Web6 feb. 2024 · The following are key points to remember from this article on reconciling echocardiography, computed tomography (CT), and hybrid imaging in assessing discordant grading of aortic stenosis (AS) severity: There is no single modality or parameter able to accurately grade AS severity in all patients. WebIn most elderly adults, aortic stenosis is caused by a build-up of calcium on the valve leaflets. Over time, this causes the leaflets to become stiff, reducing their ability to fully open and close. Birth Defects A normal aortic valve contains three leaflets. But sometimes people are born with an aortic valve that has one, two, or four leaflets.
