The mean pressure gradient is derived from the average ... is automatically provided in the software from tracing of the aortic stenosis velocity envelope. The peak velocity is sensitive to ...

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 ...

Each heavy vertical line represents two-tenths second. Note the double systolic sound associated with the double summit of the pulsus bisferiens in this case of severe aortic stenosis. The purpose ...

The cause of the reversed flow in these circumstances can be attributed to a fall of pressure distal to the stenosis below that at the vertebral-basilar junction so that the pressure gradient in ...

A large new population study of men over 45 indicates insulin resistance may be an important risk factor for the development ...

So the treatment for mild and moderate aortic stenosis really is aimed at preventing the progression of the disease. And so we aim to lower cholesterol. Keep the blood pressure down. If people ...

The SMART trial raised questions about balloon-expandable valves in small aortic annuli; these new data offer some answers.

as well as significant secondary mitral regurgitation and aortic valve stenosis, with mean and peak pressure gradients of 14 and 22 mmHg, respectively. CT angiogram confirmed these findings ...
