Heart artery checks during aortic valve replacement

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 trial compares two approaches for replacing a tight aortic heart valve (TAVI) through a leg artery: doing it with or without a routine check of your heart's arteries (coronary angiogram). If you have severe aortic stenosis and are scheduled for TAVI, this study helps find out whether skipping the artery check is safe and effective.

This study checks whether special heart tests can better understand “in-between” blocked heart arteries before and after TAVI (a valve replacement done through a catheter). It may help doctors choose the safest, most accurate treatment when coronary artery disease is unclear.

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 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 trial studies heart imaging tests (from multiple types of scans) for people who have a narrowed aortic valve and are being checked for a valve replacement through the catheter (often called TAVI). It may help doctors better plan the procedure and understand heart function before treatment.
