A small statistically significant difference in aortic valve area was noted at 1 year after TAVR.
To evaluate AS, we measured maximum (AV Pg max) and mean (AV Pg mean) transvalvular pressure gradients, effective orifice area (EOA) using linear equation and aortic valve area (AVA) using planimetry.

In present study there was a progressive increase in Natriuretic peptide levels with decreasing aortic valve area, but a significant increase in Natriuretic peptide levels in patients with an ejection of <40%, emphasize the important association between LV systolic function and Natriuretic peptide level.
There was aortic regurgitation with an aortic valve area of 2.27 cm [sup]2 .
The echocardiogram at the time of his diagnosis in 2007 had revealed an aortic valve area of 1.2-1.3 [cm.sup.2].
During a mean 21 months of follow-up, the echocardiographically determined annualized rate of decrease in aortic valve area was twice as great in the statin nonusers (Circulation 104[18]:2205-09, 2001).
Her preoperative transthoracic echocardiogram revealed an ejection fraction of 60%, aortic valve area of 0.5 [cm.sup.2], mean gradient of 59 mm Hg, and left ventricular outflow tract area of 1.7 cm.
An echocardiogram at that time revealed normal left ventricular size and function, no aortic insufficiency, mean transaortic gradient 12 mmHg, and calculated aortic valve area 1.0 [cm.sup.2] (Video 4, Figure 3).
Criteria for severity of aortic valve stenosis included aortic valve area (AVA, [cm.sup.2]), calculated using the continuity equation; AVA indexed for body surface area (AVA/BSA, [cm.sup.2]/[m.sup.2); and mean transvalvular pressure gradient and peak aortic jet velocity (Umax).
