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 ...

The study published in the European Heart Journal—Cardiovascular Imaging, analyzed data from 601 patients with severe high-gradient AS who underwent cardiac CT scans. While it was found that ...

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).

Compared with usual care, a system of electronic provider notification more often enabled patients diagnosed with severe ...

The 8-year data may hold value for TAVI—the newest Sapien valve uses the same tissue—but many other variables differ.

In principle, the blood volume passing through a stenotic valve (aortic stenosis ... 0.80/4.57 0.18 indicative of severe aortic stenosis.Pk Grad=peak gradient; Mn Grad=mean gradient ...

A new method of alerting clinical care providers holds promise for increasing treatment and improving survival for patients with severe aortic stenosis (AS), a valvular heart condition that can be ...

Medtronic has reported late-breaking data from the randomised Evolut Low Risk Trial’s five-year outcomes of the Evolut transcatheter aortic valve replacement (TAVR) system in low-risk aortic ...

Healthy valves open wide to let blood move freely through the heart and body. They then shut tightly until the next heartbeat. If you have aortic regurgitation, the flaps around your aortic ...

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 ...
