Summary:The method of mechanical circulation support using non-pulsating fl ow pumps, built on the principle of rotary (centrifugal and axial) pumps, took the leading direction (94%) in the world clinical practice for the treatment of the patients with terminal heart failure. Despite this, the clinic application of these pumps in a number of cases faced with the numbers of negative problems associated with this technology. This is stimulated of a new direction of principles for a control of the rotary pumps, based on the modulation of the speed pumps. The article analyzes the negative factors of the clinical application of non-pulsating fl ow pumps and gives an overview of the methods the optimization of the control pump based on the modulation of the output fl ow.
