2022年5月14日 · As your heart pumps blood, four valves open and close to make sure blood flows in the correct direction. As they open and close, they make two sounds that create the sound of a heartbeat. The four valves are the aortic valve, mitral valve, pulmonary valve and tricuspid valve. A heart murmur is often the first sign of a heart valve problem.

2024年12月7日 · Bicuspid aortic valve is a heart condition present at birth. That means it is a congenital heart defect. The aortic valve is between the left lower heart chamber and the body's main artery, called the aorta. Flaps of tissue on the valve open and close with each heartbeat. The flaps are called cusps.

What is bicuspid aortic valve? Bicuspid aortic valve is a type of abnormality in the aortic valve in the heart. In bicuspid aortic valve, the valve has only two small parts, called leaflets, instead of the normal three. This condition is present from birth. It can occur with other heart defects.

Bicuspid aortic valve (BAV) is a common congenital valvular malformation, which may lead to early aortic valve disease and bicuspid-associated aortopathy. A novel BAV classification system was recently proposed to coincide with transcatheter aortic ...

An aortic valve that has two leaflets instead of the usual three is called a bicuspid aortic valve. It is the most common congenital heart defect , meaning it is present at birth, but symptoms may develop in late childhood or during adulthood.

2015年8月21日 · The trileaflet mitral valve is a very rare congenital malformation with three equal size leaflets and three papillary muscles. In this article, we report the first case of trileaflet mitral valve associated with a bicuspid aortic valve in a patient …

2022年10月11日 · In patients with BAVs, the aortic valve complex is often eccentrically sized, with either a “flare” or “taper” upward from the aortic valve annulus. 49, 50 This is in contrast to trileaflet aortic valve anatomy, in which the most common configuration of the aortic valve complex is tubular, with consistent sizing through most elements.

2023年11月9日 · To characterise BAV-IE from a clinical and microbiological perspective and compare clinical outcomes with a cohort of individuals with trileaflet aortic valve infective endocarditis (TAV-IE).

2020年10月7日 · In this single-arm prospective study of 150 low-risk patients with bicuspid aortic valve stenosis undergoing TAVR using a self-expanding valve and a standardized sizing strategy, there was high device success with a low rate of death or disabling stroke at 30 days.

Calcific aortic valve disease (CAVD) encompasses the range of disease from initial alterations in the cell biology of the leaflets to end-stage calcification resulting in left ventricular outflow obstruction.
