Abstract
It is now 25 years ago that Dennis designed systems to assist a failing heart after open cardiac surgery, at a time when an open-heart case was a real hazard and the operative mortality was as high as 10%. The early concept has since been modified. Zwart and Litwak proposed systems to assist a failing heart via a transaortic access to the left ventricle; this concept is being discussed again, with implantation of a catheter in the left ventricle. Frazier now proposes unloading the left ventricle by means of a small rotary pump integrated in the catheter, which can handle an afterload of 100 mmHg.
