ABSTRACT

Until recently hemodynamic assessment of the heart had to be done invasively by catheterization. Nowadays echocardiography with Doppler has demonstrated to give similar results by a non-invasive approach. The methods to determine several hemodynamic parameters by echocardiography without Doppler are discussed (dimensions of the cavities, left ventricular mass, ejection fraction) as well as with use of Doppler (cardiac output, quantification of valve regurgitation and stenosis, pressure gradients, valve area and intracardiac pressure). Basic formulas such as the continuity and simplified Bernouilli equations are discussed.
