Abstract
This experimental study was planned for the purpous of demonstrating the effectiveness, especially renal blood flow and renal function of the left venticular assist device in swine. Regional renal blood flow was increased during LVAD assist. Renal cortical blood flow/renal (cortex+medulla) blood flow ratio was increased. So, the unbalance of the renal regional blood flow was repaired. CH2O and FENa resulted in no charge during LVAD assist, but creatinine clearance (CCr) was increased during LVAD assist. These results sttggested LVAD assist was effective for acute renal failure with left heart failure.
