Grossman's Cardiac Catheterization, Angiography, and ...
Regurgitant Fraction The angiographic assessment of severity of mitral
regurgitation also may be made more quantitative by calculation of the
regurgitant fraction. This entails measurement of total left ventricular stroke
volume (TSV) from the ...

Moss and Adams' Heart Disease in Infants, Children, and ...
For both methods, it is important to ensure that the entirety of the aortic
regurgitant velocity profile is obtained as partial display of the profile may result in
inaccurate representations of the deceleration slope and pressure half-time. It
should be ...
Patient respiration and cardiac motion cause translation of the aortic valve, which
prevents the CW Doppler beam from staying aligned with the regurgitant jet
throughout diastole. The CW Doppler alignment shown on the right is from a
more ...

Feigenbaum's Echocardiography
An example of how regurgitant volume and regurgitant fraction can be quantified.
See text for details. CSA, cross-sectional area; TVI, time velocity integral.

William F. Armstrong, Thomas Ryan, Harvey Feigenbaum, 2010
This calculation is not accurate (i.e., regurgitant volume is underestimated) if
there is substantial aortic regurgitation. In aortic regurgitation, the aortic valve
regurgitant volume is obtained by subtracting the mitral inflow stroke volume (Qs)
from ...

Cardiac Imaging Secrets
The PISA method is based on the principle of flow conservation: The volume of
blood that regurgitates through the mitral regurgitant orifice is equal to the volume
of blood converging toward the LV side of the mitral valve in systole. The PISA ...

Principles and Practice of Cardiac Magnetic Resonance in ...
When the main pulmonary artery is difficult to target for accurate measurement,
total pulmonary regurgitant volume and regurgitant fraction can be calculated by
adding the volumes measured for the right and left pulmonary arteries. However
...

The Practice of Clinical Echocardiography
The radius of the proximal isovelocity surface area zone measures 0.7 cm. The
aliasing velocity is 30.8 cm/s as displayed by the Nyquist limit. The peak
regurgitant flow rate = 2 × Π × (0.7 cm)2 × 30.8 cm/s = 95 mL/s. The regurgitant
orifice area ...

Textbook of Clinical Echocardiography: Expert Consult - ...
Fluid Dynamics of Valvular Regurgitation The fluid dynamics of a regurgitant
valve (Fig. 12-1) are, in many ways, similar to the fluid dynamics of a stenotic
valve and are characterized by: I Regurgitant orifice area (ROA) I High-velocity ...

Valvular Heart Disease
With this in mind, a representative regurgitant fraction can be calculated as
follows: Angiographic SV − Forward SV Regurgitant fraction = Angiographic SV
An RF of 20% is considered mild, 20–40% moderate, 40–60% moderately severe
, and ...
