Studying a new sizing method for bicuspid aortic valves
Part of Genetic & congenital, Heart & circulation clinical trials.
This trial looks back at people with a specific type of bicuspid aortic valve (a valve with two flaps instead of three) who had a transcatheter aortic valve replacement. Researchers want to see how well a special sizing method called LIRA worked for choosing the right valve size.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have severe aortic stenosis (a narrowed heart valve).
- Your aortic valve is bicuspid type 1 or 2 (a valve with two flaps).
- You had a transcatheter aortic valve replacement (TAVR) between September 2018 and June 2024.
- The valve used was a self-expanding, supra-annular type sized with the LIRA method.
- You did not have a repeat TAVR, an emergency TAVR, or TAVR for a leaky valve (aortic regurgitation).

This trial compares a less invasive valve replacement (TAVR) with traditional open-heart surgery for people with a specific type of severe aortic valve narrowing (bicuspid valve). It aims to see which approach works better for those at intermediate or low surgical risk.
This trial tests two different ways to repair a leaky bicuspid aortic valve (a valve with two flaps instead of three). The goal is to see which repair method works better. If you need surgery for a severely leaking valve and your valve is the right shape, you may be able to join.
This study looks at people with a bicuspid aortic valve (a valve with two flaps instead of three) in Chinese patients. It collects information about this condition to better understand it.
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.
This study tests a special sizing method (ABC algorithm) to help doctors select the right valve for people with a bicuspid aortic valve. It aims to improve outcomes for those getting a Sapien 3 valve through a catheter (TAVR).
This trial compares a “smaller valve sizing” approach versus the usual sizing method during TAVR (a catheter-based valve replacement) for people with bicuspid aortic stenosis. The study aims to see which method improves safety and outcomes for the right valve fit.
