[Determination of the right ventricular volume and ejection fraction by echocardiography (a comparison with angiographic data)].

The determination of function of all cardiac chambers is important in clinical practice. The improvement of the method of two-dimensional echocardiography permitting visualization of the right ventricle (RV) in different topographic projections made possible ultrasonic assessment of RV function. The RV volume and ejection fraction were determined by two-dimensional echocardiography in 25 patients and the results obtained were compared with contrast ventriculography findings. Taking into account the complexity of geometrical shape of the right ventricle its volume based on the results of echocardiography, equaled the sum of the volumes of 3 figures: 2 frusta and one cone. Comparing the results obtained by two methods, significant correlation of all indices characterizing RV function (r-0.85-0.89) was revealed. The prospects of future development of the calculation of RV volumetric indices by the results of two-dimensional echocardiography were discussed. Limitations of the use of this method were described.
