Abstract
Clinical use of artificial heart as a left ventricular assist devise (LVAD) for 3 patients with profound postoperative heart failure was reported. Progressive secure recovery of myocardial contraction had observed 4th or 5th day after LVAD use, and it was very important to improve the other organ dysfunction due to cardiopulmonary bypass or LOS. To get optimal organ perfusion, we devised and tried “Bisected Diastolic Driving (BDD)” in these cases with renal dysfunction, resulted in marked improvement. On the other hand, left ventricular function curves were calculated by pulse-wave method and were very useful to decide the time of LVAD weaning.
