High blood flow velocity across the stenotic aortic valve in an elderly patient compatible with a mean pressure gradient of about 60 mm Hg and a valve area of about 0.6 cm2 calculated by the ...

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

Conclusion: This proof-of-concept study demonstrated that aortic pressure alone can be used to detect severe AS. A larger analysis is needed to validate these findings across gradients of severity.

Patients with severe AS were stratified into high- and low-gradient (HG, mean aortic gradient [MG] ≥40 mm Hg; LG, MG <40 mm Hg). Rates of Heart Team evaluation within 60 days and aortic valve ...

Peak and mean pressure gradients (MPGs) in the left ventricular outflow tract (LVOT ... There was a significant, but no strong correlation between the mean aortic gradient at 100 W and the PPEC (R = 0 ...

Most children who have had an aortic valve repair or replacement live active, healthy lives. Your child’s activity levels, appetite, and growth usually return to normal. Your child should get regular ...

A small percentage of malfunctioning congenitally abnormal aortic valves are unicuspid or unicommissural,5 but as most reports do not distinguish this from bicuspid aortic valve the abbreviation ...

In this study, a capacitive pressure sensor with concentration gradient structures is designed and fabricated by a novel acoustic resonance mixing method. The concentration gradient structures ...
