Simultaneous LV and Ao pressure tracings in a patient with minimal Ao stenosis (0 to 200 mm Hg scale) are shown in Figure 3-33. The pressures were measured with a Millar high-fidelity catheter with two transducers on the tip of the catheter (see Chapter 6 ). Peak-to-peak Ao-LV pressure difference is only 10 mm Hg.

MRI turns out to be a wonderful test for quantifying aortic stenosis because it’s totally not invasive, doesn’t require the use of contrast, and there’s no risk of stroke like there is with cardiac catheterization. Here are the results of the automatic segmentation. You can see the segmentation is good. I’m going to go ahead and now ...

TOE is rarely required to assess aortic stenosis, but has use in the assessment of patients for TAVI. 3D TOE can facilitate accurate measurements of the aortic valve annulus and important characteristics such as proximity of the left main stem, combined with an assessment of calcification, and has been shown to provide equivalent information to that obtained by cardiac …

It occurs in ≈2.8% of patients ≥75 years of age and can occur because of degenerative calcification and congenital valvular defects such as bicuspid AVs or rheumatic disease. 1 – 3 Calcific aortic stenosis (AS) is associated with increased leaflet stiffness and a narrowed AV orifice, resulting in increased pressure gradients across the valve.

The optimal method to measure the transaortic gradient in a patient with aortic stenosis is a simultaneous left ventricular (LV) pressure and central aortic (Ao) pressure with side-hole catheters. Shown are examples in which alternative methods are used to obtain the pressures, which produce erroneous results.

However, hypertension has been shown to be independently associated with degenerative calcific aortic valve sclerosis and stenosis in elderly population based studies. 1, 2 Furthermore, in a recent series hypertension was found in one third of patients suffering symptomatic severe AS. 3 In the absence of specific cohort studies, the nature of the association between AS and high …
