Possibilities of doppler echocardiography in heart diseases

Doppler echocardiographic study allows you to determine the direction of the flow, its nature (laminar or turbulent) and speed in the projection of all heart valves. The parallel use of Doppler echocardiography compensates for the shortcomings of one- and two-dimensional methods in detecting valvular regurgitation, helps to detect signs of interventricular and interatrial shunting in case of suspected congenital heart disease, and allows non-invasive calculation of transvalvular pressure gradients in heart disease. The correct assessment of hemodynamics and valvular apparatus of the heart, the exact localization of the studied flow contribute to the objectification of the assessment of the pathological process. With combined heart defects, doppler echocardiography is a more informative method than radiography and one- and two-dimensional echocardiography, and may be the method of choice when deciding on the indications and nature of the surgical correction of the defect.
