Severe aortic stenosis is usually defined by an aortic valve area (AVA) < 1.0 cm2 and a mean transvalvular gradient ≥ 40 mmHg in symptomatic patients. Low-flow aortic stenosis is typically observed in ...

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 ...

In almost all patients with aortic stenosis two gradients combine to form the total pressure overload on the left ventricle. [13, 14] One pressure drop occurs at the valve itself, a hemodynamic ...

Your aortic valve plays a key role in getting oxygen-rich blood to your body. Aortic valve stenosis is a common and serious heart problem when the valve doesn’t open fully. Learn about what ...

The most difficult group of patients with aortic stenosis to care for is patients with reduced ejection fraction, heart failure, and low transvalvular gradient. While there are no specific studies ...

Low aortic valve gradient is a result of aortic stenosis, a narrowing of the opening of the aortic valve. This condition results in restricted blood flow from the left ventricle to the aorta, the ...

It also revealed stenosis of the aortic valve. The opening to the artery is only 1.3 cm, compared with a normal opening of around 3.3-3.5 cm. The mean gradient is 10 mm Hg.

Low aortic valve gradient and LV dysfunction are commonly seen in patients undergoing TAVR, but only the former is independently associated with poorer outcomes in the first year following the ...

Low aortic valve gradient is a result of aortic stenosis, a narrowing of the opening of the aortic valve. This condition results in restricted blood flow from the left ventricle to the aorta, the ...
