Left ventricular assist device (LVAD) support is an accepted treatment of patients with end-stage heart failure. The increased applicability and excellent results with LVADs have revolutionized the treatment options available for such patients. Success with LVADs as bridge-to-transplant therapy has led to their successful use as an alternate to a transplant (ie, as destination therapy [DT]). The use of these devices as DT represents a relatively newer but growing indication. Until recently, most patients who have undergone LVAD implantation have been supported by pulsatile devices. Newer continuous-flow (CF) pumps have resulted in superior outcomes, including significantly reduced complication rates with improved durability over first-generation pulsatile design pumps. However, as with all new technology, the newer LVADs have introduced management challenges that were either unimportant or absent with pulsatile LVADs. This article reviews the current state of left ventricular devices, focusing on the CF pumps that currently dominate the field, including clinical outcomes, the physiologic and pathologic effects that are associated with CF pumps, and their unique management issues and complications.

The clinical use of the newer continuous-flow pumps for mechanical circulatory support have resulted in superior outcomes including significantly reduced complication rates with improved durability over first generation pulsatile design pumps. However, as with all new technology, the newer LVADs have introduced a different set of management issues, as well as a unique risk profile into the mechanical circulatory support arena that were previously absent or unimportant with pulsatile LVADs. These include the effects of continuous flow on the systemic circulation and end-organ function, risk of thromboembolism, and pump thrombosis related to contact bearings in the blood path, the possible increased incidence of gastrointestinal bleeding, and ventricular arrhythmias, as well as alterations in the unloading characteristics of continuous-flow devices. This manuscript overviews the physiologic and pathologic effects that are associated with continuous-flow pumps and their unique management issues and complications.

Несмотря на это, клиника применения данных насосов в ряде случаев столкнулась с проблемами, связанными с данной технологией. Все это стимулировало развитие нового направления по разработке новых принципов управления роторными насосами, основанных на модуляции скорости оборотов на-сосов. В статье проведен анализ негативных факторов клинического применения насосов непульсиру-ющего потока и обзор методов оптимизации управления насосами, основанных на модуляции скорости выходного потока.Ключевые слова: механическая поддержка кровообращения, терминальная сердечная недостаточность, роторные насосы, модуляция выходного потока, система управления насосами. 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.
