The research area of aortic valve focuses on studying the structure, function, and diseases affecting the aortic valve. The aortic valve is one of the four valves in the heart that helps regulate blood flow from the left ventricle to the aorta. Research in this area aims to understand the mechanisms behind aortic valve diseases such as stenosis (narrowing) and regurgitation (leaking), as well as develop new treatments and interventions to improve outcomes for patients with these conditions. This research is often conducted using a combination of clinical studies, imaging techniques, and molecular biology approaches to better understand the complex biology of the aortic valve.
