title: [Study of hemodynamics after creation of a new experimental outflow tract for the left heart ventricle].
abstract: Experimental analysis was made of hemodynamic changes occurring in the left heart and systemic circulation after making an aorto-left-ventricular shunt while simulating the complete obstruction of an outflow segment in the left ventricle. The hemodynamics of the left cardiac cavities in a "new operation" was studied. Analysis of the recording of pressure curves in the aorta, large arteries, and left ventricle, of electromagnetic flowmetric, echo-, and Doppler cardiographic findings suggested good results of the operations in the periods up to 12 months. The proposed model of an experimentally induced artificial aorto-left-ventricular shunt with conduit allows one to test and study the functional state of various types of prosthetic valves (biological and artificial) in long periods after surgery.
