[Methodological aspects of contrast echocardiography].

Contrast echocardiography was applied in the examination of 38 patients with various congenital and acquired heart diseases. The dye cardiogreen and physiological saline solution were used as the contrast medium. The technique of contrast echocardiography is described. It is shown that the method of contrast echocardiography allows one to visualize the direction in which the intracardiac streams of blood move, which makes it possible to use the method in the diagnosis of septal defects and cardiac valve insufficiency.
