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 aortic valve area can be calculated and ... of 12 mm or greater suggests absence of critical stenosis. Heavy calcification reduces the accuracy of planimetry for valve area measurement ...

When aortic stenosis occurs, there is a tightening and oftentimes calcification of the aortic valve and that leads that valve to not be pliable but very rigid. And when the valve can't open ...

The chest radiography may reveal a normal cardiac size since the hypertrophy in aortic stenosis is concentric. However, once LV systolic failure occurs, cardiomegaly will be seen. Calcification of ...
