Sentence examples for mean transvalvular gradient from inspiring English sources
Methods: We studied by echocardiography Doppler 22 patients (mean age 12.4 ± 5.6 years) with peak and mean transvalvular gradient of 63 ± 6 and 32 ± 4 mm Hg, respectively.
> -wrap-foot> The postoperative mean transvalvular gradient was significantly higher in the Mosaic group (24 ± 9 mmHg vs 17 ± 7 mmHg; P < 0.001; Fig. 1).
The postoperative mean transvalvular gradient was significantly increased in the Mosaic group (24 ± 9 mmHg vs 17 ± 7 mmHg; P < 0.001).
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).
4 11 Severity of AS was evaluated by peak aortic jet velocity, mean transvalvular gradient, aortic valve area and aortic valve area indexed for body surface area, as well as pressure recovery adjusted aortic valve area index, i.e. the energy loss index (ELI).
Clinical, hemodynamic, and periprocedural complications and follow-up mortality data were collected and compared between patients with low mean transvalvular gradients (≤40 mm Hg, n = 170 [63%]) and high transvalvular gradients (>40 mm Hg, n = 100 [37%]).
A transthoracic echocardiography showed severe aortic valve stenosis with the aortic valve area (AVA) of 0.83 cm2 and the mean transvalvular pressure gradient of 38 mmHg.
20 Doppler assessment of AS included measurement of peak and mean transvalvular velocities and gradients; aortic valve area by the continuity equation, indexed for body surface area; and pressure recovery adjusted aortic valve area (ie, energy loss index (ELI)) calculated by a previously validated formula.
The valve demonstrated excellent function with a low transvalvular gradient.
Valvular area decreases 0.3m/s/y, transvalvular gradient (7mmHg/y) and blood speed 0.3m/s/y) increases with age.
Surgery or transcatheter aortic valve implantation treatment and high baseline transvalvular gradient are associated with EF improvement.
