Sentence examples for mean aortic gradient from inspiring English sources

Echocardiography demonstrates left ventricular hypertrophy, an ejection fraction of 50%, no evidence of mitral regurgitation, and severe aortic stenosis (AS) with a peak aortic gradient of 4.8 m/s (92 mm Hg) and a mean aortic gradient of 55 mm Hg.

A repeat TTE, 4 months after TAVI, showed a stable bioprosthetic valve with a mean aortic gradient of 8.5 mmHg and no regurgitation.

In multivariable linear regression higher LV mass/height2.7 at the last study echocardiogram was associated with male sex (β=0.06), and higher mean aortic gradient (β=0.15), systolic blood pressure (β=0.04), body mass index (β=0.14), initial LV mass/height2.7 (β=0.54), and presence of normal midwall shortening (β=0.05, all P<0.05) at the baseline echocardiogram.

Of note, electrocardiographic strain pattern was not significantly associated with either cardiovascular death or all-cause mortality when mean aortic gradient was included as covariate in their multivariable models, in contrast to the strong independent association with echocardiographic LV mass and hypertrophy reported in the present article.

However, he developed rapidly progressive AS: in 2005, the maximum aortic velocity on transthoracic echocardiogram (TTE) was 2.1 m/sec, increasing to 5.1 m/sec in 2008, with a mean aortic valve gradient of 66 mmHg.

In subsequent models replacing energy loss index by peak aortic jet velocity, mean aortic valve gradient, or aortic valve area as measure of AS severity, or LV ejection fraction by midwall shortening or stress-corrected midwall shortening, the results did not change (data not shown).

All patients underwent postoperative transthoracic echocardiography (TTE) evaluation of the mean aortic valve pressure gradient 6 weeks after surgery.

In the case of the heart, the mean aortic to coronary back pressure (vide infra) gradient divided by total sinus coronary blood flow yields total coronary resistance (mmHg mL min−1), although it must be acknowledged that Thebesian flow draining directly to the ventricular and atrial cavities is unaccounted for [ 93].

Overall, the mean aortic valve area was 1.0 mm2, and the mean pressure gradient was 26 mmHg in the AS group (Table 1).

In contrast, at ECHO 2005, 20 out of 51 (39%) patients had developed aortic stenosis (mild (13), moderate (3), and severe (4)) with an estimated mean aortic valve area of median 1.6 cm (range 0.6 3.2 cm) and a mean valvular gradient of 11 mmHg (range 5 45 mmHg).

During a median of 4 years follow-up, AS progression rate did not differ between women and men, whether assessed from peak aortic jet velocity, mean transvalvular gradient, aortic valve area, aortic valve area index or ELI (table 2).
