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

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

Doppler stroke volume was calculated from vessel diameter and the integ
