AbstractWhile use of mechanical circulatory support is increasing, knowledge of its fundamental role and limitations remains poorly understood by many medical professionals. This article summarises the main types of mechanical circulatory support and how they work, particularly focusing on the key information medical professionals should know should they encounter them in hospital. Mechanical circulatory support can be an effective treatment modality in selected pathologies, including myocardial ischaemia, pulmonary congestion, massive pulmonary embolic disease, postcardiotomy cardiogenic shock with failure to wean off bypass, right ventricular failure, bridge to heart and lung transplant and, increasingly, extracorporeal cardiopulmonary resuscitation. Intra-aortic balloon pumps increase coronary perfusion and reduce myocardial oxygen demand in a variety of cardiac conditions. Extracorporeal membrane oxygenation can provide both respiratory and circulatory support to patients. Ventricular assist devices can provide support for not only patients with acute cardiogenic shock, but also for ambulant patients in the community setting.
