title: [Noninvasive registration of turbulent flows in the left ventricle].
abstract: Observation results of 133 patients with chronic heart insufficiency and 29 healthy people, all aged 41 ± 6 years were analyzed. 51 patients had ischemic heart disease, 53 had various valvular diseases and 30 patients had dilated cardiomyopathy. Echocardiography was performed together with ECG. Blood flows in left ventricle, myocardium shift velocity and pressure gradients during the heart cycle were measured. The study showed that systole leads to the directional change of blood flows within the heart cycle, accompanied by turbulence phenomenon with extremely high flow velocities. Detection of vortex flows and velocity vector characterizes changes of flow direction. All patients of the main group were operated on with the use of modern methods of heart remodeling. The principally novel method of surgical treatment, allowing to preserve the patient's heart, was worked out.
