[Terminal cardiac failure. Circulatory assist devices].
There is a great variety of circulatory assist devices because of the diversity of clinical applications, age of the patient, required performances, energy used for activation... The oldest assistance device is intra-aortic balloon counterpulsation. There are two groups of devices: light, partial and short-term assist devices versus total, sophisticated and long-term machines. Examples of the first group are the Hemo-pump and Centrifugal pumps. Many of the second group are pneumatically driven: either external heterotopic uni/biventricular assist devices (Thoractec, Medos) or implantable heterotopic left ventricle (TCI), or orthotopic and implantable total artificial heart (Jarvik-CardioWest). The aim to assist the left ventricle over a longer period of time has lead laboratories to develop electrically powered ventricles implanted in the abdominal wall like the Novacor or HeartMate Systems. Because these new devices make patients more independent, they open the way for chronic applications as an alternative to transplantation.
