,Conclusion: Keepin’ on Keepin’ on,which 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

Comparisons and Computational Resultsraphy (2D-Doppler). At least in the United States we are still debating whether 2D-Doppler offers significant practical advantages over the ‘conventional’ pulsed and continuous wave Doppler techniques (V-mode*) in adult patients. The purpose of this review is to examine the advantages and limitation

However, no direct information on blood flow is obtained and the hemodynamic consequences of minimal structural and functional abnormalities cannot be assessed. This is most apparent for lesions, such as valvular insufficiency and in
