Abstract
In the recent years IABP has been widely usedclini cally as amechanical circulatory assistance. However, there were a few patients who could not be weaned from profound cardiac failure after cardiac operation, in spite of IABP assistance. In our experimental studies onmechanical circulatory assistance for cardiogenic shock due to AMI efficacy of the LVAD was obviously revealed in comparison with another assisted circulation such as V-A bypass, or IABP+V-A bypass. Based on these experimental results, the LVAD was successfully applicated in the 68 Year-old female patient who underwent closure of ventricular septal rupture and A-C bypass for VSR following AMI. The patient was fortunately weaned from the LVAD and IABP one week after surgery. Our experiences concerning the LVAD in mechanical circulatory assistance were reported in detail.
