A finding of reduced aortic-valve leaflet motion was noted on computed tomography (CT) in a patient who had a stroke after transcatheter aortic-valve replacement (TAVR) during an ongoing clinical ...

Subclinical leaflet thickening and reduced leaflet motion of bioprosthetic aortic valves have been documented by four-dimensional computed tomography (CT). Whether anticoagulation can reduce these ...

WASHINGTON, DC—Subclinical leaflet thrombosis occurs “frequently” in patients who received bioprosthetic valves for the treatment of aortic stenosis, with the problem occurring more commonly in ...

About 12 percent of patients undergoing aortic valve replacement developed non-symptomatic blood clots around the valve leaflets (known as subclinical leaflet thrombosis) that reduced the motion of ...

Heart valve replacements made from tissue (bioprosthetic valves) have long been thought to be spared the complication of blood clot formation. Researchers have now found that about 15 percent of all ...

PARIS, France—In a small, feasibility study, a new percutaneous device used to fracture calcium deposits in patients with degenerative calcified aortic stenosis to improve leaflet mobility had a ...

There are three types of bicuspid aortic valves — types 0, 1, and 2. Experts classify these types based on whether the leaflets of the valve have fused to form a ridge. A bicuspid aortic valve is a ...

Aortic valve disease is a condition that occurs when your aorta (the main artery of your body) and left ventricle (the lower left chamber of your heart) malfunction. The aortic valve determines how ...

"Aortic valve stenosis in people with two leaflets is therefore clearly a very different disease than in people with three leaflets," concludes Brandtner. The researchers hope their findings will ...

A bicuspid aortic valve is a congenital heart defect where the aortic valve has 2 leaflets instead of 3. It affects about 1% of people and can raise the risk of valve problems later in life. To keep a ...
