[Diastolic reinforecement by intra-aortic balloon. Critical review of temorary mechanical ventricular assistance technic].

The treatment of the cardiogenic shock complicating acute myocardial infarction has been drastically improved by the progress in temporary mechanical cardiovascular support. The improvement of the synchronous assist device, such as the intra aortic balloon, associated with the progress in the monitoring of the patients, in the surgical treatment of myocardial insufficiency and ventricular abnormalities such as ventricular septal defect and mitral insufficiency, has changed the seroius prognosis in patients. A review of some theretical, physiological and clinical problems are discussed in this paper.
