The Vmax and mean aortic PG were calculated using the simplified Bernoulli equation. The AVA was calculated using the standard continuity equation and normalised to body surface area.15 The follow-up ...

Therefore, maximum or peak instantaneous gradient is derived using the simplified Bernoulli equation: p=4V 2 as described below (Figure 2). Planimetric technique in measuring aortic valve area ...

Resting LVOT peak velocity was measured by using continuous-wave Doppler echocardiography, and the LVOT pressure gradient peak estimated by using a simplified Bernoulli equation. The maximal LVOT ...

One concern is that the simplified Bernoulli equation, the 4v 2 formula used to convert velocity to pressure gradient, assumes a narrow orifice between the two chambers whereas with severe TR, the ...

2.1 Effect of axial load on vibration modes and frequencies Here will be shown as the vibration modes and natural frequencies are altered when the internal loads are increased in a Euler-Bernoulli ...

Whether you’re new to smart home, just bought a new home or are looking to get creative with smart lighting, Hubspace has curated three product bundles to meet you exactly where you are in your tech ...

Specifically, for a single-joint robotic fish, the hydrodynamic forces on the tail are analyzed using the DVM and calculated using the unsteady Bernoulli equation. And for the fish head, the ...

PASP was calculated using the peak TR velocity (m/s) and assuming a right atrial pressure of 5 mm Hg using the simplified Bernoulli equation. The primary outcome of interest was development of cardiac ...
