measurements taken from a CT scan before surgery match the actual size of the valve measured during surgery. It may help doctors choose the best valve size for people with severe aortic stenosis who need valve replacement.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years old or older.
- Your aortic valve is severely narrowed (severe aortic stenosis).
- You are scheduled for surgery to replace your aortic valve.
- Your aortic valve has three flaps (not two).
- Your kidneys are working well (no chronic kidney disease).
- Your body mass index (BMI) is 30 or less (weight in proportion to height).

This study uses a CT scan (with contrast dye) to measure the coronary artery openings after people have a new aortic valve placed surgically. It aims to see how to best plan or understand coronary blood flow after the surgery.
This study uses a CT scan plus a personalized computer model to plan a less invasive valve replacement (TAVR). It may help doctors better prepare for the procedure using simulation before your valve is placed.
This trial compares different methods to evaluate coronary artery disease in patients planning to have a transcatheter aortic valve replacement (TAVR) for severe aortic stenosis. The goal is to find out if a less invasive approach is as safe and effective as the standard one.
This study checks whether an “investigational” transcatheter aortic valve is safe and works well for people with severe, calcified aortic stenosis (a stiff, narrowed heart valve). It may help improve valve function and symptoms, but you must meet specific heart, scan, and health-status requirements.
This study looks at whether a CT scan of the chest before aortic valve replacement surgery (with or without bypass) can help doctors plan the procedure better. It is for people with severe aortic valve stenosis who are already scheduled for surgery.
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.
