Definitions and Existence Theoremsuences of minimal structural and functional abnormalities cannot be assessed. This is most apparent for lesions, such as valvular insufficiency and intracardiac shunts, which cannot be diagnosed by echocardiography alone with confidence.

Main Goals and Proof Techniquesed with the aid of which malfunctions may be detected and assessed. This investigation deals with the use of this method as applied to functional assessment of mechanical and biological mitral valve prostheses.

PRISE

Estimation of transvalvular pressure drops by Doppler echocardiography: the Bernoulli equation revis they estimated the blood flow velocity at the orifice by an invasive pressure drop measurement. The application of Bernoulli’s equation has received renewed interest because pressure drops across stenotic valves are now being estimated using non-invasive blood velocity measurements by Doppler echocardiography.

Factors influencing fluid velocity measurements in valvular regurgitationt..Inherent properties of the spectral analysis of the Doppler signal, in combination with a small core flow volume will create difficulties in distinguishing high regurgitant velocities from background noise.

Color-coded Doppler flow imaging: a major advance for non-invasive cardiology?uences of minimal structural and functional abnormalities cannot be assessed. This is most apparent for lesions, such as valvular insufficiency and intracardiac shunts, which cannot be diagnosed by echocardiography alone with confidence.

ALTER

Estimation of transvalvular pressure drops by Doppler echocardiography: the Bernoulli equation reviswhich was already formulated by Bernoulli, a Dutch born mathematician, in the 18th century, for the calculation of the orifice area. In their approach they estimated the blood flow velocity at the orifice by an invasive pressure drop measurement. The application of Bernoulli’s equation has received
