As your heart beats, it pumps blood from the left ventricle through the aortic valve and into the aorta, your body’s largest artery. The aortic valve is made up of three triangular flaps of ...

Large and rare duplications and deletions in a chromosome region known as 22q11.2 , which involves genes that regulate ...

Aortic stenosis is a tightening of one of the four major valves of the heart. The aortic valve is particularly important because the aortic valve is the gateway to the rest of the body.

Large and rare duplications and deletions in a chromosome region known as 22q11.2 , which involves genes that regulate ...

The first phase of the project, presented in this manuscript, consisted of a cross-sectional study aiming to evaluate valve function ascending aortic dimensions and establish the prevalence of aortic ...

Surgery to replace an aortic valve is done for aortic valve stenosis and aortic valve regurgitation. During this surgery, the damaged valve is removed and replaced with an artificial valve. The valve ...

This abnormal backflow of blood leads to pathologic changes in the heart — remodeling ... transcatheter aortic valve replacement (TAVR; see the “Treatment” section below), although ...

The heart valve can calcify and cause narrowing of the valve which is called stenosis. Stenosis happens most often in the aortic valve, but can occur in any of the heart’s four valves. When a healthy ...

Long-axis parasternal view, revealing the intensity of calcification and doming of the aortic cusps in systole. Left ventricular outflow tract (LVOT) diameter may be measured for valve area ...

Aortic stenosis occurs when the orifice of the aortic valve is significantly ... as described later in this section. Dyspnea on exertion indicates early heart failure. Both systolic and diastolic ...
