In principle, the blood volume passing through a stenotic valve (aortic stenosis) is equal to the blood volume proximal to the stenosis or in the LVOT (Figure 4). The stroke volume is equal to ...

The diagnosis of aortic stenosis is made mostly on physical examination and by echocardiography. The ECG in patients with aortic stenosis frequently shows left ventricular hypertrophy with strain ...

The echocardiogram can also quantify aortic stenosis severity. Two-dimensional echocardiography can demonstrate a thickened aortic valve, reduced leaflet mobility and concentric left ventricular ...

Background Aortic stenosis is a degenerative condition with high mortality in its severe stages and no preventive treatment.

Whether transcatheter aortic-valve replacement can improve outcomes in patients with asymptomatic severe aortic stenosis has been unclear. New research findings comparing TAVR with clinical ...

Aortic stenosis, affecting nine million people globally, is often unnoticed as symptoms are mistaken for aging. This heart condition, common in elderly, restricts blood flow due to valve narrowing ...

DAVID MONTGOMERY: 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 ...
