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 ...

If the transvalvular gradient increases with output, severe aortic stenosis is present and valve replacement may be beneficial. However, if output increases but gradient does not, only mild ...

An echocardiogram shows normal systolic function and a heavily calcified aortic valve. The patient's peak Doppler transvalvular gradient is 64 mm Hg, with a mean gradient of 50 mm Hg. His ...

In patients greater than age 65, more than 90% of aortic stenosis involves trileaflet valves which have developed heavy calcification. [5] In these instances the calcium deposits are thought to ...

Coronary blood-flow patterns are abnormal owing to an increased left ventricular mass and a reduced diastolic pressure gradient. Rheumatic aortic stenosis is usually accompanied by mitral-valve ...

Management of adults with BAV Patients with BAV should be monitored by echocardiogram every 1-2 years, depending on the degree of pressure gradient across the aortic valve. Patients with mild ...

Patients with a combination of left ventricular dysfunction and low aortic valve gradient, or reduced force of blood flow through the aortic valve, have higher mortality rates and a greater risk ...

WASHINGTON, DC—Invasive hemodynamic assessment may help better identify severe aortic stenosis in patients with low aortic flow/low transvalvular pressure gradients and preserved ejection fractions, ...

The most important hemodynamic parameters for staging are the maximum transaortic velocity (V max), the mean pressure gradient (ΔP) across the aortic valve, and the aortic valve area (AVA).

(HealthDay News) – While all-cause mortality is high in low-flow, low-gradient aortic stenosis patients receiving transcatheter aortic valve implantation (TAVI), surviving patients show ...
