An aortic stenosis murmur is an unusual sound the heart makes due to a narrowing of the aortic heart valve. The narrowed heart valve restricts blood flow from the heart, which can create a murmur.

Aortic stenosis is a condition affecting the aortic valve—the valve positioned between the heart’s main pumping chamber and the aorta—causing it to narrow, or become stenotic.

Being older is a risk factor for aortic stenosis due to calcium buildup in the valve and scarring. This usually begins after a person is 60 years old, with symptoms appearing at 70–80 years old.

Severe aortic stenosis is usually defined as an aortic valve area (AVA) of 1.0 cm 2 because at this degree of stenosis the peak resting gradient often approaches 50 mm Hg.

In a surgical first, doctors have replaced a heart valve through a small neck incision using robotic assistance, avoiding the ...

Aortic stenosis is a narrowing of the aortic valve that affects how blood flows through the heart and body. While not often linked to heart valve narrowing, high and irregular blood pressure can ...

Aortic stenosis (AS) is a decrease in the effective area of the aortic valve leading to increased resistance to the flow of blood across the valve. [1, 2] It is relatively common in the elderly ...

Calcific aortic stenosis in the elderly is the number one cause of surgical valve replacement in the US and Europe. The incidence of calcific aortic stenosis is increasing as the general age of ...

In a new study published in JACC: Advances, researchers at Beth Israel Deaconess Medical Center (BIDMC) successfully validated an artificial intelligence tool that detects severe aortic stenosis ...

Using a Mendelian randomization design to assess the genetic and observational association between obesity and aortic valve stenosis, researchers found that patients with allele scores between 4 ...

Lipoprotein (a) was associated with prevalent and incident aortic valve calcification and calcium progression in participants without aortic stenosis, researchers reported.“Lp (a) may represent ...
